[9], The genus Allium (alliums) is characterised by herbaceous geophyte perennials with true bulbs, some of which are borne on rhizomes, and an onion or garlic odor and flavor.[16]. Two small subgenera, Butomissa and Cyathophora form a sister clade to the remaining five subgenera, with Butomissa as the first branching group. The reactive oxidant… Allium bulbs are easy to grow, and are incredibly long-lived. The generic name Allium is the Latin word for garlic, and the type species for the genus is Allium sativum which means "cultivated garlic". Allium tuberosum is a late-season bloomer from the onion family. Alliums aren’t too picky: In most cases, alliums grow in average garden soil and need full sun and good drainage. Many of the species of Allium have been used as food items throughout their ranges. Most gardeners are aware of the problems caused by weeds, but there are garden plants - readily available to buy - that have the potential to become a nuisance. Allium species occur in temperate climates of the Northern Hemisphere, except for a few species occurring in Chile (such as A. juncifolium), Brazil (A. sellovianum), and tropical Africa (A. spathaceum). 1. I have my blow torch ready. A. hollandicum 'Purple Sensation' is one of the most popular and has been given an Award of Garden Merit (H4). In spite of remarkable attributes—showy flowers that attract bees, butterflies, and hum - ... invasive, so it’s a good idea to check with your local Extension Service or public gar-den to find out which ones might show aggressive tendencies in your region. Allium flowers form dense balls of color at the top of strong stems, and they make excellent displays in the garden or in bouquets. Susan, thank you for your response. Not all allium varieties are well-behaved. Line one (the oldest) with three subgenera is predominantly bulbous, the second, with five subgenera and the third with seven subgenera contain both bulbous and rhizomatous taxa. Native to Europe but discovered in Pennsylvania in 2015, the Allium leafminer is a fly whose larvae feed on crops in the Allium genus, including onions, garlic and leeks. Amongst the remaining five subgenera, Rhizirideum forms a medium-sized subgenus that is the sister to the other four, larger, subgenera. [7][8], The decision to include a species in the genus Allium is taxonomically difficult, and species boundaries are unclear. Some species produce bulbils within the umbels, and in some species, such as Allium paradoxum, the bulbils replace some or all the flowers. [11] In some of the older classification systems, Allium was placed in Liliaceae. Alliums are an afterthought. The pest was seen targeting onions, leeks, garlic, chives, shallots, as well as green onions, with leeks being described as the most damaged host. Hairy allium is also called hairy garlic (Allium subhirsutum), it is a bit more aggressive (I have that too, but didn't plant it). Bulbs of the larger Alliums like A. gigantium and Globe Master are among our largest garden bulbs often 2 to 3 inches tall and 2 inches wide. Allium sphaerocephalon, just beginning to open. [38] These ornamental onions produce spherical umbels on single stalks in spring and summer, in a wide variety of sizes and colours, ranging from white (Allium 'Mont Blanc'), blue (A. caeruleum), to yellow (A. flavum) and purple (A. giganteum). [31], The major evolutionary lineages or lines correspond to the three major clades. (30-90 cm) in height. Houghton Mifflin, Boston. 1 Recipe. Drumstick allium plants are suitable for growing USDA plant hardiness zones 4 through 8. "1793 illustration from William Woodville: "Medical botany", London, James Phillips, 1793, Vol. Checklist of ornamental, https://en.wikipedia.org/w/index.php?title=Allium&oldid=991271271, Short description is different from Wikidata, Articles with unsourced statements from July 2013, Creative Commons Attribution-ShareAlike License, This page was last edited on 29 November 2020, at 05:19. The leaf blades are straight or variously coiled, but some species have broad leaves, including A. victorialis and A. tricoccum. I have never heard of Alliums as being invasive or aggressive. [22] (number of sections/number of species), Although this lineage consists of three subgenera, nearly all the species are attributed to subgenus Amerallium, the third largest subgenus of Allium. [17][18] The seeds are black, and have a rounded shape. Allium ‘Purple Rain’ is a cross between Allium ‘Purple Sensation’ and Allium Cristophii.It bears huge purple, globe-shaped flower heads measuring up to 15cm in diameter. The bulbs vary in size between species, from small (around 2–3 mm in diameter) to rather large (8–10 cm). I cut the flowers off last week because I wasn't sure if they would drop seeds and self-sow. The flowers last well and are perfect for cutting. It is sometimes confused with a very similar species, A. ramosum or fragrant-flowered garlic, but that plant blooms earlier in the year and has a slightly different leaf structure. Allium is a genus of monocotyledonous flowering plants that includes hundreds of species, including the cultivated onion, garlic, scallion, shallot, leek, and chives. This selection has not been known to reseed and is not invasive. Allium cepa (onion), Allium porrum (leek), Allium sativum (garlic), and Allium schoenoprasum(chive) contain organic sulfur compounds that are absorbed through the gastrointestinal tract and converted to highly reactive oxidants. 1 Review. Allium is a genus of monocotyledonous flowering plants that includes hundreds of species, including the cultivated onion, garlic, scallion, shallot, leek, and chives. They vary in height between 5 cm and 150 cm. Allium 'Millenium' is very easy to grow in full sun to part shade. Please let me know if I must add them to my list of gardening gaffes. Some bulbous alliums increase by forming little bulbs or "offsets" around the old one, as well as by seed. There are several poisonous species that are somewhat similar in appearance (e.g. [7] Many are used as food plants, though not all members of the genus are equally flavorful. [citation needed], Various Allium species are used as food plants by the larvae of the leek moth and onion fly[7] as well as some Lepidoptera including cabbage moth, common swift moth (recorded on garlic), garden dart moth, large yellow underwing moth, nutmeg moth, setaceous Hebrew character moth, turnip moth and Schinia rosea, a moth that feeds exclusively on Allium species. 2. Most early blooming alliums have foliage that tends to die-back early, as the plants go dormant for the summer. Resembles Allium giganteum but with smaller flower clusters. [17] A single known exception, Allium dregeanum occurs in the Southern Hemisphere (South Africa). I will take out the hairy garlic and keep the Beau Regard. This line may not be monophyletic. 1982. Within the lineage, the phylogeny is complex. Allium cowanii is an early flowering allium, bearing pretty, shaggy white flower heads in loose clusters. [33], Many Allium species have been harvested through human history, but only about a dozen are still economically important today as crops or garden vegetables. The fruits are capsules that open longitudinally along the capsule wall between the partitions of the locule. 3, Plate 168: Kew World Checklist of Selected Plant Families, "A subfamilial classification for the expanded asparagalean families Amaryllidaceae, Asparagaceae and Xanthorrhoeaceae", "A Solution to the C-Value Paradox and the Function of Junk DNA: The Genome Balance Hypothesis", Cope RB. (2010)[22] The modern era of phylogenetic analysis dates to 1996. Allium spp. Blooms in late spring, bearing tennis ball-size clusters of lilac flowers on stems 2 5 feet tall. Most people who grow their own vegetables will grow onions and leeks, they will often also grow garlic, shallots and chives, whilst those who are more adventurous might be growing garlic chives, tree onions, everlasting onions and welsh onions. This subgenus also contains the majority of the species in its lineage. Stalking the wild asparagus. These include onions (A. cepa), French shallots (A. oschaninii), leeks (A. ampeloprasum), scallions (various Allium species), and herbs such as garlic (A. sativum) and chives (A. schoenoprasum). Treatments tested for invasive pest on allium crops Date: July 1, 2020 Source: Cornell University Summary: Researchers field-tested 14 active ingredients in insecticides, applied in a … The lineage is considered to represent the most ancient line within Allium, and to be the only lineage that is purely bulbous, the other two having both bulbous and rhizomatous taxa. In: Klaus Kubitzki (editor). "Alliaceae" pages 70-78. Gardeners may buy these 'thug' plants unaware that, once established and given the right growing conditions, they can run amok. The ovaries are superior, and three-lobed with three locules. Professional Growing Information . The term Alliance has also been used for subgroupings within species, e.g. However, the genus has been shown to be monophyletic, containing three major clades, although some proposed subgenera are not. In the APG III classification system, Allium is placed in the family Amaryllidaceae, subfamily Allioideae (formerly the family Alliaceae). 23 products View. The characteristic Allium flavor depends on the sulfate content of the soil the plant grows in. The flower head consists of over 100 little star-shaped blooms arranged in an amazing globular starburst. [22], The third evolutionary line contains the greatest number of sections (seven), and also the largest subgenus of the genus Allium: subgenus Allium, which includes the type species of the genus, Allium sativum. I have three kinds of allium, but I am particularly concerned with the hairy allium. Zones US, MS, LS; USDA 6-8. Cooking does not reduce potential toxicity, and even powder forms can induce clinical signs. The flowers, which are produced on scapes are erect or in some species pendent, having six petal-like tepals produced in two whorls. For a brief history, see Li et al. The blossoms are borne atop the foliage of short gray-green basal leaves. Hairy allium is also called hairy garlic (Allium subhirsutum), it is a bit more aggressive (I have that too, but didn't plant it). [22], Nearly all the species in this lineage of five subgenera are accounted for by subgenus Melanocrommyum, which is most closely associated with subgenera Vvedenskya and Porphyroprason, phylogenetically. Some of the subgenera correspond to the once separate genera (Caloscordum, Milula, Nectaroscordum) included in the Gilliesieae. Some species (such as Welsh onion A. fistulosum) develop thickened leaf-bases rather than forming bulbs as such. [19][20], With over 850 species[21] Allium is the sole genus in the Allieae, one of four tribes of subfamily Allioideae (Amaryllidaceae). Allium nigrum, and for subsections. 4. Allium spicatum had been treated by many authors as Milula spicata, the only species in the monospecific genus Milula. Allium flowers range from purple, burgundy, lilac, silvery amethyst, pink, blue, to yellow and white. Piper RECIPE. Some sources refer to Greek ἀλέω (aleo, to avoid) by reason of the smell of garlic. Hardiness: Alliums can be grown in Zones 3 to 9, depending upon the species and cultivar. Very beautiful and easy to grow, I would cover during frost areas though. That is what I have. [7][47], The genus includes many economically important species. Allium … 'Serendipity' Allium hybrid USPPAF, Can PBRAF. Within the lineage Amerallium is a sister group to the other two subgenera (Microscordum+Nectaroscordum). James L. Brewster, "Onions and Other Alliums" (Wallingford: CABI Publishing, 2008), Haim D. Rabinowitch, Leslie Currah, "Allium Crop Sciences: Recent Advances" (Wallingford: CABI Publishing, 2002), Penny Woodward, "Garlic and Friends: The History, Growth and Use of Edible Alliums" (South Melbourne: Hyland House, 1996). Gibbons, E. 1962. They simply grow happily where you put them, providing color and texture year after year. Allium triquetrum is a bulbous flowering plant in the genus Allium (onions and garlic) native to the Mediterranean basin.It is known in English as three-cornered leek, and in Australia and New Zealand as onion weed. Some become weeds that are nearly impossible to get rid of, especially in mild climates. (2006)[27] and Li (2010). [32], Species grow in various conditions from dry, well-drained mineral-based soils to moist, organic soils; most grow in sunny locations, but a number also grow in forests (e.g., A. ursinum),[7] or even in swamps or water. Well, some of us have better luck with Allium sphaerocephalon, drumstick alliums. A type of ornamental onion, also known as round-headed leek, drumstick allium (Allium sphaerocephalon) is appreciated for the egg-shaped blooms that appear in early summer.Hollow, grayish-green foliage provides lovely contrast to the pink to rosy-purple drumstick allium flowers. Allium wild onion, wild garlic This plant can be weedy or invasive according to the authoritative sources noted below.This plant may be known by one or more common names in … It’s well suited to growing in drifts at the front of an informal boxer, but also works well when grown in pots. Treatments tested for invasive pest on allium crops By Krishna Ramanujan | June 30, 2020. SANDRA LAGASSE, South Carolina, United States, 30 weeks ago. The inner coats of the bulbs are membranous. The research team, led by senior author Brian Nault, professor of entomology at Cornell AgriTech and one of the nation’s leading Allium leafminer management experts, found that several traditional chemical insecticides worked best against the invasive insect. Español UK Portuguese. Allium is one of about fifty-seven genera of flowering plants with more than 500 species. Some have been used as traditional medicines. [25], Linnaeus originally grouped his 30 species into three alliances, e.g. Ask an Expert is made up of groups and individual experts. Hi! [22], The three evolutionary lineages and 15 subgenera represent the classification scheme of Friesen et al. Are Alliums Invasive? The allium leafminer, also known as the onion leafminer, was first spotted in Lancaster County, PA, in December 2015, making it the first confirmed infestation in the western hemisphere. Amerallium is strongly supported as monophyletic. × proliferum) the bulbils are few, but large enough to be pickled. The bulbs are solitary or clustered and tunicate and the plants are perennialized by the bulbs reforming annually from the base of the old bulbs, or are produced on the ends of rhizomes or, in a few species, at the ends of stolons. It hasn't caused me any problems, but if you are concerned, remove that one but leave the purple alliums. [citation needed], The genus Allium has very large variation between species in their genome size that is not accompanied by changes in ploidy level. This genus contains a number of species that are commonly cultivated as food plants. Among the last of the perennials to bloom, its flowers often don't open until late September or October. [15] It is by far the largest genus in the Amaryllidaceae, and also in the Alliaceae in classification systems in which that family is recognized as separate. [29], Subsequent molecular phylogenetic studies have shown the 2006 classification is a considerable improvement over previous classifications, but some of its subgenera and sections are probably not monophyletic. The cooking and consumption of parts of the plants is due to the large variety of textures, and flavours, which may be strong or weak, that they can impart to the dish they are used in. [6], Carl Linnaeus first described the genus Allium in 1753. Allium Species - the Perennial Onions. Veterinary Medicine 2005, "Notes on systematics and taxonomy for the Italian vascular flora. Gledhill, David (2008). [22] The genus is especially diverse in the eastern Mediterranean. Available as 5 bulbs, 10 bulbs, 15 bulbs. They don’t become invasive and they don’t need constant attention. By contrast, other species (such as invasive A. triquetrum and A. ursinum) can become troublesome garden weeds.[37][39]. Robust and extraordinarily beautiful, Nectaroscordum siculum (Sicilian Honey Garlic) displays showy clusters of gracefully drooping bell-shaped flowers combining cream, pink and green tints rising on a tall, leafless stem atop blue-gray, twisted basal leaves. [22], The majority of Allium species are native to the Northern Hemisphere, being spread throughout the holarctic region, from dry subtropics to the boreal zone,[22] predominantly in Asia. Red blood cells contain hemoglobin, the major oxygen carrying protein in the body. In fact, I was told at an OHS meeting that one gardener found them as invasive as garlic chives. [22], Genus of flowering plants in the family Amaryllidaceae. It may be propagated in fall by digging it up and dividing the rhizome with the bulblets attached. [22] Some progress is being made using molecular phylogenetic methods, and the internal transcribed spacer (ITS) region, including the 5.8S rDNA and the two spacers ITS1 and ITS2, is one of the more commonly used markers in the study of the differentiation of the Allium species. [7][8][12][13][14] Molecular phylogenetic studies have shown this circumscription of Liliaceae is not monophyletic. Use of chloroplast DNA polymorphisms for the phylogenetic study of, "Molecular and morphological revision of the, "Minisatellite telomeres occur in the family Alliaceae but are lost in Allium", World Checklist of Selected Plant Families, Pacific Bulb Society: Rhizomatous Alliums, Reinhard M. Fritsch. The umbels are subtended by noticeable spathe bracts, which are commonly fused and normally have around three veins. It may be propagated in fall by digging it up and dividing the rhizome with the bulblets attached. That is what I have. All alliums die to the ground after bloom, even in mild climates. 3. [36] These include A. cristophii and A. giganteum, which are used as border plants for their ornamental flowers, and their "architectural" qualities. Bees love it. Knud Rahn. Detailed studies have focused on a number of subgenera, including Amerallium. It will tolerate soil of any fertility and will grow in clay soil. A small number of species have tuberous roots. Allium 'Serendipity' is very easy to grow in full sun to part shade.

This is the Allium that started it all--the really beautiful tall relative of onions, leeks, and chives that has now taken its place in flower gardens. Maybe it depends on the kind of allium as to its invasive properties? Allium Unifolium (Oneleaf Onion) is a compact perennial with delicate clusters of up to 30 fairly large, star-shaped, satiny, rose-pink flowers. Furthermore, traditional classications had been based on homoplasious characteristics (the independent evolution of similar features in species of different lineages). Plants of the genus Allium produce chemical compounds, mostly derived from cysteine sulfoxides, that give them a characteristic onion, or garlic, taste and odor. Allium 'Beau Regard' is a drumstick allium and is in no way invasive. [30] Subgenus Melanocrommyum has also been the subject of considerable study (see below), while work on subgenus Allium has focussed on section Allium, including Allium ampeloprasum, although sampling was not sufficient to test the monophyly of the section. Add your review. 1. Both the English name and the specific epithet triquetrum refer to the three-cornered shape of the flower stalks. In most cases, both bulb and leaves are edible. 1998. Lloyd, Christopher & Rice, Graham, (1991). Plants range from 11-35 in. Only Photos; Show All; Sort by: Allium amplectens 'Graceful Beauty' £7.96 Was £9.95 Now £7.96 Starting at £3.16. [22][28] The terminology has varied with some authors subdividing subgenera into Sections and others Alliances. Foliage Leaves are tubular, hollow, slender, and have a waxy appearance. [7][35], Many Allium species and hybrids are cultivated as ornamentals. Ozawa allium (Allium thunbergii 'Ozawa'): A tidy, clump-forming plant that grows 18″ to 20″ high. Allium … and cvs. Seldom browsed by deer. Smaller varieties are about the size of … Since then, many attempts have been made to divide the growing number of recognised species into infrageneric subgroupings, initially as sections, and then as subgenera further divided into sections. It would help me to know how long have you had your alliums (it took a few years for my red trumpet vine to become invasive), and do all alliums spread at the same rate? allium aflatunense. If this sounds like something you could use in your garden, let’s dig in. 2", "Morphological and molecular data reveal a new species of, "Phylogeny and new intrageneric classification of, "More than a pretty face - ornamental "drumstick onions" of, "Testing the utility of matK and ITS DNA regions for discrimination of Allium species", "Phylogeny and biogeography of Allium (Amaryllidaceae: Allieae) based on nuclear ribosomal internal transcribed spacer and chloroplast rps16 sequences, focusing on the inclusion of species endemic to China", A. Samoylov, N. Friesen, S. Pollner, P. Hanelt. Leaves: Allium leaves tend to be long and strappy.Some—like the cork-screw allium—remain attractive all season, with a blue-green color that complements the flowers. Plants produce from one to 12 leaves, most species having linear, channeled or flat leaf blades. The following cultivars, of uncertain or mixed parentage, have gained the Royal Horticultural Society's Award of Garden Merit: Dogs and cats are very susceptible to poisoning after the consumption of certain species. Part of what I love about ornamental alliums in general is that they’re a mild-mannered plant. [8][37] Several hybrids have been bred, or selected, with rich purple flowers. I don't want an invasive/weedy plant in my garden, but I definitely want to keep the plant if it is not invasive. This selection has not been known to reseed and is not invasive. I have had my share of "I'm sorry I planted that" from watch chain sedum to black-eyed Susan, and I will gladly snuff the life out of these allium now if they could potentially be "jump the fencers." Blooming in late spring to early summer, this charming Allium … [22] A few species are native to Africa and Central and South America. [23], When Linnaeus[1] formerly described the genus Allium in his Species Plantarum (1753), there were thirty species with this name. [7] In the rare occurrence of sulfur-free growth conditions, all Allium species completely lose their usual pungency. The difficulties arise from the fact that the genus displays considerable polymorphism and has adapted to a wide variety of habitats. The terete or flattened flowering scapes are normally persistent. The leaves are sessile, and very rarely narrowed into a petiole. [7] Various Allium have been cultivated from the earliest times, and about a dozen species are economically important as crops, or garden vegetables, and an increasing number of species are important as ornamental plants. Toxicology Brief: Allium species poisoning in dogs and cats. It will tolerate soil of any fertility and will grow in clay soil. New species continue to be described[21] and Allium is one of the largest monocotyledonous genera,[22] but the precise taxonomy of Allium is poorly understood,[22][21] with incorrect descriptions being widespread. David McKay, New York. Allium Ltd, develops, manufactures and sells the most innovative long-term, fully covered, expandable and retrievable stents for the treatment of the various obstructions in the urinary and GI tract, Allium’s unique stent solutions are providing a minimally invasive, reversible alternative solution compared to the common practice of invasive or short time solutions. There are two centres of diversity, a major one from the Mediterranean Basin to Central Asia and Pakistan, while a minor one is found in western North America. Susan, thank you so much for your help. The generic name Allium is the Latin word for garlic,[4][5] and the type species for the genus is Allium sativum which means "cultivated garlic". I planted bulbs to get the hairy allium, so one would assume that the hairy allium would multiply via a bulb; however, I believe allium are related to onion weed, and I get that popping up all over without having planted onion weed bulbs, so perhaps allium spreads by seed as well as by bulb. "The Names of Plants". Flowering in June, it’s a good choice for growing with earlier-flowering alliums such as ‘Purple Sensation’, to extend the season. ~Donna. He placed Allium in a grouping he referred to as Hexandria monogynia (i.e. Cambridge University Press. These add pizzazz to your border, and are great for cutting. [21], Allium includes a number of taxonomic groupings previously considered separate genera (Caloscordum Herb., Milula Prain and Nectaroscordum Lindl.) The flowers form an umbel at the top of a leafless stalk. For example, I had to pull out my Sedum Watch Chain Stonecrop because it became invasive, but I am still enjoying my Sedum Blue Spruce. In 2000, it was shown to be embedded in Allium. The drainage is critical because so many of … Several species can form many bulbils in the flowerhead; in the so-called "tree onion" or Egyptian onion (A. Estimates of the number of species are as low as 260,[9] and as high as 979.[10]. The flowers have one style and six epipetalous stamens; the anthers and pollen can vary in color depending on the species. The bad news is that dormant bulbs can remain in the soil for up to six years. [26] In 2006 Friesen, Fritsch, and Blattner[27] described a new classification with 15 subgenera, 56 sections, and about 780 species based on the nuclear ribosomal gene internal transcribed spacers. These three genera are late-branching whereas the remaining two subgenera, Caloscordum and Anguinum, are early branching. I planted allium (beau regard and hairy allium)and thought they were intriguing until I read that allium are invasive (or "weedy"). Foliis caulinis planis. Native to Europe but discovered in Pennsylvania in 2015, the Allium leafminer is a fly whose larvae feed on crops in the Allium genus, including onions, garlic and leeks. [34] Genome sizes vary between 7.5 Gb in A. schoenoprasum and 30.9 Gb in A. ursinum, both of which are diploid. Peterson, R.P. Of the latter, 138 species occur in China, about a sixth of all Allium species, representing five subgenera. Part Sun to Sun. In my garden they have not spread at all beyond the bulbs I originally planted. It hasn't caused me any problems, but if you are concerned, remove that one but leave the purple alliums. The inflorescences are umbels, in which the outside flowers bloom first and flowering progresses to the inside. six stamens and one pistil)[24] containing 51 genera in all. Another late-bloomer that flowers in autumn. This generally highly prized allium, with heads of soft-chocolate-pink-striped bells, is also known as Allium bulgaricum and Nectaroscordum siculum, (Sicilian honey garlic). Meanwhile, the number of new species continued to increase, reaching 800 by 2009, and the pace of discovery has not decreased. Appearance Allium vineale is a perennial plant that originates from a bulb. Native to southeastern Asia, it is known by several common names including garlic chives, Chinese chives or Chinese leek. in North America, death camas, Toxicoscordion venenosum), but none of these has the distinctive scent of onions or garlic. Many alliums have basal leaves that commonly wither away from the tips downward before or while the plants flower, but some species have persistent foliage. Allium 'Beau Regard' is a drumstick allium and is in no way invasive. [33] This remarkable variation was noted in the discussion of the evolution of junk DNA and resulted in the Onion Test, a "reality check for anyone who thinks they have come up with a universal function for junk DNA". The bulbs' outer coats are commonly brown or grey, with a smooth texture, and are fibrous, or with cellular reticulation. 5. A Field Guide to Edible Wild Plants: Eastern and central North America.
