Abstract

This list of ornamental Allium species and cultivars presents about 250 species (plus c. 50 synonyms and spelling variants, and c. 20 hybrids and intraspecific taxa), and 240 cultivars. It was compiled using recent catalogues (printed ones and in electronic form), and other kinds of offers of plant and bulb traders. These sources were especially analyzed for ornamental properties. Species and cultivars solely offered as vegetables, spice or medical plants were ignored, but those with dual use including ornamental characters were accepted. The formulations marking this borderline were sometimes diffuse, and thus there was a visible subjective influence. Catalogues of botanic gardens and of societies of plant enthusiast were not considered because such institutions and the members of those organizations intend to complete own collections and not to broadcast plants of ornamental value. Species and after them the cultivars are arranged in alphabetical order. A list of complete names for Allium subgenera and sections and a list of references complete this checklist

General introduction
Though Allium species and cultivars constitute only a small part of the huge diversity of the commercially available bulb plants, Allium is one of the largest genera of monocots and is
disreputable for a complicated taxonomic structure. The different taxonomies currently still in use are partly referring to the last Allium monograph of Regel (1875; about 260 accepted
species with about 260 synonyms, Nothoscordum, Nectaroscordum and Caloscordum included in Allium, 6 sections and many unnamed subdivisions). During 50 years after Regel's
monograph (till 1925) about 375 valid Allium species were newly described, but Krause (1930) mentioned only about 280 species for Allium (excl. Nothoscordum and Caloscordum)
contributing thus to the then existing confusion. In the next period up to 1990, again about 400 valid species were described, and Stearn (1992) accepted about 750 species for Allium
(excluding Nothoscordum, Nectaroscordum and Caloscordum). After 1990 till 2014, again 235 species and intraspecific taxa were newly described, and at the end of 2014 the number of
accepted Allium species exceeded 930 (excluding Nothoscordum but including Nectaroscordum, Milula, and Caloscordum; Kew World Checklist). This seems a realistic estimation against
the background of more than 1700 known Allium synonyms.
Allium species are known since ancient times. The early reports known focus on species used by man as spices, vegetables, and medical plants. Common onion, garlic, rakkyo and some
more own world-wide or at least continent-wide importance as cultivated plants, others are only regionally and locally cultivated, or are collected in the wild for consumption. Characterizing
chemical compounds in Allium plants are polysaccharids (mainly fructans), polyphenols, saponins, and especially several compounds of the sulfur-containing amino acid cysteine whose
enzymatic degradation products are responsible for most of the medical, olfactory, and taste properties of the consumed plant parts. Other compounds contribute to the remarkable tonic
properties of some species (Keusgen & Fritsch 2008). The different amounts of chemical compounds are responsible for the often strong and extremely varying odor and taste of different
Allium plants. Only some species of subg. Melanocrommyum may be nearly odorless.
Allium plants exhibit a wide range of different phenotypes, many of them with high ornamental value. One can assume that also the ornamental value of many Allium species was known
since ancient times, and some of them entered the ornamental and medical garden plots much earlier than in medieval times when some inventories mentioned Allium species. Already in
pre-Linnean times a few Allium species were scientifically recognized from cultivated specimens, a practice still more evident in later centuries when botanical gardens and other research
collections were established. If a species was described from garden plants, this does not automatically present evidence for being already present in many gardens and offered in the
2
trade at the very time when described. During the last two decades, rather many ornamental Allium species and cultivars were introduced into the bulb trade, and the checklist of the Dutch
Royal Bulbgrowers Association (KAVB 1991) is outdated now. There was also much progress in the classification of Allium, and the "classical" affiliation of species to a handful of sections
was replaced by a much more detailed classification. Therefore the modern affiliation of species is added, that also includes information about genetic relationships.
About this list
This list of ornamental Allium species and cultivars presents about 250 species (plus c. 50 synonyms and spelling variants, and c. 20 hybrids and intraspecific taxa), and 240 cultivars.
It was compiled using recent catalogues (printed ones and in electronic form), and other kinds of offers of plant and bulb traders. These sources were especially analyzed for ornamental
properties. Species and cultivars solely offered as vegetables, spice or medical plants were ignored, but those with dual use including ornamental characters were accepted. The
formulations marking this borderline were sometimes diffuse, and thus there was a visible subjective influence. Catalogues of botanic gardens and of societies of plant enthusiast were not
considered because such institutions and the members of those organizations intend to complete own collections and not to broadcast plants of ornamental value.
Species and after them the cultivars are arranged in alphabetical order.
The contents of most columns was copied from the sources used and unites different information in many cases -- too often single sources delivered incomplete or contradictory (separated
by a slash) information. These data were not completed from taxonomic sources like Floras because cultivated plants may have been selected for morphological and physiological
characters rarely met in wild plants. In those cases one or several column fields remained void for a certain item. The "origin" column mentions the offspring of a cultivar or the source of
the material distributed in the trade (not the natural area of distribution of a species!) as far as available in the sources. Horticultural assessments (like "A.M." = Award of Merit), it was
added to the column "Use" if suitable information was found. The column "Remarks" contains mainly additional information selected by the compiler, "very rarely offered" means found in
1-2 catalogues, "rarely offered" in 3-5 catalogues. The column "Classification" presents the affiliation to subgenera and sections according to Friesen et al. (2006), Khassanov et al. (2011,
2013), Fritsch et al. (2010), and Fritsch (2012) accepting 15 subgenera and about 80 sections. Also this classification is still under discussion and represents no more than an
contemporary approach to a natural classification. Despite former Allium classifications used sections in a much wider sense (sensu lato = s. lat.) including also species separated in other
groups today, nomenclatural rules order these sections (and also a few subgenera) to remain in use. Commonly they comprise today less species (they are applied in the narrow sense =
sensu stricto = s. str.). Therefore these additions were given where necessary.
The taxonomic identity of the species and cultivars listed could not be checked, but the compiler intended to use orthographically correct binomina and author names according to the
present rules of the International Code of Nomenclature for Algae, Fungi and Plants. Botanically undescribed names used in catalogues were marked by the author name "hort." (=
hortorum, of gardens). The compiler changed scientific names only in those cases when it seemed him unavoidable in cases of clear errors, but expressed his doubts about correct names
in some more cases. It remains a matter of opinion whether a plant seller is responsible for the correct as possible naming of botanical species and of photos accompanying the offer -- is
an (perhaps only orthographically) incorrect name generally an important fault of these goods, or only clear mis-identifications? Also in these cases the borderline is diffuse … No doubt
that botanical gardens and other research or teaching collections are subject to more strict rules regarding correct determinations and botanical names.
Cultivar names affiliated in this list may be registered trademarks being subject to restricted commercial use.
