'''''Colchicum''''' ({{IPAc-en|ˈ|k|ɒ|l|tʃ|ᵻ|k|əm}} {{respell|KOL|chik|əm}} or {{IPAc-en|ˈ|k|ɒ|l|k|ᵻ|k|əm}} {{respell|KOL|kik|əm}})<ref>{{cite web |url=http://dictionary.reference.com/browse/colchicum?r=75&src=ref&ch=dic |title=Colchicum - Define Colchicum at Dictionary.com |work=Dictionary.com}}</ref> is a [genus](/source/genus) of [perennial](/source/perennial_plant) [flowering plant](/source/flowering_plant)s containing around 160 [species](/source/species) which grow from bulb-like [corm](/source/corm)s. It is a member of the botanical [family](/source/Family_(taxonomy)) [Colchicaceae](/source/Colchicaceae), and is [native](/source/native_plant) to West [Asia](/source/Asia), [Europe](/source/Europe), parts of the [Mediterranean](/source/Mediterranean_Sea) coast, down the [East Africa](/source/East_Africa)n coast to [South Africa](/source/South_Africa) and the [Western Cape](/source/Western_Cape). In this genus, the [ovary](/source/Ovary_(botany)) of the [flower](/source/flower) is underground. As a consequence, the [styles](/source/Stigma_(botany)) are extremely long in proportion, often more than {{cvt|10|cm|0}}. All species in the genus are toxic.<ref>{{cite book |last=Barceloux |first=Donald G. |date=2008 |title=Medical Toxicology of Natural Substances: Foods, Fungi, Medicinal Herbs, Plants, and Venomous Animals. |publisher=Wiley |pages=693–702 |isbn=978-0471727613}}</ref>

==Common names==
The common names '''autumn crocus, meadow saffron''' and '''naked lady''' may be applied to the whole genus or to many of its species; they refer to the "naked" [crocus](/source/crocus)-like flowers that appear in late summer or autumn, long before the strap-like foliage which appears in spring.{{cn|date=April 2025}}

''Colchicum'' and ''Crocus'' look alike and can be confused by the casual observer. To add to the confusion, there are autumn-flowering species of crocus. However, colchicums have 3 styles and 6 [stamen](/source/stamen)s, while crocuses have 1 style supporting 3 long stigmas and 3 stamens.<ref>A Handbook of ''Crocus'' and ''Colchicum'' for Gardeners, page 154</ref> In addition, the [corm](/source/corm) structures are quite different—in ''Colchicum'', the corm is irregular, while in crocuses, the corm is like a flattened ball.<ref>A Handbook of Crocus and Colchicum for Gardeners, page 20, elsewhere</ref> ''[Crocus](/source/Crocus)'' is in the iris [family](/source/Family_(taxonomy)), [Iridaceae](/source/Iridaceae).

==Etymology==
The name of the genus derives from Κολχίς ([Colchis](/source/Colchis)), the [Ancient Greek](/source/Ancient_Greek) name for the region of კოლხეთი ([Kolkhida](/source/Kolkhida)) in modern [Georgia](/source/Georgia_(country)) ([Caucasus](/source/Caucasus)). Colchis features in [Greek mythology](/source/Greek_mythology) as the land to which the [Argonauts](/source/Argonauts) journeyed in quest of the [Golden Fleece](/source/Golden_Fleece) and where [Jason](/source/Jason) encountered [Medea](/source/Medea). The Greek [toponym](/source/toponym) ''Colchis'' is thought by scholars to derive from the [Urartian](/source/Urartian) ''Qulḫa'', pronounced "Kolcha" (guttural "ch" - as in Scots ''loch'').<ref>Lordkipanidze, O. (1991). Archeology in Georgia, Weinheim, 110.</ref>

==Relationships==
''[Colchicum melanthioides](/source/Colchicum_melanthioides)'', also known as ''Androcymbium melanthioides'',<ref>{{citation |url=http://www.theplantlist.org/tpl1.1/record/kew-346509 |title=The Plant List |accessdate=27 May 2016}}</ref> is probably the best known species from the [tropical](/source/tropics) regions. In contrast to most temperate colchicums, the flower and leaves are produced at the same time, the white flowers usually in a small corymb that is enclosed by white bracts. Close relatives such as ''[Colchicum scabromarginatum](/source/Colchicum_scabromarginatum)'' (''Androcymbium scabromarginatum'') and ''[Colchicum coloratum](/source/Colchicum_coloratum)'' (''Androcymbium burchellii'') have flowers with very short stalks and may be pollinated by [rodent](/source/rodent)s.<ref>{{cite journal |author=Ciara Kleizen, Jeremy Midgley & Steven D. Johnson |year=2008 |title=Pollination systems of ''Colchicum'' (Colchicaceae) in Southern Africa: evidence for rodent pollination |journal=[Annals of Botany](/source/Annals_of_Botany) |volume=102 |issue=5 |pages=747–755 |doi=10.1093/aob/mcn157 |pmid=18723860 |pmc=2712380}}</ref>

==Cultivation==
Temperate colchicums are commonly grown in gardens as ornamental flowers. Species found in cultivation include:

In the United Kingdom, the [National Collection](/source/NCCPG_National_Plant_Collection) of colchicums is maintained at [Felbrigg Hall](/source/Felbrigg_Hall), [Norfolk](/source/Norfolk).

==Medicinal uses and poisonous properties==
Plants in this genus contain toxic amounts of the [alkaloid](/source/alkaloid) [colchicine](/source/colchicine) which is used pharmaceutically to treat [gout](/source/gout) and [Familial Mediterranean fever](/source/Familial_Mediterranean_fever).<ref>{{cite journal |last1=Amrollahi-Sharifabadi |first1=Mohammad |last2=Seghatoleslami |first2=Ahmad |last3=Amrollahi-Sharifabadi |first3=Maryam |last4=Bayani |first4=Farajali |last5=Mirjalili |first5=Mahdi |title=Fatal Colchicine Poisoning by Accidental Ingestion of Colchicum persicum: A Case Report |journal=American Journal of Forensic Medicine & Pathology |date=December 2013 |volume=34 |issue=4 |pages=295–298 |doi=10.1097/PAF.0000000000000059 |pmid=24196723 |s2cid=12811749 }}</ref> The use of the [root](/source/root)s and seeds in traditional medicine is thought to have arisen due to the presence of this drug.<ref>{{cite book |last=Stuart |first=M. |date=1979 |title=The Encyclopedia of Herbs and Herbalism |publisher=Orbis Publishing London |isbn=0-85613-067-2}}</ref>

Its [leaves](/source/leaf), [corm](/source/corm) and [seed](/source/seed)s are [poison](/source/poison)ous.
