'''''Kalmia''''' is a [[genus]] of about 7 [[species]] of [[evergreen]] [[shrub]]s from 0.2-5 m tall, in the family [[Ericaceae]]. They are native to [[North America]] (mainly in the eastern half of the continent) and [[Cuba]]. They grow in [[acid]]ic soils, with different species in wet acid bog habitats (''K. angustifolia, K. polifolia'') and dry, sandy soils (''K. ericoides, K. latifolia'').

''Kalmia'' is named after the Finnish botanist [[Pehr Kalm]], who collected it in eastern North America.

The [[leaf|leaves]] are 2-12 cm long, simple lanceolate, and arranged spirally on the stems. The [[flower]]s are white, pink or purple, in corymbs of 10-50, reminiscent of [[Rhododendron]] flowers but flatter, with a star-like calyx of five conjoined [[petal]]s; each flower is 1-3 cm diameter. The [[fruit]] is a five-lobed capsule, which splits to release the numerous small [[seed]]s.

The foliage is toxic if eaten, with [[sheep]] being particularly prone to poisoning, hence the name '''lambkill''' used for some of the species. Other names for Kalmia, particularly ''Kalmia angustifolia,'' are '''sheep-laurel, lamb-kill, calf-kill, kill-kid, and sheep-poison,'''<ref name="NHEST">[http://www.nhest.org/penquis/pentreelist.html Natural History Education, Science, Technology] regarding alternate names, accessed March 30, 2007.</ref> which may be written with or without the hyphen. (See species list below.) "Kid" here refers to a young [[goat]], not a human child, but the foliage and twigs are toxic to humans as well.

It has also been called '''[[spoonwood]]''' because Kalm was told by Dutch settlers of North America that Native Americans made spoons from the wood.<ref name="">[http://books.google.com/books?id=aD12iEgGUlgC&pg=PA61&lpg=PA61&dq=spoonwood+spoons&source=web&ots=hDhJ3qQ5FH&sig=0cI_-ay9QZumYMYTv14IzS2I7-4 Plants of Colonial Days] by Raymond Leech Taylor, p. 61. (1996) ISBN: 0486294048. Accessed March 30, 2007.</ref> Given its toxicity, this may be folklore rather than scientific fact.

Kalmias are popular [[garden]] shrubs, grown for their decorative flowers. They should not be planted where they are accessible to livestock due to the toxicity.

''Kalmia'' species are used as food plants by the [[larva]]e of some [[Lepidoptera|lepidopteran]] species including ''[[Coleophora|Coleophora kalmiella]]'' which feeds exclusively on ''Kalmia''.
