Kalmia latifolia (Mountain-laurel) is a flowering plant in the family Ericaceae, native to the eastern USA, from southern Maine south to northern Florida, and west to Indiana and Louisiana.
It is an evergreen shrub growing to 3-9 m tall. The leaves are 3-12 cm long and 1-4 cm wide. Its flowers are star-shaped, ranging from red to pink to white, and occurring in clusters. It blooms between May and June. All parts of the plant are poisonous.
The plant is naturally found on rocky slopes and mountainous forest areas. The plant often grows in large thickets, covering large areas of forest floor.
It is also known as Ivybush, Calico Bush, Spoonwood (because native Americans used to make their spoons out of it), Sheep Laurel, Lambkill and Clamoun.
Mountain-laurel is the state flower of Connecticut and Pennsylvania.
The plant was first recorded in America in 1624, but it was named after Pehr Kalm, who sent samples to Linnaeus in the 18th century.
Cultivation and uses
The plant was originally brought to Europe as an ornamental plant during the 18th century. It is still widely grown for its attractive flowers. Numerous cultivars have been selected with varying flower color.References
