Identification
Rattlesnake-plantain is an evergreen perennial with stems to 45 cm tall. Its leaves are all basal and form a flattened rosette. The leaves are thick, oval- or elliptic-shaped, and dark green with white mottling or striping particularly along the midrib. The dull white to greenish flowers cluster in a long, dense spike along the end of the stem. Most of the flowers orient to one side.
Habitat & Range
Rattlesnake-plantain grows on humus in shaded, dry to moist coniferous forests from low to middle elevations. It commonly grows among mosses. Its west coast range extends from Alaska to Mexico; it is also found in eastern Canada and parts of the United States (map).
Similar Species
The flattened basal leaf rosette helps differentiate rattlesnake-plantain from orchids with similar terminal flower spikes, such as white bog-orchid (Platanthera dilatata) and ladies' tresses (Spiranthes romanzoffiana). Its leaf shape is similar to that of common plantain (Plantago major), but the latter does not have a flattened leaf rosette.
Human Uses
One traditional use of the plant was as a balloon by Stl'atl'imx children. By rubbing the leaves together the top and bottom layers can be separated; blowing in the stem inflates this leaf 'pouch.'
Intriguing Info
Rattlesnake-plantain is an orchid, but was mistaken for a plantain by settlers because of its similarity in leaf shape to common plantain.
