Description

''Geranium viscosissimum'' is a large, clumped tall perennial wild geranium. The stem, leaves, and flower stalks are covered with sticky hairs. The right-green leaves are dissected, many-toothed, and deeply-lobed. Its bloom period is April to September, depending on elevation and latitude. It has saucer-shaped, pink-to-purple flowers measuring with reddish-purple lines on the petals. They occur in an open cluster near the top of strong, branching and leafy flower stalks, which are tall.

enzymes capable of breaking down potential prey. ''Geranium viscosissimum'' displayed a capability to digest and absorb the 14C-labeled algal protein placed on the sticky trichomes that the plant possesses. However, it is not known whether the digestive enzymes were produced by the plant itself or surface microbes. Additionally, some definitions of carnivory require the plant to gain some tangible benefit in capturing and digesting prey, such as increased seed yield or growth. Such an experiment has not been done with this species.


Uses

The flowers and leaves of this species are edible, but reported to be astringent. The flowers can be added to salads or used as a garnish.


Medicinal

Blackfeet Indians used an infusion from this plant to treat diarrhea and gastric upset and urinary irritations. The root of this plant is astringent and was dried and powdered and used by Native Americans to stop external bleeding. An infusion of the leaves has also been used to treat colds and sore throats. The leaves and roots have been made into a poultice and used to treat sore eyes via an infusion.
