PRINCE'S PLUME
Stanleya pinnata

Prince's plume is a large perennial sometimes over 3 feet tall. Older plants may be woody at the base.
The leaves are smooth and waxy. Hundreds of bright yellow flowers collect on a stalk a foot or more long. Slender seedpods about two inches long form progressively as the flowers mature from the
bottom of the stalk upwards.
It can bloom over a period of many weeks, sometimes months.
These plants thrive under light grazing by cattle. Prince's plume is one of the few members of the
mustard family known to accumulate and indicate the presence of selenium,
a poisonous element present in many western soils.
