Trillium albidum

Habit: a low growing herbaceous perennial rising from a rhizome that resembles a bee abdomen. An aerial view of an individual plant resembles a triangle with the white flower in the center.   The slightly mottled leafy bracts directly subtend the sessile white three petaled flower, this is a good indicator of telling T. albidum apart from T. ovatum, whose flower rises above the leafy bracts

Ecology: found growing in open areas, and dense forests on nutrient rich slopes in Oregon and California, from 300-600 ft (100-200 m)

Growing Conditions:  dappled light, in moist nutrient rich soil.

Trillium is a very long lived genus, with some species known to live for multiple decades.  In the wild most trillium species take 7-10 years to produce flowers from seed.
