is a not very well known low groundcover in the Northwest.
The ones in the garden here are grown in part shade, under
a mixed woodland canopy. Early to flower in the spring, the
'flowers' start off acid yellow and age to a beautiful chartreuse.
(The center of the flower consists of many individual flowers,
the five 'petals' are modified bracts). This plant can benefit
from being divided every three to five years, as it can become congested.
Also, seedlings will emerge, but never in numbers to warrant any concern
