A fragrant, purple flower. Full to partial shade. Distinguished by two paired, pinnately cleft or divided leaves on the stem. The yellow petals make a flower about 2-inches across. Full to partial shade.
Soil needs low to rich organic content and average moisture.
Requires 2 years to flower and then dies, but can self-seed. Good for meadows and sometimes perennial gardens. The most densely downy species. Bloom is not as pretty as the leaf. Likes the woods.
