Flowers about 1 inch across. Has two color phases: either all 5 petals pale lilac or lavender, or the upper 2 petals deep, velvety purple and the 3 lower petals pale lilac to lavender. Rare color patterns are white and combinations of the above. The center of the united stamens is always deep orange. Blooms April-June. Leaves deeply dissected “like a bird’s foot.” Leaves developing later in the season have somewhat wider, straplike segments.
