Twinleaf
Jeffersonia diphylla

• Flower: Single White flowers, regular, 8-12 petals
• Leaves: basal leaves on long stalks, divided into 2 leaflets
• Size: Flowers 1" across; plant 5-10" high in bloom
• Habitat: Rich woods
• Blooms: April-May

Twinleaf seems to be in bloom for a span of about 4 days—some years I miss it entirely. If you miss the flower, you can still catch the distinctive seed pod, which looks sort of like a butterfly chrysylis. Plentiful in Hinkley and Brecksville Reservations, I have yet to see it in the lower Rocky River valley.
