Wide open late season yellow flowers have 4 thick petals or tepals, with purple stamens — very lovely against pale green deeply cut leaves. Petal tips recurve slightly like the toe of an Indian slipper and later silky seed heads expand the season of interest on this vine that climbs to 20' or more. Deciduous.
Minimum temperature: -20° F
