hydrangea and wisteria - both have varied flower colors. Both are also seen in Old Southern landscapes. Hydrangea like rich damp soil with filtered sun. Wisteria will seek out light and do well in full sun.
Coral Bean - The red seeds of Coral Bean (Erythrina herbacea) remain nestled in their open pod. They are toxic to humans, and since they have persisted into the late Winter it seems likely that there are no animals there that eat them.
