Having grown up in Miami and only lived as far north as Atlanta, I can admit I know nothing of what my Northern friends call "real" winters–the kind that have you huddled indoors from December straight through St.
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.
