thunbergia grandiflora over-winter in north
From a little plant from Logee's bought this spring I now have a huge vine on my patio only now starting to flower. I don't have a greenhouse and not even many good sunny windows but was wondering if there is a way to over-winter this. I am hoping maybe I could force it into dormancy (by letting a frost hit it) and then cut it back and stick it in my cool basement over-winter. Does anyone know if this would work? It works for many of my tropicals.
