Strobilanthes is a large genus and some of the species are moderately hardy. Unfortunately, that leaves the rest.
Information is quite limited so distinguishing the hardy from the tender is difficult. The easiest way it to buy an
unknown species and give it a try.
Strobilanthes anisophylla is hardy in New Zealand and it has good enough foliage to be worth a try.
The leaves were its downfall. It produced very dense growth and rapidly filled the pot with root.
I was keen to keep it under cover through the winter so I put off repotting it until the spring, by which time
it had dried out and died. I still don't know how hardy it would be (though it seems to have slipped off
nursery lists) and if I see another I will try again.
