Strobilanthes rankanensis is one of those perennials that has been around a fair while but never been widely available for some reason - this deserves to be much more widely grown.  Strobilanthes do have a bit of a reputation of not being very hardy but this species has easily survived -16°C here, even re-shooting from 30-40cm up the stems that year.

It will try and retain it's leaves overwinter but cold weather will cause them to be dropped, especially if in a windy site.  The stems are usually retained and rather like a Fuchsia, it will sprout from ground level or higher in the spring.

Very pretty rich coloured flowers for many weeks (even months).
