I know that D. binata is generally winter hardy for the UK, and die back to almost nothing, only to grow from the roots in the spring. But is that the case for all forms?

I have had success with most so far, leaving them in an unheated greenhouse over winter. The one I'm a bit wary of is D. binata var. multifida f. extrema! Is it truely UK winter hardy? Will it survive in my unheated GH? Will it benefit from a winter dormancy?

Last year it died back from a cold shock, so I brought it indoors, and it grew back beautifully, if not a bit spindly!

I had mine at an unheated window sill, which meant that temps were in the 40's & 50's for most of the winter. I get the impression that they don't take the cold quite as well as the straight up binata, which I had in the attic, where temps were in the 30's & 40's. Here are old and blurry pictures:

Thanks Jim! I guess I'll probably be bringing it in again this winter, then.

Thanks Sheila!

Is that the case for extrema only, or should the multifidas also be brought in?


Sorry!

Marston Dragon too!   I'm gonna run out of room in the kitchen!

Many thanks Sheila!
