How frost hardy are Cobaea David?
I've cut mine down, but left the roots in place.

It is fully hardy down to around minus 3C.

How curious. I always thought they were half hardy, being a mexican
full sun loving plant and all that. Is it the scandens you are
referring to or is there another one? I ask you that because when Mr
Forthegills once called it an half hardy annual on its packet, my
father in law just took the whole lot out in november.
