Is it dead
I have a P. caerulea on my deck in a container from last summer. It completely died down over the winter and it hasnt started budding , no green anywhere. My clematis's are growing great but not the Passiflora. I live in south west B.C Canada our winters are relativly mild so I thought it would be ok . How do I know if its dead ? I really hope it isnt because its my very favorite.
