Gardeners' Notes:

The plant has grown well in my zone 5 garden, however it has not bloomed the desired color and, much to my surprise, has had very different colored blooms in the same year. This year it bloomed magenta in the summer and is now blooming deep purple flowers for fall. I really wanted the deep red on the picture (and the name) for this bed.

I am in Zone 3B in Western Canada. A and C group clematis do very well here.This clematis is now 3 years old and gives a wonderful display. It is planted against a lattice that is exposed on both sides.

We haven't been all that happy with the Cardinal - in our experience it tends to wilt frequently and is not particularly vigorous. This may be due in part to our garden being small and crammed but other cultivars have done far better.
