Thought to ba chance hybrid between C. virginiana ans C. heracifolia. It looks nice in front and sprawling up hydrangeas.

A big plant that can be vigorous to a fault. The woody stems are fully hardy here (Boston Z6). This plant is virtually indestructible.

The ice-blue flowers begin in early August here, and continue well into September. They put on an excellent show, making up in numbers for their small size.

Unlike most clematis, it doesn't use its petioles to climb, just sprawls along the ground. It can form a dense, weed-smothering groundcover that way. Where nodes touch the ground, it will self-layer(root), producing new plants when the stem is severed from the parent.

It can be made to climb by tying the new growth to a support. I've forced it to climb 12' in a season that way.

Like most clematis, it holds onto its dead leaves and looks like a mare's nest all winter. I cut off the most offensive in the fall but wait till spring to do any hard pruning.

This is said to be a chance hybrid between C. tubulosa and C. virginiana.

I was attracted to this clematis because the leaves are very similar to another shrubby clematis that I have called Alan Bloom. It is a reliable performer and very unusual. Mrs. Robert Brydon was just planted this summer and it is already blooming. The flowers are a lovely pale blue color with big fluffy ivory colored tufts - very striking.
