Other info. - This distinctive plant is found in only a few areas, mostly in east-central Missouri and north-central Kansas. Where it is found it can be locally fairly abundant. It is easy to recognize, being the only Clematis in the state without a vining habit. Over the winter, the leaves turn brown and slowly disintegrate, leaving behind the persistent lacy vasculature as well as the distinctive fruiting heads. The plant is a slow-growing but long-lived perennial. In Missouri it is a tracked species (S3 - vulnerable due to restricted range and relatively few populations).
