Gardeners' Notes:

Positive sladeofsky On Jan 16, 2015, sladeofsky from Louisville, KY (Zone 6b) wrote:

This lovely US native grows naturally in zones 6b to 9a, but it is probably hardy to 5a. It enjoys moist (not wet) soils. Increasingly it is being used to hybridize a plethora of lovely bell shaped clems for the garden. But the straight species is worth growing I it's own right. Although vigorous, it tends to be loose and sparse, leading some to refer to it as one of the "see-through vines." Although like all the American Clematis, there is variability in color, it tends to be white trimmed in blue. If you are interested in trying your own hand at breeding, this is one you should have. It is a leaner or scrambler, and a wonderful addition to roses, hydrangeas and can soften conifers and add a subtle splash of conifers. Just be careful not to plant it in a shrub that requires constant sheering, it is perfect to grow into shrubs that are pruned only once in Spring, before it emerges.

I bought this from a native plants nursery here in Florida, and got the medium blue type. The flowers are lovely, small and bell shaped with recurved petal tips, very decorative. It is more a sprawler than a climber, and it does prefer partial shade down here, woodland soil, and moisture. It will withstand occasional flooding but isn't happy about that. I wish I had a photo of its flowers. If you have the chance to grow this gentle beauty, take it!
