Gardeners' Notes:

Positive Clary On Jan 11, 2010, Clary from Lewisburg, PA (Zone 6b) wrote:

A more delicate ipomoea, both in appearance and performance - slow to leaf and bloom and not as large as other varieties. The unusual leaves and flowers make this vine worth growing, but if you're looking for full coverage of a structure, interplant it with other vines.

Beautiful flower. I also like the mottled coloring of the leaves.
