- Description
-
Blue Jasmine is a clematis that is a semi-woody vine native to wet sites as swamps and flood plains of southeastern North America. The vine usually dies back to the ground in winter. Be sure to provide it with consistant moisture and fertiliztion in spring to support the rapid growth. Mulch around the plant to help keep the roots cool and moist. The blooms occur in the spring and again in the fall with possible periodic blooms during the summer.
It needs consistently moist soils, so consider planting near water gardens, rain gardens, streams, or in native plant gardens. It can either climb a trellis, fence, wall, or arbor or be unsupported as a ground cover.
Insects, Diseases, and Other Plant Problems: No serious problems. Wilt can sometimes be fatal.
