Blue jasmine is a semi-woody, perennial, climbing or spreading, twining vine in the buttercup family (Ranunculaceae) native to the central and southeastern United States. It can reach 6 to 10 feet high and 3 to 6 feet wide. The species epithet is a Latin word meaning “tightly curled” and refers to the curling, undulating margins of the sepals. This plant will flower best in full sun but will tolerate partial shade. Be sure to provide it with acidic soil and consistent moisture like it has in its native habitat is swamps and floodplains. Mulch around the plant to help keep the roots cool and moist. Showy, fragrant flowers bloom in spring and again in fall with possible periodic blooms during the summer. The vine is heat tolerant and usually dies back to the ground in winter (Type 3). It is less damaged by deer than other clematis and is resistant to black walnut and rabbits. Blue jasmine can either climb a trellis, fence, wall, or arbor or be unsupported as a ground cover. It requires consistently moist soil, so consider planting near water gardens, rain gardens, or streams. Butterflies, bees and other insects are attracted to the flower, making it a good addition to butterfly, pollinator, and native gardens.
