Special Attributes

Jasmine Duet® is a combination of two species of magnificent climbing vines: Gelsemium rankinii and Gelsemium sempervirens, both of which are jasmines, also called Jessamine. Duet® is prized for its abundant and spectacular display of fragrant, bright yellow flowers in late winter into spring and again in fall. It is evergreen in USDA Zone 8a but may be semi-evergreen to deciduous in zones further north. Suitable for trellis, arbor, fences and walls, or as a groundcover. Semi-evergreen in mild-winter regions. is unique hybrid that produces its abundance of blooms in late winter to early spring and then again in fall! Its bright yellow, sweetly fragrant, funnel-shaped blooms contrast nicely with the shiny, dark green evergreen leaves that cover its dense, twining stems.

Landscape & Garden Uses

Growing 12 feet or more in height or length, and 2 to 4 feet wide, Jasmine Duet is ideal for use to climb along the tops of fences or over arbors and any other structure that provides support, such as a trellis, post or mailbox. It can also be useful as a ground cover for slopes or banks or to climb into smaller trees where early flowering is especially noticeable. 

Spacing:  3-6' apart on fences

Cultural Preferences

Jasmine Duet is very easy to grow. It tolerates a wide range of soils, even somewhat boggy soils, however is also exceptionally drought tolerant. It prefers a moist, well-drained soil of average fertility. We have it growing in sunny and partially shaded sites and it does equally as well in both exposures.
