For warm region gardeners, the appearance of Carolina jessamine’s sunny yellow blossoms is a sure sign that spring is just around the corner.
This native twining vine sends up many slender, wiry stems; if they don’t have a support to grow on, they’ll twine around each other and form a sprawling ground cover.
Carolina jessamine has glossy evergreen foliage that nicely sets off the fragrant, funnel shaped flowers. The fruits are small capsules which tend to go unnoticed. Carolina jessamine makes a refined cloak for trellises, pergolas and fences, or let it go wild in naturalized areas.
