With stems that can exceed 20 feet in length, Carolina jessamine (Gelsemium sempervirens) climbs over anything it can twine its wiry stem around. Plant it on trellises and arbors, along fences or under trees with loose canopies.
The glossy leaves stay green all year, providing dense coverage for the supporting structure. Carolina jessamine vines are covered with clusters of fragrant, yellow flowers in late winter and spring.
The flowers are followed by seed capsules that ripen slowly over the remainder of the season. If you want to collect a few seeds to start new plants, pick the capsules in fall after the seeds inside have turned brown.
Air dry them for three or four days and then remove the seeds. They are easy to start indoors in late winter or outdoors in late spring when the soil is thoroughly warm.
