About False Jasmine

False jasmine, or Carolina jessamine (Gelsemium sempervirens), is a native southeastern U.S. vine and South Carolina's state flower. Climbs to 20 ft with fragrant yellow spring flowers that attract butterflies. Evergreen winter foliage. Hardy in zones 7–9—perfect for low-maintenance southern gardens.

Care Steps

Step 1: Plant in Full Sun

Full sun maximizes flowering and growth. Rich, fertile, well-drained soil. Space 3+ ft apart.

Step 2: Mulch

Apply 2-inch organic mulch after planting. Keep 2 inches from base for air circulation and to prevent crown rot.

Step 3: Water for Establishment

Weekly for first two months, then every 10 days. Water early morning to reduce disease risk.

Step 4: Fertilize Monthly (Spring/Summer)

Use balanced 10-10-10 NPK per label. Avoid over-fertilizing—reduces flowering.

Step 5: Prune After Flowering

Prune immediately post-bloom for compact habit, health, and appearance. Remove top-heavy, leggy, or damaged growth.
