Cynanchum marnierianum, commonly called the Bundle of Sticks plant, is an unusual and highly architectural succulent vine from Madagascar. Known for its thin, jointed green stems that resemble a tangled mass of twigs, it grows with a trailing or cascading habit that makes it perfect for hanging planters, tall pots, or mounted displays. Despite its stark, leafless appearance, this is a living, photosynthetic plant that thrives on minimal care and rewards with slow, graceful growth.

This species belongs to the milkweed family (Apocynaceae) and, while foliage is minimal or absent, it will occasionally produce tiny star-shaped flowers under the right conditions.

Care Guide

• Light: Bright, filtered light to partial sun. Tolerates some direct morning sun but prefers protection from strong afternoon rays.

• Water: Allow soil to dry completely between waterings. Water sparingly, especially in winter.

• Humidity: Tolerates low humidity well. No additional misting or humidity is needed.

• Temperature: Prefers 65–85°F. Protect from cold drafts and avoid temperatures below 50°F.

• Soil: Use a sharply draining cactus or succulent mix with added pumice or perlite. Avoid moisture-retentive substrates.

• Fertilizer: Feed once monthly during spring and summer with a diluted cactus or low-nitrogen fertilizer. No feeding needed during winter.

Blooms

Under bright, warm conditions, Cynanchum marnierianum may produce tiny pale yellow to greenish-white flowers. Blooms typically appear during the growing season (late spring through summer) and are small and inconspicuous, but charming up close.

How to Grow Outdoors (San Francisco)

This species can be grown outdoors in a protected location during warm months. Choose a spot with bright, indirect light or filtered sun. Avoid full, hot sun exposure or excessive rain.
