Jade Necklace, Jade Necklace Plant, Jade Necklace Vine, Chinese Pagoda, Worm Plant
Crassula rupestris subsp. marnieriana, also known as Crassula marnieriana, is a slow-growing succulent shrublet with slender decumbent branches densely covered with green leaves with red edges. The branches often root when touching the ground. Leaves are thick, fleshy, about 0.2 inches (0.5 cm) long and 0.25 inches (0.6 cm) wide, ovate with a much-rounded apex and bases of opposite leaves fused into a disc for at least half their length.
Flowers are small, star-shaped, and pink-tinged and appear in terminal clusters in winter.
USDA hardiness zones 9b to 11b: from 25 °F (−3.9 °C) to 50 °F (+10 °C).
How to Grow and Care
Crassulas are easy to grow but susceptible to mealybugs and fungal diseases. As with all succulents, overwatering is sure to be fatal, so err on the side of too dry rather than too wet. Never let your plant sit in water. If you water from beneath by letting the plant sit in a saucer of water, make sure to pour off any excess water after a few minutes.
These succulents are generally started by division, offsets, or leaf cuttings. Crassulas can be easily propagated from a single leaf. Sprout leaves by placing them into a potting mix for succulents, then covering the dish until they sprout.
Repot as needed, preferably during the warm season. To repot your Crassula, ensure the soil is dry before repotting, then gently remove the pot. Knock away the old soil from the roots, removing any rotted or dead roots. Treat any cuts with a fungicide. Place the plant in its new pot and backfill it with potting soil, spreading the roots out as you repot. Leave the plant dry for a week or so, then begin to water lightly to reduce the risk of root rot.
