Common problems
Overwatering can lead to root rot. Insufficient sunlight may cause leggy growth. Occasionally, pests like aphids or mealybugs may appear but are usually easy to manage.
Uses
Used mainly as an ornamental ground cover in gardens and rockeries. Its drought tolerance makes it suitable for xeriscaping.
Notes
Prune occasionally to maintain shape and remove any dead stems. Repotting is rarely needed due to slow root growth. Protect from frost as it is sensitive to cold temperatures.
