La cultiver

Propagation
cuttings, seed
When to plant
spring, autumn
Overwintering
If you live in a cold climate, bring the container indoors before the first frost. Place it in a bright window and reduce watering significantly during the winter months.
In containers
It grows very well in containers, provided you use a pot with drainage holes and a minimum size of 12 inches in diameter.

Stem Cuttings

  1. Take a 4 to 6 inch cutting from a healthy, non-flowering stem.
  2. Remove the lower leaves and dip the cut end in rooting hormone.
  3. Plant the cutting in a well-draining potting mix.
  4. Keep the soil lightly moist and provide bright, indirect light until roots form.

Pair this plant with other drought-tolerant species that enjoy full sun to minimize maintenance needs.
