Growth Rate

Crinkle leaf is a slow-growing plant with small, thick leaves that feature a distinctive wavy edge. It can take more than a few hours for the plant to mature.

Flowering

Your crinkle leaf plant will flower over the spring or summer months and produce lovely reddish-white flowers that will grow on a tall stem from the main plant.

Watering and Feeding

While you need to wait for the soil to dry during all seasons, just water your plant once or twice during the entire cold season. Fertilize monthly in the spring and summer with a liquid fertilizer.

Soil

Since standard potting mixes are too dense for Adromischus Cristatus, a blend made especially for cacti and succulents is best for these plants.

Hardiness

While hardy down to freezing temperatures of 0°C, avoid exposure to frost. Adromischus Cristatus is hardy to USDA hardiness zone 10.

Light

While they can tolerate partial shade, crinkle leaf plants prefer full sun, meaning at least six hours of direct sunlight. You can also use artificial growing light.

Propagation

Propagation is possible with seeds or leaf cuttings. The preferred time for sowing seeds is between February and March. Remember that the seeding method can be slightly hard to perform.
