Crinkle Leaf Plant Care

Size and Growth

Adromischus cristatus is a low-growing plant with a typical height of about six inches. The green to gray leaves with tiny hairs grow from thick stems and form a loose rosette.

The cristatus variety produces flattened leaves and tends to appear crinkly, giving it the name crinkle leaf plant.

Other varieties, such as Adromischus cooperi, produce rounded leaves.

Flowering and Fragrance

The plant usually blooms in the spring but may bloom later depending on sunlight, soil, and temperature conditions.

Typically, if it receives more warmth during the winter, it has a late bloom.

The crinkle-leaf plant produces small tubular-shaped flowers. They are white with hints of red and don’t create a significant fragrance.

Light and Temperature

Crinkle Leaf Plant is typically grown indoors all year round in

It’s only suited for outdoor growth out in full sun or partial shade in the warmest of regions, such as USDA hardiness zone 9b to 10.

In cooler zones, the plant may be brought outdoors during the warmest parts of the summer but sheltered from direct sunlight.

When grown indoors, place the crinkle leaf plant in a well-lit area with bright light like a windowsill.

Avoid placing it in a south-facing window where it’s more likely to get exposed to brighter light.

Regular room temperature is recommended but the plant can handle cooler temperatures during the winter.

The recommended minimum temperature between December and February is 50° degrees Fahrenheit.

While the plant is best suited for growth indoors in most regions, stagnant air is not good for the plant.

Ensure that the room it is in has good circulation.

Watering and Feeding

Water the plant regularly throughout the active growing period. During the winter, water sparingly.

In fact, almost no water is needed between December and February.

Use diluted liquid fertilizer once per month during the spring and summer. Don’t feed the plant during the winter.

Soil and Transplanting

Use a porous well-draining soil or bagged cactus soil mix for Adromischus cristatus and other varieties within this genus.

An alternative option is to use regular potting soil combined with pumice and a little bit of sand.

There is no need to repot the plant each year unless it outgrows its container.

If it the leaves are spilling out over the edges of the pot, transplant to a slightly larger pot in the spring.

When transplanting, carefully remove the plant from the soil and shake the roots free.

Allow the plant to dry overnight and then set in fresh soil the next morning.

Maintenance and Grooming

No grooming is needed.
