Crassula mesembryanthemoides

Crassula mesembryanthemoides has a name that might cause frequent mistakes in spelling. Instead, you can refer to it by its nickname “Crassula Moon Glow”. This shrubby-looking succulent challenges the notion of beauty in the eyes of the beholder because plant hobbyists and horticulturists adore it for the bizarre appearance that gives it a somewhat peculiar appeal.  

Crassula Moon Glow is easily identified by its banana-shaped, bright-green leaves that are engulfed in finely-textured, white hairs. The fleshy leaves grow in pairs and sit on top of woody stems that are likewise covered in soft hairs. As the stems age, their color changes to reddish-brown. 

This is a small succulent and Crassula Moon Glow will only reach a maximum height of 16-inches (40.64cm) and about the same in terms of width. The leaves measure approximately half-an-inch long or slightly over a centimeter.

In the fall and winter months, Crassula mesembryanthemoides will bloom small, bell-shaped, off-white, or cream-colored flowers on the tips of its branches. 

Crassula mesembryanthemoides is a member of the Crassulaceae family and is native to the Eastern Cape regions of South Africa, the Karoo, and the Valley Bushveld.

How to Grow and Care for Crassula Mesembryanthemoides

Crassula mesembryanthemoides plant

It doesn’t matter if you’re a long-time horticulturist or a first-timer. Crassula mesembryanthemoides is a wonderful choice because this charming succulent is easy to grow and care for.

You can plant Crassula Moon Glow in the outdoor garden or have it as an indoor succulent to add life and color to your home.

Keep in mind that this isn’t a cold-hardy succulent. If the temperature in your region drops below 30° F ( -1.1° C), it would be best to plant Crassula mesembryanthemoides in a pot that can be moved indoors.


Crassula Moon Glow prefers partial to full sunlight. As part of your outdoor succulent garden, place Crassula Moon Glow in a location that gets up to 6 hours of partial sunlight every day.

Avoid putting Crassula mesembryanthemoides in locations that are exposed to the full rays of the afternoon sun. If this isn’t possible, make sure Crassula is placed behind taller plants that can give it partial shade.

As an indoor succulent, place Crassula Moon Glow near a window that gets 4 to 6 hours of partial sunlight. If the available locations do not provide enough sunlight, put Crassula under a Grow Light for up to 6 hours daily.

If the succulent doesn’t receive enough sunlight, its leaves will stretch out and wither away. This phenomenon is called etiolation where the leaves appear to be reaching out for sunlight.


Crassula mesembryanthemoides succulent

Busy people love succulent plants because they don’t need much care. It can be said that neglect is better than fussing over a succulent. Crassula mesembryanthemoides will be perfectly fine if you don’t water them for over a week.

Before giving the plant water, make sure the soil is 100% dry. Watering the soil while it still carries moisture will lead to root rot.

Checking the soil’s level of dryness is easy. All you have to do is to insert a stick an inch deep into the topsoil. Pull the stick out and if its end feels dry to the touch, prepare the soil for a thorough soaking.

An important tip to remember is to water the soil and not the plant. If you water the plant, its leaves and stems will remain moist for a long time. Water the soil directly and get it drenched.

Pot and Soil

A pot that’s made of unglazed ceramic or terracotta is the best choice for Crassula mesembryanthemoides. These materials help moisture escape from the soil faster than other types of pots. It’s very important that the pot has drainage at the bottom.

The best choice of soil for Crassula Moon Glow is one that has good aeration and water filtering properties. Sandy soil, cactus soil, and a commercially available mix of succulent soil are all good choices.

You can add filtering ingredients such as perlite, pumice, coarse sand, and lava rocks to further improve the soil’s level of drainage.
