Origin and distribution

Corpuscularia lehmannii is a succulent plant native to South Africa that has become popular in many different parts of the world, including the United States and Europe, due to its unusual and aesthetically pleasing appearance. These plants are often grown as potted plants, but they can also be found growing wild on cliffsides or on the edges of forests.

The species was first identified in 1836 when it was brought to England from South Africa by Johann Lehmann, a German botanist who had traveled around South Africa collecting specimens for Kew Gardens.

The scientific name of Corpuscularia lehmannii refers to him directly, delosperma refers to two seeds while lehmannii was named after his last name, Lehmann. This plant requires ample water and moderate sunlight exposure, although too much direct sunlight will burn it and prevent it from producing flowers.

Common names

Avoid getting water on its branches, as it could cause mildew growth. If you live in a warm climate, you can grow an ice plant inside of your home, providing bright sunlight and lower humidity levels. Overwatering is a common mistake that could kill your succulent, water when topsoil feels dry to touch.


Ice plant is not a very hungry little succulent, so it doesn’t need to be fertilized too often. Using slow-release fertilizer can provide all of its nutritional needs, but if you do use liquid fertilizer, follow directions and don’t overdo it.

The overuse of fertilizer will result in leaf tip burn and an unappealing appearance that doesn’t look healthy at all.


Corpuscularia lehmannii prefers to live in very cold climates. They are native to places like South Africa, Australia, and New Zealand, where it’s colder than 65 degrees year-round. If you want to keep an ice plant indoors, place it in a bright area near a south-facing window.

It will also need plenty of sun and water about every three days. Finally, place it in a container with ample drainage holes; these plants tend to rot if they sit in water for too long.


Corpuscularia lehmannii does best in a humid environment. If you’re growing it indoors and aren’t able to replicate its natural environment, be sure to mist your plant daily. It will also help keep it from getting spider mites, which can be problematic for succulents. You may also want to consider planting your succulent in soil instead of a potting medium, as these plants need extra moisture at all times.

The ideal humidity range for Corpuscularia lehmannii is between 40-60%. Remember that water changes the temperature of the air around it – so if you’re looking to create a warmer climate, make sure not to overwater.

As a rule of thumb, you can just snip any woody stems right above a leaf joint. But some gardeners like to pinch back shorter stems to encourage fuller growth and more flowers.

Simply nip offshoots at an angle so they don’t leave ugly stubs. Don’t be tempted to shear or saw off plants – it’s better to take two cuts than do more damage with one! If your clippings are small enough, use them as mulch for the next season’s container planting.

When to repot

Repot your ice plant succulent every two years in spring. Repotting too often can cause its roots to rot and can damage its growth and flowering ability.

When you do repot it, be sure to use a clean container, free of pests and diseases that might kill your plant or spread to other plants. Remember to prune any rotted roots when you repot it as well.

Dormancy/Winter rest

Corpuscularia lehmannii

As most succulents are native to warm, arid climates, they need to be coddled in winter. Move your plant(s) inside or under a porch or patio and allow it to go dormant until spring arrives.

If you live in a very cold region and want your plant to survive through winter, you may choose to bring it indoors in early fall before the temperature drops too low. However, don’t place it next to any heating vents or drafty windows as this can dry out the soil.

You may also use a humidity tray on top of pebbles with water as this will create condensation that will moisten the soil of the pot for several hours each day. Don’t forget to also water every week!

Pests and diseases

While ice plant succulents are typically hardy plants, they can still suffer from a few pests and diseases. Aphids, whiteflies, mealybugs, and scale insects can all wreak havoc on your succulents.

Monitor your plants for signs of these pests and treat them with insecticidal soap or horticultural oil. If that doesn’t work, bring in an experienced exterminator to rid your garden of these dangerous pests.

Likewise, you may want to consider planting sagebrush near your succulents to help ward off insects that might feed on the leaves. White salt also has shown promise as a possible defense against some pest infestations.

And if aphids become too much of a problem, you may be able to cut back their population by reducing watering as well as fertilizing less often during the summer months when they’re most active.
