About This Plant

Delosperma lehmannii, commonly called Lehmann's Ice Plant, is native to the arid coastal and semi-desert regions of the Eastern Cape and KwaZulu-Natal in South Africa. In spring and summer it produces vivid daisy-like flowers in bright pink, yellow, or purple depending on light conditions. It is a true drought-tolerant with virtually no maintenance.

The glistening leaves and vivid daisy flowers are its two defining qualities. The crystalline texture of the leaves is caused by specialised epidermal cells that reflect light, giving the plant a shimmering appearance in direct sun. When blooms appear in spring and summer, the small but vivid daisy-like flowers completely cover the rosettes.

Not listed by the ASPCA, but keep it out of reach of pets as a precaution. Delosperma is not on the ASPCA confirmed toxic or non-toxic plant list. Multiple sources describe it as generally non-toxic, but without a confirmed ASPCA listing, keep it out of reach of pets and small children as a precaution.

Full sun is non-negotiable for flowers and compact growth. Without adequate direct light the rosettes become loose and elongated and flowering stops entirely. In lower light it stays green and alive but the compact geometric rosette shape and the flowers both require a south-facing window with at least four to six hours of direct light daily.

Winter Dormancy

Delosperma lehmannii enters true dormancy from around October through February in Canadian conditions. During dormancy it stops growing and needs almost no water. Water just once every four to six weeks with a minimal amount. Do not fertilize.

Toxicity

Not on the ASPCA confirmed toxic or non-toxic plant list. Multiple plant care sources describe Delosperma as generally non-toxic. Until confirmed either way, keep it out of reach of pets and small children as a precaution.

Pests

Mealybugs are the most common pest, hiding in the tight junctions between the triangular leaves in each rosette. Root mealybugs can also affect the roots in overly moist conditions. Scale insects occasionally appear on the low spreading stems.

Other Plants You Might Like

Not sure this is the right fit? Here are three other plants our Canadian customers love. All ship across Canada and thrive in Canadian homes.

Living Stone Lithops. Desert geometry, different form.

For another South African desert succulent with a similarly unusual compact geometry and very low water needs, the Living Stone Lithops mimics pebbles and has the same south-facing windowsill requirements.

Aloe Pheasant Breast. Full sun and sculptural.

For another full-sun succulent for a south-facing Canadian windowsill that also handles near-neglect in winter, the Aloe Pheasant Breast has bold white-striped triangular leaves and a strong architectural presence.

String of Pearls. Trailing and low-water.

For a very different low-water succulent that trails over a shelf or hanging basket, the String of Pearls has spherical bead-like leaves on long trailing vines and the same south-facing windowsill requirements.

Common Questions

How often should I water the Delosperma Lehmannii?

In spring and summer, water when the soil is completely dry, roughly every two to three weeks. In Canadian winter dormancy from October to February, once every four to six weeks with a small amount. This plant is killed far more often by overwatering than by drought. Our indoor plant watering guide shows how to check soil moisture correctly.

Why is my Ice Plant not flowering?

Insufficient direct light is almost always the cause. Delosperma lehmannii flowers only in strong direct sun. If it is on an east-facing or north-facing windowsill, move it to a south-facing window. Also ensure it is getting the brief cooler, drier period of winter dormancy rather than being kept uniformly warm and watered year-round. The contrast between seasons triggers spring flowering. Read our guide to light requirements for indoor plants for more.

Is the Delosperma Lehmannii safe for pets?

It is not listed in the ASPCA confirmed toxic or non-toxic database. Multiple sources describe it as generally non-toxic. As a precaution, keep it out of reach of pets and small children until confirmed either way.

Why are the rosettes becoming loose or leggy?

Loose, elongated rosettes that lose their tight triangular geometry are caused by insufficient direct light. The plant is stretching toward more light. Move it to a south-facing windowsill with at least four to six hours of direct sun daily. Compact tight rosettes are only achieved in full direct sun.

Will it survive a Canadian winter indoors?

Yes, very easily. It goes into true dormancy and needs almost no water. Keep it in your sunniest south-facing window, above 10 degrees C, and water only once every four to six weeks. The dry air in Canadian homes during the heating season suits it perfectly. Read our tips on keeping plants alive in winter for more.

Good to Know

Sun: Full direct sun

Needs at least four to six hours of direct sun daily. A south-facing windowsill is the only suitable year-round position in a Canadian home. Without full direct sun, the rosettes loosen and flowers do not appear.

Light: Bright direct

A south-facing window is essential. Keep it as close to the glass as possible. From October to February in Canada, the reduced light causes dormancy, which is normal and healthy. The plant does not need supplemental lighting.

Water: When completely dry, barely in winter

Water only when the soil is completely dry. Every two to three weeks in spring and summer. Every four to six weeks in Canadian winter dormancy. Never leave it in standing water. This plant tolerates months of complete drought in dormancy.

Humidity: Low

Thrives in the dry air of forced-air heated Canadian homes. No misting, no humidifier. This is one of the best plants for rooms that get very dry in winter.

Pet Friendly: Caution

Not listed in the ASPCA confirmed toxic or non-toxic database. Generally described as non-toxic by multiple sources but not confirmed. Keep out of reach of pets and small children as a precaution.

Pro Tip

The natural cycle of a Canadian home from November to February, shorter days and lower indoor light levels, mimics the dry-season dormancy this plant experiences in South Africa. Do not fight this. Let the plant slow down, reduce watering to near-zero, and leave it in the sunniest window.
