A marbled succulent

Kalanchoe marmorata, sometimes called penwiper, is a succulent perennial in the Crassulaceae family. It carries broad, toothed, glaucous leaves marked with purple mottling, and in season sends up loose sprays of white or pinkish tubular flowers.

Roots in East Africa

This species was first described by Baker in 1892 and comes from a wide swathe of Africa, native from Eritrea and Ethiopia down through Kenya, Uganda, Rwanda and Tanzania, with outposts in Somalia, Sudan and DR Congo. It grows there as a succulent subshrub in seasonally dry tropical habitats, and has long been used locally as a medicine.

Sun, sparing water, feeding

Give it full light with good ventilation, ideally under glass, in a peat-free, loam-based mix sharpened with grit or sand. Water moderately through the growing season and cut right back in winter, since it is far more likely to suffer from excess moisture than from drought. During spring and summer a balanced liquid feed two or three times supports steady growth.

Cuttings, offsets, or seed

The RHS notes this species can be raised from seed sown at 19–21°C in early spring or from offsets. More broadly for kalanchoe, stem cuttings and offsets root readily, usually within fifteen to twenty days, once the cut end is left to callous over for a day or so before going into a free-draining succulent mix. Bright indirect light and light watering help the new roots establish before the cutting is treated like a mature plant.

Marbled, textured foliage

The obovate leaves are toothed along their edges, glaucous in tone, and marbled with purple, reaching up to 20cm long. Flowers appear as panicles of slender white or pink tubes opening into spreading lobes up to 25mm across, and the plant keeps a bushy, evergreen habit staying under half a metre in height and spread.

Watch for sap feeders

Mealybugs and aphids are the pests most likely to trouble this plant, generally showing up as small clusters on stems and leaf joints.

Mildew and rust risk

Powdery mildews and a rust disease are the main problems flagged for this species, so good airflow and avoiding overly damp, still conditions are worth keeping in mind.

Low upkeep, no pruning

This is a low-maintenance plant suited to pots and patios, and it needs no routine pruning. Its main cultivation demands are the right light, a gritty well-drained mix, and restrained winter watering.

ToxicityAuthoritative · species

Toxic to cats & dogs

Kalanchoe (Crassulaceae) contains cardiac bufadienolide glycosides toxic to animals. This is where toxicity lives: every cultivar of this species inherits it and none can override it.
