Kalanchoe tomentosa
| Light | Bright, indirect light to a few hours of gentle sun; more light keeps the fuzz dense and the leaf edges dark |
|---|---|
| Water | Sparingly; let the mix dry out fully between waterings, and keep nearly dry through the cool months |
| Soil | Gritty, fast-draining succulent mix (see Soil and potting mix) |
| Temperature | Warmth-loving; protect from frost, best kept above about 10 °C / USDA zones 9b–11 |
| Propagation | Leaf and stem cuttings (easy); see Propagation — cuttings |
| Toxicity | Toxic to cats and dogs if eaten (like most Kalanchoe); keep away from pets |
Kalanchoe tomentosa, widely known as the panda plant, is a soft, upright succulent from Madagascar prized for its thick, fuzzy silvery leaves edged with felted, chocolate-brown tips. The dense coat of fine hairs gives the whole plant a plush, almost animal-like feel that has earned it common names such as panda plant and pussy ears. It is one of the most forgiving and popular succulents for a bright windowsill, and a member of the large genus Kalanchoe in the stonecrop family Crassulaceae.
Description
Kalanchoe tomentosa grows as a small, branching shrublet that becomes gently woody and upright with age, in time reaching perhaps 30–45 cm tall in a pot. Its leaves are the main attraction: thick, spoon- to lance-shaped and arranged in loose rosettes toward the stem tips, each one densely covered in fine white to silvery hairs (the "tomentum" that gives the species its name). Along the upper edges of every leaf sit a row of felted teeth tipped in rich reddish- to chocolate-brown, and the amount of brown edging deepens with brighter light.
Like many Kalanchoe, mature plants can flower, but K. tomentosa is grown almost entirely for its foliage; blooms are infrequent in cultivation and modest — small, fuzzy, bell-shaped flowers held above the leaves — so most growers never see them and don't miss them.
Distribution and habitat
The species is endemic to Madagascar, where it grows on rocky, well-drained slopes in a warm, seasonally dry climate. Its dense felting is a classic adaptation to bright, exposed conditions, helping to reflect strong sun and reduce water loss from the leaf surface. In habitat it experiences a pronounced dry season, which is worth keeping in mind when deciding how often to water.
Cultivation
Kalanchoe tomentosa is an easygoing, beginner-friendly succulent, and the two things it really asks for are good light and restraint with the watering can. Give it the brightest spot you can short of harsh, unfiltered midday summer sun through glass — plenty of light keeps growth compact, the fuzz thick, and the leaf-edge markings dark. In too little light the plant stretches, the stems lengthen between leaves, and the colouring fades.
Grow it in a gritty, free-draining mix and water only when the soil has dried out completely, then soak it thoroughly and let it dry again. Through the cooler, darker months slow right down and keep the plant nearly dry, which prevents rot when growth has stalled. It resents cold and wet together, so keep it warm and protect it from frost; see Watering and Repotting for general technique. The felted leaves also dislike being wetted repeatedly — water at the roots rather than over the foliage to keep the coat clean and reduce the chance of marking.
Propagation
Panda plant is very easy to propagate vegetatively. Whole leaves laid or lightly set on the surface of a barely-moist gritty mix will often callous and produce plantlets at the base, and stem cuttings root readily once their cut ends have dried for a day or two. Warmth, bright light and a light touch with moisture give the best results — cuttings and leaves rot far more often from being kept wet than from being kept a little dry. See Propagation — cuttings and Propagation — leaves for full walkthroughs. Taking cuttings is also a handy way to restart a plant that has grown leggy and bare at the base.
Cultivars
A few selected forms circulate in the hobby, chosen mostly for leaf shape and colour. Chocolate Soldier is a widely grown form with narrower leaves and especially strong brown edging, while Golden Girl has a warmer, golden tone to the felt. Names in the trade are applied loosely, so plants sold under these labels can vary.
Common problems
- Rot — by far the commonest cause of loss, from overwatering, a slow-draining mix, or watering during cold weather; leaves and stems go soft and translucent.
- Etiolation — too little light stretches the stems, spaces out the leaves and dulls the brown edging, spoiling the compact look.
- Marked or grubby fuzz — water sitting on the felted leaves can leave spots or trap dust; keep water off the foliage.
- Pests — mealybugs love to hide in the leaf axils and among the hairs; watch also for aphids on any flower stalks. See Pests and diseases.
