Panda plant
Kalanchoe tomentosa
In other languages: Kalanchoë (Nederlands) · Plante panda (Français)
The panda plant comes from Madagascar, where it grows in dry, rocky places. It is a small, upright succulent with thick, oval leaves completely covered in silvery grey, felty hairs. The leaf edges and tips are marked with brown to rusty red, as if someone had touched them up with a felt-tip pen. Growers like it because it is soft to the touch, needs little water and is easy to propagate. A well-known cultivar is ‘Chocolate Soldier’, with dark brown edges. Indoors it rarely flowers, but the leaves alone make it decorative enough.
Caution: Toxic to cats and dogs: like other kalanchoes it contains substances that cause vomiting and diarrhoea if nibbled and, in large amounts, can affect the heart. Keep it out of reach of pets and young children and clear away fallen or cut leaves.

Identify
Panda plant: how do you recognise it?
- Habit
- Upright, somewhat branching succulent; 30–50 cm tall indoors and up to 30 cm wide.
- Leaves
- Thick, oval to oblong, 3–6 cm long, densely covered in silvery grey felty hairs; edge and tip dotted with brown to reddish brown.
- Stem
- Fleshy and also felty; it becomes slightly woody at the base with age.
- Flowering
- Indoors it rarely or never flowers; it is grown for its leaves.
- Roots
- Fine and shallow; they cannot stand wet feet.
Plants: March–April · Pruning: April
In your garden
Why grow it?
- Velvety, silvery grey leaves with a brown edge: a striking texture among other succulents.
- Very little work: a good drink of water now and then is enough.
- Ideal for a sunny windowsill, where many other houseplants scorch.
- Stays compact and fits on the smallest windowsill.
- Easy to propagate from a leaf or a stem cutting.
Panda plant: where does it grow best?
- Sunny: a south- or west-facing window is ideal. In a dark spot it becomes leggy and loses its compact shape.
- Room temperature in summer; preferably cooler in winter, 10–15 °C, but never below 10 °C.
- Dry room air is no problem.
- In summer it can go outside in a sunny, sheltered spot out of the rain; bring it in before nights drop below 10 °C.
- Out of reach of cats and dogs.

Goes well with
- Aloe: Also a succulent that loves sun and little water.
- Echeveria: Grey and blue-green rosettes for the same sunny windowsill.
- Jade plant: From the same family, with glossy, fleshy leaves.
- Cacti: The same compost and the same watering rhythm.
Maintenance
Panda plant: when and how to plant it?
Plant in March–April.
- Repot in March–April, every 2–3 years, when the pot is full of roots.
- Choose a terracotta pot with a drainage hole, only slightly larger than the root ball.
- Use cactus and succulent compost, or ordinary potting compost mixed with a third coarse sand or perlite.
- Set the plant at the same depth as before and firm lightly.
- Wait a week after repotting before watering, so damaged roots can heal.
Care
- Water
- Only water when the compost is completely dry, and then thoroughly. Water the compost, not the felty leaves. In winter, once a month at most.
- Feeding
- From April to September, cactus and succulent feed at half strength once a month.
- Light
- Turn the pot now and then so it does not lean towards the light.
- Leaves
- Brush off dust with a soft paintbrush; do not mist or wipe with a wet cloth.
- Repotting
- Every 2–3 years in spring, into a pot only slightly larger.
Tip: Give it as much sun as possible and only water when the compost is completely dry. Water the compost, not the felty leaves: that keeps them looking good and stops the plant rotting.
Panda plant: when to prune it?
Pruning months: April.
When: Hardly needed. In April you can shorten a leggy plant.
How:
- Cut overlong stems back to just above a leaf; new side shoots grow from there.
- Pinch out the tips of young plants for bushier growth.
- Use the removed tips as cuttings.
- Remove dried-out lower leaves.
Caution: Wash your hands after pruning and clear away the cut pieces: they are toxic to pets.
Propagation
- Leaf cuttings
- From April to July, snap off a healthy leaf, let it dry for a few days and lay it on dry cactus compost. Only add a little water once the first roots appear; after a few weeks new plantlets form at the base of the leaf.
- Tip cuttings
- Cut off a tip of 5–10 cm, let the cut dry for 1–2 days and push it into slightly moist cactus compost. In a warm, bright spot it roots within a few weeks.
Panda plant: how does it get through the winter?
- Indoors all year, except perhaps in summer: it does not tolerate frost and suffers below 10 °C.
- A bright, cool spot (10–15 °C) is ideal.
- Water very sparingly: once a month or less, just enough to stop the leaves wrinkling.
- No feeding from October to March.
Diseases and pests
- Rot: A soft, black stem base or glassy leaves from too much water or cold, wet compost. Water less; take healthy tips as cuttings if the base has rotted.
- Legginess: Long, floppy stems with large gaps between the leaves: too little light. Move it somewhere sunnier and cut back.
- Mealybug: White, woolly tufts between the leaves. Remove them with a cotton bud dipped in a little alcohol.
- Leaf marks: Water left on the felty leaves causes ugly marks. Always water the compost.
- Wrinkled leaves: A sign of prolonged drought; give it a good soak.
Through the year
- January: Cool and bright. Very little water.
- March: Repot. Gradually start watering a little more.
- April: Repot or shorten. Start feeding monthly again. Take cuttings.
- May: Feed. Take cuttings.
- June: Move outside to a sunny, sheltered spot if you like. Feed.
- July: Feed. Only water when the compost is dry.
- August: Feed.
- September: Last feed of the year. Bring in before nights drop below 10 °C.
- October: Water less. Move to a bright, cool spot.
- December: Rest. Very little water.
Use
Edible and useful
Not edible. All parts of kalanchoe are poisonous: they contain bufadienolides, compounds that, like those of foxglove, act on the heart. In cats and dogs, chewing it causes drooling, vomiting and diarrhoea, and in larger amounts a slow or irregular heartbeat; rabbits, rodents and birds are sensitive to it too. Kalanchoes often stand on the windowsill or the coffee table, within reach of animals and children: put them higher up or in a room they do not go into, and clear up fallen or trimmed leaves. Call your vet if an animal has eaten some. If any is swallowed, call a poison centre (in Belgium 070 245 245) or your doctor at once.
You and this species
Did you know?
- The felty hairs reflect sunlight and reduce evaporation: that is how it survives the dry seasons in its native land.
- It belongs to the stonecrop family, like the jade plant, the echeveria and the biting stonecrop of the garden.
- The species name tomentosa means ‘densely felted with hairs’, after the thick hairs on its leaves and stems.
