Kalanchoe tomentosa, also known as the panda plant, pussy ears, or chocolate soldier,[2][3] is a species of succulent plant in the family Crassulaceae. A native of Madagascar, it is widely cultivated as an ornamental plant due to its distinctive velvety, silver-green leaves with chocolate-brown markings. It has received the Royal Horticultural Society's Award of Garden Merit.[3]

Description
editKalanchoe tomentosa is a slow-growing, evergreen, semi-woody perennial succulent subshrub with an erect growth form.[2][4] It can reach a height of 0.4 to 1 m (1.3 to 3.3 ft) and a spread of up to 0.9 m (3.0 ft),[2][3] though it typically remains smaller in cultivation, around 30 to 50 cm (12 to 20 in).[5] Young roots are red with white tips.[2]
The most distinctive feature of the plant is its leaves, which are thick, fleshy, and oval-shaped, typically measuring up to 9 cm (3.5 in) in length.[3] The leaves are arranged opposite or in a loose rosette and are densely covered with fine, silvery-white to grayish hairs (trichomes), giving them a velvety or felt-like texture.[2][4] The leaf margins are scalloped and tipped with a series of dark brown to rusty-red spots or a continuous chocolate-brown rim, a characteristic that inspired the common name "chocolate soldier."[2][5] In mature plants, young leaves appear whitish and erect, while older leaves become lighter green, less fuzzy, and more horizontal.[2]
The flowers are small, tubular, and bell-shaped, measuring about 1 cm (0.39 in) in length, and are borne in panicles atop erect stalks that can reach up to 45 cm (18 in) in height.[3][4] Flower colors range from greenish-white to yellow-green, sometimes with brown or purple petal tips.[2][4] In their natural habitat, they bloom between March and June; however, indoor plants rarely flower.[5][2] The fruit is a dry capsule containing numerous small seeds.[2]
Taxonomy
editThe species was first described by the British botanist John Gilbert Baker in 1882 in the Journal of Botany, British and Foreign, based on collections made from east-central Madagascar.[1][6] The specific epithet tomentosa is derived from the Latin tomentosus, meaning "covered with dense, matted hairs,"[4][5] in reference to the plant's velvety foliage. A heterotypic synonym, Bryophyllum triangulare Blanco (1845), has been rejected as a name to be rejected.[1]
In a 2023 revision, Smith provided an amplified description of the species and designated an epitype to clarify the application of the name.[6] The species is highly variable in leaf shape, hair density, and margin coloration, which has led to the description of numerous cultivars.[6]
Distribution and habitat
editCultivars
editNumerous cultivars have been developed, selected for variations in leaf size, shape, and coloration:[5][4]
- 'Chocolate Soldier' – The most common cultivar, featuring narrower, pale-colored leaves with a more uniform and thicker dark chocolate-brown margin. It is reportedly faster-growing and has a clumping habit.[4][7]
- 'Golden Girl' – Characterized by golden-yellow, fuzzy leaves that become more vibrant with increased sunlight exposure. It produces clusters of golden trumpet-shaped flowers.[8]
- 'Teddy Bear' – Features rounder, chocolate-brown leaves densely covered with fuzz and almost black markings at the tips.[4]
- 'Cinnamon' – Has long, oval-shaped russet leaves that appear almost black when grown in full sun.[4]
- 'Nigra' – Exhibits extremely dark brown to nearly black leaf margins, which can be dotted or continuous.[5]
- 'Rubra' – Displays a reddish hue, particularly pronounced along the leaf edges, with a golden-red shimmer.[5]
- 'Black Tie' – Another dark-margined selection.[9]
Cultivation
editKalanchoe tomentosa is widely cultivated as a houseplant and in rock gardens, container gardens, and succulent gardens in warm climates. It is prized for its attractive, tactile foliage and low-maintenance requirements.[2][4]
Growing conditions
editThe plant thrives in bright, indirect sunlight, though it can tolerate some direct sun; however, intense afternoon sun may cause leaf burn.[4][10] Insufficient light results in leggy, elongated growth.[4]
A well-draining potting mix, such as a cactus or succulent mix, is essential to prevent root rot.[2][3] The plant prefers temperatures between 15 and 23 °C (59 and 73 °F) and is not frost-hardy; it should be grown in USDA hardiness zones 9–11 or brought indoors during winter.[4][11]
Watering and feeding
editWater should be applied thoroughly but infrequently, allowing the top 2.5 cm (0.98 in) of soil to dry out completely between waterings.[2] Overwatering is a common cause of plant failure, leading to root rot and mushy leaves.[4] During the winter dormancy period, watering should be reduced significantly.[3] Fertilization is generally minimal; a half-strength balanced liquid fertilizer can be applied monthly during the growing season.[2]
Propagation
editPests and diseases
editCommon pests include mealybugs, aphids, and spider mites.[4][3] Overwatering can lead to root rot, and high humidity may promote powdery mildew or rust.[3] Shriveled or wrinkled leaves typically indicate underwatering, while yellow or mushy leaves suggest overwatering.[4]
Toxicity
editCommon names
editThe plant is known by many common names across different languages and regions:[12]
- English: Panda plant, pussy ears, chocolate soldier, velvet leaf kalanchoe, plush plant, teddy bear cactus, cocoon plant[10]
- Chinese: 月兔耳 (yuè tù ěr, "moon rabbit ear") or 褐斑伽蓝 (hè bān qié lán)[12]
- Dutch: Pandaplant[12]
- Indonesian: Kaktus panda[12]
- Polish: Żyworódka omszona[12]
- Ukrainian: Каланхое повстисте[12]
Uses
editThe plant is primarily grown as an ornamental for its striking foliage. It is suitable for indoor containers, hanging baskets, rooftop gardens, and rockeries.[2] In its native Madagascar, there is a popular belief that when a panda plant flowers for someone, it is an indication of richness and prosperity for their household.[7]
Conservation
editAs of 2026, Kalanchoe tomentosa has not been formally assessed for the IUCN Red List. However, it is listed as a species of "least concern" by the Angiosperm Extinction Risk Predictions project, though with low confidence.[1] The species is widely cultivated and not considered threatened in the wild, though habitat loss in Madagascar could impact wild populations.
