Heterotis rotundifolia aka Pinklady
Taxonomy ID: 12177
Heterotis rotundifolia is a low plant from tropical Africa. It is a perennial, so it lives for years. It belongs to the Melastomataceae family. Useful Tropical Plants calls it Dissotis rotundifolia. That source lists Heterotis rotundifolia as another name for it. Its native range runs from Sierra Leone east to Ethiopia. It reaches south to Angola, Zimbabwe and Mozambique. Kew places it in the wet tropical biome, a broad climate zone. It grows wild, and people also grow it for show.
Kew classes this plant as a subshrub. Useful Tropical Plants calls it an herb whose stems lie on the ground. Some stems rise a little, then trail across the soil. The plant grows about 0.7 feet [0.2 metres] tall. Its stems often take root at their nodes, or joints. This low, spreading shape makes it useful as ground cover. The sources give no width for a full-grown plant. They give no details of its leaves, bark or fruit. Plants can bloom through the year, not just in one short season.
In the wild, it grows in wet parts of the forest zone. It favours new growth on land that people have cleared. Records include land left fallow for two or three years. It also grows on old farms and in palm plantations. Other sites include swamps, land by water and grassland. It grows at heights up to about 3,940 feet [1,200 metres]. In gardens, it likes moist soil and sun or part shade. The sources give no rating for cold or frost tolerance. They list seed as one way to grow new plants.
Gardeners use this plant as low cover in tropical sites. As ground cover, it also helps keep soil from washing away. Yet its spread can cause problems beyond the garden. It has escaped gardens in many tropical regions. In pastures and other sunny places, it can become a troublesome weed. Useful Tropical Plants warns against bringing it to places where it does not yet grow. People also gather wild plants for local use as medicine. Records note use of the leaves against worms in the gut. This does not prove the treatment or any dose is safe. The source lists no known food uses or hazards. This lack of reported harm does not prove safety for people or pets.

Where is Pinklady native to?
Heterotis rotundifolia is native to tropical West and Central Africa, ranging from Sierra Leone through Guinea, Cameroon, Gabon, the Congo Basin, and south to Angola, Zambia, and Zimbabwe. It also occurs naturally on Gulf of Guinea islands (Bioko, Príncipe, São Tomé). It has been widely introduced as an ornamental ground cover to Hawaii, the Caribbean, Central and South America, Pacific island groups, and parts of Asia.
How big does Pinklady get?
Pinklady is a low-growing, sprawling shrublet, typically reaching 20–40 cm in height but spreading much wider as stems trail and root at the nodes. In favourable tropical conditions growth can be rapid. The trailing habit makes it effective as ground cover.
What do Pinklady flowers look like?
Flowers are solitary with petals 1.5–2 cm long, ranging from pink to pale purple. Stems are pink to dark reddish. The genus Melastomataceae is typically insect-pollinated; the showy pink flowers attract pollinators. In tropical climates the plant may flower over an extended season.
Is Pinklady edible?
Young shoots are edible and used as a sorrel substitute. Leaves are used as a potherb and cooking spice in West African cuisine. Leaves and young stems are consumed as wild edible plants by rural communities in Northern Uganda; analysis showed no significant heavy-metal health risk at normal consumption levels. Gorillas in the native range also consume the young shoots.
Does Pinklady have medicinal uses?
Traditional uses in West and Central Africa include combining leaves with melegueta pepper seeds to treat cough, preparing leaves as an herbal tea, and applying heated leaves topically to wounds. In Liberia, the plant is used as a natural diuretic. These are folk medicinal uses; no peer-reviewed clinical evidence for efficacy was identified.
Can Pinklady be grown outdoors?
Pinklady is grown outdoors as a ground cover in tropical and subtropical gardens worldwide. It has naturalized in Hawaii, the Caribbean, parts of Australia, Malaysia, and various Pacific islands, demonstrating vigorous outdoor performance in warm climates. In cooler regions it should be brought under cover in winter. It can spread invasively via trailing rooting stems in frost-free areas, so garden placement should be considered carefully.
What other uses does Pinklady have?
Pinklady is widely planted as an ornamental ground cover in tropical and subtropical gardens globally. It is used as a spice in sauces in West Africa. Research has shown that its aerial root mucilage supports nitrogen-fixing microbiota, which may contribute to its vigour in nutrient-poor soils. Local wildlife, including gorillas, feed on the young shoots.
Are there different names or varieties of Pinklady?
Several synonyms exist in older literature: the most common is Dissotis rotundifolia, under which the plant is still sold in horticulture in some regions. Other synonyms include Melastoma plumosum, Heterotis plumosa, and Osbeckia rotundifolia (the basionym). The accepted name is Heterotis rotundifolia (Sm.) Jacq.-Fél.
How difficult is Pinklady to grow?
Pinklady is an easy-care plant in tropical and subtropical climates. It tolerates a range of light conditions and spreads vigorously in warm, moist environments, requiring minimal intervention once established. Its main requirement is frost-free conditions; it is best treated as a container or indoor plant in temperate climates.
How often should I water Pinklady?
Pinklady originates in moist tropical habitats and prefers consistently moist soil. It tolerates temporarily drier conditions once established but grows most vigorously with regular watering. Avoid waterlogging. In pots, allow the top of the soil to approach dryness between waterings but do not let it dry out completely.
What soil does Pinklady prefer?
Prefers moist, well-drained soils. In its native African range it grows across a variety of tropical soils. No specific soil pH requirement is documented, but slightly acidic to neutral soils typical of tropical environments are likely optimal.
How much light does Pinklady need?
Pinklady grows in tropical environments with high light availability but also persists in partial shade as a forest-floor ground cover. For container growing, bright indirect to direct outdoor sun produces the best flowering and most compact growth.
What temperature does Pinklady prefer?
As a tropical African species, pinklady requires warm temperatures and is frost-tender. It is suited to outdoor growing in tropical and subtropical climates and can be grown as a houseplant or conservatory specimen in temperate regions. It naturalizes in Hawaii and similar climates, indicating tolerance of temperatures from roughly 15 °C upward.
How do I propagate Pinklady?
The plant roots readily at stem nodes when stems contact moist soil, making stem cuttings and layering the most straightforward propagation methods. Rooted stem sections can be potted up individually.
Is Pinklady toxic to humans/pets?
