Can be found on roadsides, waste places, fallow fields, plantations, secondary growth, teak forests, often naturalized as a noxious weed. It is found at elevations from sea level up to 2,000 m. Prefers humus-rich, medium-textured soils but can succeed in a range of conditions as long as the soil is well-drained.

• Stems - covered with star-shaped (stellate) hairs; often many branched at the base.
• Leaves - simple, alternate, with the upper surface rough and the lower surface grayish, broadly ovate, often with 3-5 shallow, angular lobes at apex, up to 10 cm long; margins finely toothed, bases heart shaped, petioles up to 5 cm long; stipules tiny.
• Flowers - small, showy, hibiscus-like, solitary on short stalks in leaf axils, subtended by 5 basally united (involucral) bracts up to 0.7 cm, calyx 5-lobed, hairy.
• Fruits - subglobular schizocarp, composed of 5 trigonous, indehiscent, 1-seeded mericarps, 4-5 mm long, covered with barbed bristles and athick cover of stellate hairs.

Propagated generatively by seeds. Germination rates and time are much improved if the seed is scarified prior to sowing. It is usually sown at the beginning of the rainy season up to 2 cm deep in a well-prepared seedbed. Plants are closely spaced to prevent branching. Sowing may be done in rows (1-2 cm deep) or the seed may be broadcast.
