Sida rhombifolia aka Cuban Jute

Sida rhombifolia is in the mallow family, named Malvaceae. People call it broom jute, Queensland hemp, and Paddy's lucerne. Its native range covers the tropical and subtropical Old World. It now grows across much of the tropics. Kew links it to climates with a dry season. It is not native to Britain or Ireland.

This plant lives for years as a small shrub or subshrub. A strong, woody rootstock forms its base and supports branched stems. The stems may stand up or lie on the ground. Parts can be soft, but they often turn woody. Stems reach about 3.3 feet [1 metre] in length. The listed plant height reaches 4.9 feet [1.5 metres]. The source shows blooms and seed capsules as they form. The seeds have awns, which help them catch on passing animals.

In southern China, wild plants grow in scrub and on open slopes. They also grow by streams in that region. In Nepal, they grow on unused land and in open Sal forest. Records there reach about 4,920 feet [1,500 metres] above sea level. The plant can grow in both rich and degraded soils. This wide soil range helps explain why it grows on disturbed land. The sources give no firm light needs for gardens. They give no firm frost limits either.

Its spread is a concern where it has become invasive. Seeds cling to clothes and farm animals, which carry them elsewhere. Mud on vehicles can move seeds from place to place. Seeds can also travel as unwanted bits in hay and crop seed. Several parts of the tropics class this plant as invasive. Its weed risk thus matters when judging its garden value. The evidence shows uses for harvested plants, but no clear role for garden display.

People gather wild plants for food, fibre, and folk remedies. They cook the leaves as greens or make tea with them. The source reports no known hazards. This does not mean the plant is safe for pets. Folk remedies use it for fever, gut complaints, wounds, and headaches. These records show folk use, not proof that the treatments work. Bark yields strong, fine fibre for rope and twine. People tie stems in bundles to make brooms. Some skin-care products sold in shops also use whole-plant extracts. These serve as skin-conditioning ingredients.
