boaterbush
Waltheria indica L.

Waltheria indica is a pantropical flowering plant in the mallow family, Malvaceae, and is thought to have originated in the Neotropics. Commonly known as boaterbush, it is a short-lived subshrub or shrub that typically grows up to 2 meters tall with a stem diameter of 2 centimeters. It is often found in disturbed or well-drained, moist environments and is adapted to a range of habitats, including dry and wet conditions. The plant is widely distributed across tropical regions and has a number of local common names, such as sleepy morning, hierba de soldado, and ʻuhaloa in Hawaii.
Description
Waltheria indica is a subshrub that thrives in open forest, thicket, forest galleries, riverbanks, and wooded savannahs. It is also commonly found in fallow and disturbed sites. The plant is characterized by its woody base and herbaceous upper parts. Its leaves are typically simple and alternate, and the flowers are small, with five petals and a central column of stamens typical of the Malvaceae family. The fruit is a capsule containing numerous small seeds. In Angola, it is known as njinji (ub) and is used for medicinal purposes.
Habitat
Waltheria indica is highly adaptable and can be found in a variety of habitats, including open forests, thickets, forest galleries, riverbanks, and wooded savannahs. It is also common in disturbed and fallow areas. The plant prefers well-drained soils and can tolerate both dry and moist conditions. In Puerto Rico, it grows in regions receiving 750–1,800 mm of annual rainfall and at elevations from sea level to over 400 meters. It is often associated with transitional zones between forests and open areas.
Cultivation
Waltheria indica is not commonly cultivated but can be grown in tropical and subtropical gardens where it thrives in well-drained soils and partial to full sun. It is relatively easy to propagate from seeds or cuttings and benefits from occasional pruning to maintain a compact shape. Due to its adaptability, it can tolerate a range of soil types and is drought-tolerant once established. However, it is best suited for warm climates and may struggle in cooler or more humid regions.
Uses
Waltheria indica has traditional medicinal uses in several regions where it is found. In Angola, it is used for its therapeutic properties, though specific applications are not detailed in the literature. The plant is also valued for its ecological role in stabilizing soil and providing cover for small animals in disturbed habitats. In some areas, it is used ornamentally in gardens due to its attractive foliage and flowering habit. Additionally, it may serve as a pioneer species in ecological restoration projects due to its ability to colonize disturbed sites.
