About Arrowleaf sida
Sida rhombifolia, commonly known as ballast-hamp, is a perennial subshrub belonging to the Malvaceae family, prized for its small, hibiscus-like yellow flowers that bloom for much of the year. Its upright and branched habit makes it suitable for garden borders, rockeries, or as a groundcover in warm climates. Despite being considered a 'weed' in some regions, its hardiness and continuous flowering make it an interesting choice for low-maintenance gardens.
Native range
Tropical and subtropical regions of the Americas, including the southern United States, Mexico, Central America, the Caribbean, and South America.
Care tips
It prefers full sun to partial shade and tolerates a wide range of soils, though it thrives best in well-drained substrates. Watering should be moderate, allowing the soil to dry out slightly between waterings, as it is quite drought-tolerant once established. A common mistake is overwatering, which can lead to root rot, especially in heavy soils. It does not require regular fertilization but benefits from light feeding in spring.
