Estimated Native Range
Summary
Hibiscus calyphyllus, commonly known as Lemonyellow Rosemallow, is a deciduous shrub native to open savannahs and the edges of forests in tropical and southern Africa. It typically grows to 1-1.8 meters (3–6 feet) tall and wide, with a loose, open form. The plant is adorned with large, showy flowers measuring 8–10 cm (3–4 in) across, featuring a bright yellow color and a contrasting brownish center. These blooms are particularly notable for their day-blooming habit, opening several hours after sunrise and closing before sunset. Hibiscus calyphyllus stands out from many African Hibiscus species as a summer bloomer, allowing it to be cultivated successfully in North America and Europe where it can produce viable seeds. These seeds are easy to collect and germinate, and with an early start indoors around February or March, the plant can flower in its first year.
Lemonyellow Rosemallow is valued for its vibrant summer flowers and the ease with which it can be propagated from seeds. It is often used in tropical and subtropical gardens for its ornamental qualities and can serve as an accent plant or part of a mixed border. It requires full sun to part shade, consistent moisture, and well-drained soil to thrive. While it is not commonly known for any particular diseases, it can be susceptible to pests such as aphids and spider mites. Gardeners should also be aware that it may require protection from frost in cooler climates.CC BY-SA 4.0
