About

This shrub is distinctive for its unique spathe-like calyces, which enclose delicate, tubular white flowers. Following flowering, it develops small, spherical berries, adding subtle interest to the garden.

Where it works in Kilifi

This adaptable shrub thrives in partial shade but can tolerate full sun in coastal Kilifi conditions, preferring well-drained soil. It makes an excellent specimen plant or addition to a mixed border, and can also be used for understory planting, requiring space for its eventual spread.

Growing notes

It exhibits a moderate growth rate, establishing itself well once planted. While it appreciates regular watering during dry spells, established plants show good drought tolerance and are ideally suited for the warm, humid Kilifi climate.
