Sunset Bells prefer a semi-sunshine environment, and can grow well in a scattered light environment. The leaves are prone to yellowing and injury when exposed to the hot sun. Indoor cultivation is prone to barren growth when the light is dim, and the old leaves fall off and do not blossom. Watering can observe the leaves slightly weakly before sufficient watering, the leaves should be wet to avoid disease invasion. Apply long-acting fertilizer once a season from spring to fall. If there are thick branches it can be cut off. In winter, the ground is dry and overwintered with bulbous roots, which can reduce the number of watering to avoid frostbite. The propagation was carried out by cuttings. The cuttings were cut in summer with 1 to 2 sections of full branches, and the leaves could be cut half to avoid excessive evapotranspiration of water.

In warm areas, Sunset Bells can be planted directly in the shade of the courtyard trees and used as ground cover.
