Description

This low-growing perennial grows 1' tall and 3' tall; it has woody stems with bright green leaves. It produces large, lemon yellow flowers that are up to 4" across and bloom spring through summer and possibly through fall, depending on weather conditions.

Maintenance Tips

Calylophus hartwegii is a soft-textured, low-growing perennial with bright yellow flowers. It only grows 12" tall and up to 3' wide. It is very fast growing in the late winter and early spring, and then it is covered with flowers from mid-spring until fall if the weather is ideal. In the fall, when the days start to get shorter and the rains begin, this plant can decline. The root system will stay intact, but the flowering stops, and the foliage will completely die back. This plant benefits from hard pruning, taking the foliage, and branching almost down to the ground. Don't expect any new growth to emerge until the days start to get longer and warm up. The foliage will start to emerge, and the plant's quick growth and blooming cycle will return.
