Its unique flowers are the main interest of this scrambling shrub: each is a narrow, yellow tube backed by a broad, circular calyx, appearing in dense terminal clusters through summer and fall (autumn). The mid-green leaves are oval and slightly serrated. Its long, trailing canes make it ideal for espaliering. Rampant growth can be contained by pruning after flowering and old canes can be removed. There are also red- and bronze-flowered forms. Full sun but will bloom in filtered light. Sometimes this species is called Holmskioldia sanguinea Mandarin.
