They are generally open for two days during the flowering period and each inflorescence presents on to four open flowers at once. The flowers are produced in a panicle 15вЂ“25В cm long, each flower 2.5-3.5В cm long, bright red on the outside, and white inside. The flower comprises 5 lanceolate petals, which remain mostly closed together forming a sharpening cylinder. Terminal red-branched racemes of panicles, 10вЂ“30В cm long, produces narrow, vivid crimson flowers, 2.5-3.5В cm long, that decorate the tips of each little limb.
