In spring and early summer the Scadoxus puniceus bears large dense heads (inflorescences) up to 15cm across consisting of numerous smaller scarlet flowers with bright yellow anthers. The flower stalk may reach up to 50-60cm and is often spotted with purple near the base. The inflorescences are borne within bracts which may be large and dark purplish red in colour. Sunbirds, weavers and other nectivorous birds feed on the nectar produced by the flowers.
The large underground bulbs may be up to 10cm across and have a short thick stem at the base from which numerous fleshy roots arise. The plants are dormant in winter and use the large bulbs and roots to store moisture during this period.

However this species is widely used in traditional medicine to treat coughs and gastro-intestinal problems. It has also traditionally been used as part of a medicine taken regularly during pregnancy to ensure a safe delivery
