It grows to between 1 and 2 metres in height, with prickly stems and yellow flowers with a maroon basal spot during spring summer.

Some sources consider it native only to Africa, and naturalised elsewhere;[5] but it is considered a native in New Zealand[3] and Australia[1] It is found in low, swampy areas; in Africa it may occur inland or near the coast, but in all other continents it occurs only in coastal areas.

This distribution, together with genomic evidence, suggests that it originated in Africa, and colonised the other continents through long-range salt-water dispersal.
