About this weed

Originally from southern Africa, Romulea flava was probably introduced as an garden plant. It is now occasionally cultivated as an ornamental but has not become naturalised.

Description

Romuleas flava is a cormous, perennial growing to 0.45 m high. It bears yellow flowers in winter and early spring. The fruiting stalk extends following flowering. The corm is annually renewed and reproduction is usually by seed. The seed is then dispersed by water and machinery. The time to first flowering is 2 years and the seedbank persists for up to 5 years. It generally survives fire.
