Bulbil Watsonia
Watsonia meriana var. bulbillifera

Watsonia is native to South Africa and has been cultivated in Australia for more than 150 years. It has become a serious weed in moist regions where it colonises creek banks, remnant forest and roadsides. It is a sunloving herbaceous perennial to 2 m which holds its orange flowers on a tall spike above the foliage. It was introduced as an ornamental and was popular because of its hardiness and bright flowers.



  • Watsonia meriana var. bulbillifera does not produce seed but spreads by cormels (bulbs) that develop along the flowering stem. These cormels are spread by water.
