  • Genus Massonia are bulbous perennials with two oblong to elliptic leaves and dense heads of white or pink flowers of which the large stamens are the prominent part, usually opening in winter

  • Details M. depressa is a winter-active bulb producing just two leaves up to 25cm long, which lie flat on the ground. A cluster of small, off-white flowers appear in the centre. These have a yeasty smell that attracts gerbils to pollinate plants in the wild. The green fruits follow as an interlocking cluster of three-lobed capsules
