Onion Grass or Guildford Grass (Romulea Rosea)

Onion Grass is a perennial grassy weed with between three and 10 thin, strappy leaves rising from the central base up to 30 cm long. The leaves are up to 2 mm wide with a prominent central midrib that protrudes to create an almost cylindrical leaf blade in cross section in a spear and quite a tough point.

Flowering in spring, the onion grass plant produces two to four small flowers per plant that are positioned around the base of the plant. The flowers are purple in colour with a base and centre, comprising of six lanceolate petals about 10 mm in length.
