  • Family Iridaceae

  • Genus Crocus are dwarf, deciduous perennials growing from a corm, with linear leaves usually with a silvery central stripe, and goblet-shaped, sometimes fragrant flowers in autumn or early spring

  • Details 'Vanguard' is usually the earliest of the large crocus cultivars to flower, in February. Sometimes described as a ""bicolour"", the outer petals have greyish backs, contrasting with the mauve inner parts. Closed buds look silvery grey; open flowers all lilac with orange styles. The early flowering and large size make it a valuable plant for early bumble bees
