Crocus

There are spring flowering and autumn flowering crocus.

  • easy to establish, and most will self-seed and spread in grass and wilder areas.
  • plant corms 3-4 inches (8-10 cm) deep.
  • plant spring flowering crocus in autumn and autumn-flowering types late summer.
  • choose areas that are full sun in gritty well-drained soil.
  • crocus thrive in gravel and do well interplanted with saxifrage, dwarf dianthus and other alpines.
  • with careful selections you can enjoy crocus from late winter to late spring, then again from early to late autumn.
