The autumn crocus, or naked ladies, as the flowers appear in autumn, without leaves. These arrive in spring, erupting through ground cover of Vinca or Geranium macrorrhizum, which protect the flowers from mud splash in autumn. In the wild they grow in meadows, rocky hillsides and in open woods. Full sun is their best situation, but some light shade will also work. They are similar to Crocus, but Colchicum have six stamens, (Crocus 3) and flowers tend to be larger.
