• To overwinter well, crocuses need a dry summer. Keep this in mind when overplanting with summer flowers that may need constant watering.
• Propagate crocuses by dividing in autumn. For fall-bloomers, wait until the foliage dies down.
• Fall-blooming crocuses are often confused with Colchicum. Although the flowers are similar, they are actually two different species.
• Good companions:
  • With spring-bloomers plant mini daffodils and species tulips
  • Plant 'Autumn Joy' sedum with fall-bloomers.
• Crocus are most impressive when planted en mass.
