Hardy fall bulbs such as Daffodil, Tulip, Hyacinth, Crocus and Snowdrop are spring flowering plants that must be planted in the fall. They are mostly native to mountainous areas of Europe and the near east ñ Spain, Turkey and Afganistan. They actually need the dormant rest period of a long, cold winter. The melting snow and ice in early spring provide needed moisture as they start to grow and flower. Plant from September to December, even after the first frost if the ground can still be worked.
