Species or Botanical Crocus

Species Crocus, commonly known as Snow Crocus, date back to before the 18th century, native to Europe, North Africa and western Asia. They are the earliest Crocus to flower, sometimes at the same time as Galanthus; if not, soon thereafter. Blooming about two weeks before their Large Flowering siblings, Species Crocus are best for early spring lawn tapestries: hold off mowing the lawn until the foliage has died back. Drifts are also lovely in garden borders and rock gardens. They have graceful six-petaled, 4" tall flowers that open and close on sunny days, and grass-like foliage (the foliage of some varieties has narrow, median silvery stripes). Deer-resistant, they naturalize readily in well-draining soil and in full to partial sunlight. They may be a target for squirrels that may dig up newly planted bulbs for a snack, or for transplant elsewhere. They naturalize by corm offsets (baby corms on the sides of the originally planted corm) and sometimes, when mature and happy over time, by self-sowing seed. Species Crocus have either smooth (annulate) or fibrous (reticulate or netted) tunics depending on the variety. You’ll need about nine corms (bulbs) per square foot for a dense planting. (Square footage is determined multiplying the planting site’s length times its width.) Bulb size: 5 cm/up. Full to partial sunlight. Bloom time in horticultural zone 5: Late March/early April. Plant 4" deep and 3" to 4" apart. HZ: 4-8. Height: 4". (Crocus are also good for forcing indoors over the winter. Pot them up in mid-October and precool them at a consistent, dark 38 to 45 degrees F for eight to ten weeks with moderate watering. Bring them into the house~they will bloom about four weeks later.)

Crocus are The Art & Soul of Spring.
