  • Information
  • Dutch Large Flowering Crocus
    Blooming about two weeks after Species Crocus, Large Flowering Crocus date back to the 18th century, and are sometimes called Giant Dutch Crocus or referred to as the Wild Crocus of the Alps or the Pyrenees. Drifts en masse are spectacular in garden and pathside borders as well as in meandering rivers through sun dappled woodlands. They may also be blended with early spring flowering Kaufmanniana and select Species Tulips and/or early flowering Narcissi (like Jetfire and Tête à Tête) for signature displays. They have graceful six-petaled, 5" tall flowers that open and close on sunny days, and grass-like foliage with narrow, median silvery stripes. Deer-resistant, they naturalize readily in well-draining soil and in full to partial sunlight. 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. These corms have fibrous (reticulate) tunics. 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.) They may be a target for squirrels that may dig up newly planted bulbs for a snack, or for transplant elsewhere. Bulb size: 9 cm/up. Full to partial sunlight. Bloom time in horticultural zone 5: April. Plant 5" deep and 4" apart. HZ: 4-8. Height: 5". (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.)
