Also known as C. flavus Yellow Mammoth, this 17th century heirloom has six-petaled, rich buttercup-yellow flowers with matching anthers and grass-like foliage with narrow, median silver-white stripes. Dutch Large Flowering Crocus, sometimes called Giant Dutch Crocus or the Wild Crocus of the Alps or the Pyrenees, bloom about two weeks after Species Crocus. Drifts en masse are spectacular in garden and pathside borders, and in meandering rivers through sun dappled woodlands. (If you do plant them in lawns, mowing should be held off until the foliage dies back naturally, about five weeks after blooming.) Golden Yellow has graceful six-petaled, 5" tall flowers that open and close on sunny days, and grass-like foliage with narrow, median silver-white stripes. Deer-resistant, they naturalize readily in well-draining soil and in full to partial sunlight. These larger corms have reticulated tunics. They may be a target for squirrels that may dig up newly planted bulbs for a snack, or for transplant elsewhere. You’ll need about nine corms (bulbs) per square foot for a dense planting.

Crocus Class: Dutch Large Flowering. 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°F to 45°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.
