Easily grown in average, medium, well-drained soils in full sun to part shade. Plant corms about 2-3” deep and 3-4” apart in the fall. If planted in the lawn, foliage should be left unmowed until it yellows (about 6 weeks after bloom). Naturalizes well. Plants go dormant by late spring.
Crocuses are among the most widely grown early spring bulbs (actually corms). Native to Greece and Asia Minor, Crocus chrysanthus is commonly called snow crocus because it is one of the earliest crocuses to bloom. It typically blooms in late winter to early spring around the time of snowdrops (Galanthus) but usually before the popular Dutch hybrid crocuses. Species flowers are yellowish orange. ‘Advance’ features upright, cup-like flowers that are lemon yellow with purple shading on the outside. Typically grows 4-6” tall. Basal, grass-like leaves. Flowers close at night and open up in the morning, but usually remain closed on rainy/cloudy days. Sometimes also commonly called golden crocus.
No serious insect or disease problems. Squirrels, mice and other rodents can be problems. Squirrels seem particularly adept at locating, digging up and eating newly planted corms.
Brings early spring bloom to the landscape. Mass in lawns, under trees or in sunny woodland areas. Large sweeping drifts can be spectacular. Also may be grouped in rock gardens, in front of shrubs, along walks or in various other small areas around the home.
