CROCUS sieberi ssp. sublimis 'Tricolor'
Sieber's Crocus, Tricolor Sieber's Crocus
Opening its winsome blooms with the first hints of spring, 'Tricolor' is an heirloom cultivar dating from the early twentieth century. It is a selection of Crocus sieberi ssp. sublimis, native to southeastern Europe and Crete.
Growing from a small bulb-like storage organ known as a corm, this diminutive herbaceous perennial sends up one to three lilac-blue flowers in winter or early spring, just as the grass-like green leaves appear. Borne singly on short, erect, stalk-like floral tubes, the six-"petaled" flowers open wide in bright sun to display a luminous gold, white-rimmed throat. The orange-yellow anthers and styles add to the display. Once flowering ends, the foliage remains for several more weeks to gather nourishment for the bulbs.
Grow this delightful crocus in full sun and fertile, well-drained soil. Plant the corms in late summer or early fall at a depth of three or four times their height. Plants need several weeks of winter chill to grow and flower well. This little beauty is perfect for clustering in the rock garden or massing in the foreground of perennial beds. It also is good for forcing in containers.
