CROCUS 'Blue Pearl'
Hybrid Crocus, Spring Crocus
A welcome sight in late winter, this heirloom crocus opens its cheerful flowers while the last remnants of snow still linger. Introduced in the mid-twentieth century, it is one of many hybrids that trace their ancestry to Crocus chrysanthus and C. biflorus.
Growing from a small bulb-like storage organ known as a corm, this diminutive herbaceous perennial sends up one to four pale blue flowers in winter or early spring, just as the grassy, shiny, dark green leaves emerge. Held singly atop ankle-high, stalk-like floral tubes, the up-facing, goblet-shaped blooms have six "petals" (or segments) in two whorls. The three outer segments have a blue central blotch and a copper-yellow basal blotch on their exteriors. In bright sun the flowers open wide to reveal yellow anthers, orange stigmas, and a yellow eye. The floral tube is deep purplish-blue. The foliage goes dormant by late spring.
Grow 'Blue Pearl' in friable, well-drained soil in full sun or light shade (when it is in leaf). Plant corms at a depth of two to three times their height in late summer or early fall. Ten or more weeks of near-freezing temperatures are needed to induce flowering. Group this little beauty in rock gardens, mixed borders, alpine troughs, or turfgrass, or force it in pots to help quell winter doldrums.
