CROCUS vernus 'Grand Maître'
Providing a welcome splash of color at winter's end, this 1924 introduction is one of the oldest of the many widely grown, large-flowered selections of the European native Crocus vernus. Like all other crocuses, it is a diminutive herbaceous perennial that grows from a small bulb-like storage organ known as a corm. In late winter or early spring, one or two lavender-blue flowers with silvery overtones arise on ankle-high, stalk-like floral tubes. The up-facing blooms have six "petals" (or segments) in two whorls. Goblet-shaped when closed, the blossoms open in bright sun to reveal the orange-yellow anthers and stigmas. Tufted, grassy, dark green leaves with white midstripes emerge with the flowers and go dormant by late spring.
Grow this beautiful little "bulb" in friable, well-drained soil and full or partial sun (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 charmer in rock gardens, mixed borders, or turfgrass. Plants often self-sow. This crocus is also good for forcing in pots.
