Botanical Name

CROCUS 'Dorothy'

Plant Common Name

Hybrid Crocus, Spring Crocus

General Description

A welcome sight in late winter, this heirloom crocus opens its cheerful flowers while the last remnants of snow still linger. Originating in the early twentieth century, it is one of many hybrids that trace their ancestry to Crocus chrysanthus and C. biflorus. As with all other crocuses, this diminutive herbaceous perennial grows from a small bulb-like storage organ known as a corm. In late winter or early spring, one to four golden-yellow flowers arise on ankle-high, stalk-like floral tubes. Goblet-shaped when closed, the blossoms have brownish-purple stripes and stippling on the exteriors of their three outer segments. The stippling continues on the floral tube. In bright sun the blooms open wide to reveal the three inner segments and a yellow-green eye. Short, tufted, grassy leaves emerge with the flowers and go dormant by late spring.

Grow 'Dorothy' in friable, well-drained soil in 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 little beauty in rock gardens, mixed borders, alpine troughs, or turfgrass. Plants may self-sow. It is also good for forcing in pots to diminish winter doldrums.
