Family

Boraginaceae

Botanical Name

CYNOGLOSSUM amabile

Plant Common Name

Chinese Forget-Me-Not, Summer Forget-Me-Not

General Description

Prized for its summer-long display of azure flowers, this short-lived tender perennial from East Asia is typically grown as an annual or biennial.

Dense clumps of felted, gray-green, lance-shaped to oval leaves give rise to one-sided sprays of small, five-lobed, sky-blue flowers on calf- to knee-high stems. Flowering begins in early spring or 2 months after sowing, continuing as long as temperatures remain mild. Small, bristly, bur-like fruits follow the flowers. Self-sowing often occurs, sometimes resulting in successive waves of bloom.

An excellent subject for mixed borders and cottage gardens, Chinese forget-me-not prospers in full to partial sun and moderately fertile, well-drained soil. Sow it in spring for summer-long bloom in areas with harsh winters and mild summers. In mild-winter regions sow it in fall for spring display. Garden centers sometimes offer plants. Pink- and white-flowered forms are occasionally available.
