Chinese Forget-me-not

Cynoglossum amabile

The Story

Plant Bio

Cynoglossum amabile, Chinese forget-me-not, is a rounded annual from Nepal and central China, one to two feet high. Softly hairy stalked basal leaves up to eight inches long form a rosette beneath smaller stem leaves, and loose sprays of small funnel-shaped flowers in intense blue open from late spring into autumn.

The blue is deeper and truer than the true forget-me-not it is named after, and it flowers for far longer — from late spring right through to frost rather than a brief spring flush. The seeds carry hooked burrs that grip clothing and animal fur, which is how it spreads, so cut spent stems if you would rather it did not.

Uses & Benefits:

Ornamental UsesSprays of intensely blue flowers over a long season, deeper in colour than true forget-me-nots.
Practical UsesTolerates poor dry soil, flowers for months, and cuts well for small arrangements.
Ecological BenefitsPollinators work the flowers steadily from late spring through to frost.

Planting

How to Grow

  1. Sow direct in spring where plants are to grow.
  2. Choose full sun or partial shade and drained soil.
  3. Thin seedlings rather than transplanting them.
  4. Water sparingly; it tolerates dry soil well.
  5. Deadhead to prolong flowering and limit seeding.
  6. Expect burred seed to catch on clothing.

Pro Tip

The seed is burred and catches on clothing and fur, so deadhead before it ripens unless you want it everywhere next year.
