Planting and Growing Nemophila

Easy to grow from seed. Grow in moist but well drained soil, in sun or partial shade. Dislikes very hot, dry conditions.

Ideal for the edge of the border or in a cool moist spot in the rockery. Also useful in pots and containers.

Not suitable as cut flowers as the blooms fade quickly when picked.

Taking Care of Nemophila

Keep the soil moist and weed free but not waterlogged.


Trim back after flowering to encourage a second flush. Pull up and discard plants to the compost heap, once the flowering season has finished.

Pests and Diseases

Can be affected by Aphids.

Propagating Nemophila

Should be sown where it is to flower as it dislikes root disturbance.

Prepare the ground well and dig in plenty of organic matter before sowing. Sow seeds from March to May, covering lightly with fine soil. Gradually thin to 6in (15cm). Make 2 or 3 three sowings for successive flowering.

Alternatively, sow in September for an early show the next year, and protect with cloches over-winter.
