Clarkia pulchella is an easy to grow hardy annual, that grows to around 400-500mm (15"- 18") high.
Its ease of growing makes it a useful subject for introducing children to flower growing.
The many flowers in shades of pink through to purple appear from late June to October.
Sow seeds in trays of seed compost and germinate at a temperature 10°-12°C (50°-54°F)
Germination should take four or five days.
Prick out seedlings into cell trays or boxes of potting compost 50mm (2") apart, then place in a cold frame to harden off.
Plant out 300mm (12") apart in full sun and reasonably fertile, well-drained soil.
Planting in groups rather than in rows tends to give a more pleasing display.
Avoid excessive feeding as this encourages leaf growth at the expense of flowers.
