How to grow

Sow seeds after the last frost on well-drained soil and press in lightly, since they need light to germinate. Keep evenly moist until seedlings appear, then water when the top inch of soil dries. Plant in full sun to partial shade for the heaviest bloom. Shear the plants back lightly after the first flush to encourage fresh, continuous flowering through the season.
