Latin: Dianthus plumarius
Season & Zone
Exposure: Full sun to partial shade
Start Dianthus seeds indoors 8 to 10 weeks before transplanting out, or direct sow them in early spring or early autumn so that the seeds may be exposed to frost. Ideal temperature: 15-21°C (60-70°F). Seeds germinate in about 10 days.
Just cover the small seeds very lightly with soil. Aim to space plants 15-23cm (6-9″) apart.
Grow in rich, well drained soil with a pH range of 6.0-7.5. Water established plants only during dry spells. Cut back the short stems after flowering, and be sure to mulch if very cold weather is expected. Replenish with new seeds every 3-4 years.
