East from seed, sow thinly where they are to flower
Aim to sow 0.12 inches (0.3 cm) deep and try to ensure a gap of at least 5.85 inches (15.0 cm). Soil temperature should be kept higher than 15°C / 59°F to ensure good germination.Sow thinly and thin the seedlings if necessary, to give the plants enough too to grow
Ensure that temperatures are mild (minimum night temperatures should be around 10°C / 50°F) and all chance of frost has passed before planting out, as Double Red is a half hardy plant.Seed heads can be used in arrangements and for decoration. Collect when fully dry on the plant
This variety tends to be ready for harvesting by late summer.
