Sowing & growing

Sow under cover from Sep-March, into seed compost at 18-22°C for 2-4 weeks. Seeds will need to cold stratify for 4-6 weeks before moving back to area of 18°C. Germination may take time. Direct sow Sep-Dec or leave seeds sown in pots outdoors for germination the following spring. Acclimatise plants started under cover before planting out.

Aftercare

Deadhead regularly to encourage more flowers during growing season.
