Half hardy Annual
Description – Fluted sea shells around a button like centre. Finely cut, ferny foliage also useful for cutting.
Sowing – Sow 3mm (1/8in) deep in spring at 21-24C (70-75F) in a good seed compost. Keep soil damp but not wet, sealing in a polythene bag after sowing is helpful. Germination usually takes 5-10 days.
Growing – When seedlings are large enough to handle, transplant and grow on in cooler conditions. Gradually acclimatise to outdoor conditions for 1-15 days before planting out after all risk of frost, 6cm (24in) apart in a sunny spot on light well drained soil.<
Flowers – July to October
