Self blanching variety
Sow in a propagator on a windowsill or in a greenhouse at 10-15C using a quality moist compost. Just cover the seeds (appox 3mm) with sieved compost. Transplant seedlings singly into 50mm pots and grow on. Plant out when all risk of frost has passed in a block formation to help blanching.
