Germination can take from 1 -3 months at 15-21C, to speed this up seal in a polythene bag after sowing and leave in a refrigerator. Inspect regularly and remove if any start to germinate in the fridge. Transplant when large enough to handle into 7.5cm pots. Move to a cold frame or plunge the pots up to their rims in a sheltered site outdoors and plant out in autumn, 12in apart in moist well drained soil, sun or part shade.
