Perennial seeds require a wintering period for germination. For autumn sowing, sow in pots, making sure to cover the seeds very lightly, or sow directly in the ground, taking care to protect them with mulch, for example. For spring sowing, place the seeds in a damp substrate in the fridge for a month. Transplant when germination begins.
