Lily of the Valley: Sowing, planting and harvest calendar
How do you sow lily of the valley outdoors?
Growing lily of the valley from seed is slow and takes patience. To increase an established clump more easily, you can divide its rhizomes in autumn instead. If you choose to sow, use ripe seeds with the berry flesh removed, or seeds bought from a reliable supplier. The berries are poisonous: do not eat them.
Sow the seeds in a pot of free-draining seed compost, following the supplier's instructions for sowing depth. Keep the pot outdoors in a cold frame, sheltered from scorching sun, and keep the compost slightly moist without waterlogging it. Germination can take a long time: keep the pot and check it over the seasons. Let the seedlings develop before planting them in shade or partial shade.
