Seed Saving

If left alone this insect-pollinated plant will eventually produce seed and may even self-sow. There aren't many varieties, so you probably don't have to worry too much about cross-pollination.

Gather the seed heads as the seeds start to turn brown and leave them to dry in a paper bag in a warm place.

Seed Viability in Years: 2 - 4 Years

Germination Percentage: 70%
