Growing From Seed

Growing your own native plants from seed is the most economical way to add natives to your project or home garden. The seeds of native plants have built-in dormancy mechanisms that protect them from germinating before killing frosts or periods of drought.

In cultivation, the successful gardener must become familiar with these conditions to unlock the dormancy mechanism and stimulate germination. We are developing thorough seed germination categories in the Seed Details section above to help you successfully grow the native seed we sell.
