For success with these plants, get them started indoors in late January or early February.  Click here for seed starting ideas.  This is also how you can grow them, as annuals, in colder regions. Transplant into the garden after all danger of frost has passed. This will ensure that your plants will be well developed before the cold weather sets in.

Grown from seed, up to 25% of the plants will be useless.  This is due to the genetic makeup of the plants and not an inherent problem with our seed stock.  Cull sickly and albino plants at transplanting time.  Eliminate non-productive plants after the growing season is over.

From your select plants, you will be able to save seed and divide the clumps to increase your stands.  Division is a good method for propagating additional plants with known traits.
