Guide to Starting Annual Flower Seeds

Save money and grow flowers not usually available in stores by starting your own annual flowers.



Most annual flower seeds are easy to start indoors. And by starting your own bedding plants, you’ll not only save money, but you’ll also be able to grow hundreds of cultivars and unusual species not available at the garden center.

Ageratum houstonianum

Butterflies love ageratum’s fuzzy blue, pink, or white blooms. Grow these mounding plants in beds or containers and be sure to cut some stems for indoor arrangements, too.

To start seeds indoors: Start the seeds 6 to 8 weeks before the last frost date. Scatter the seeds on the surface of the soil—don’t cover them because they need light to germinate. Keep the soil temperature at 70° to 80°F; sprouts should appear in 5 to 10 days. Transplant the seedlings outdoors after all danger of frost has passed.
