by the Fine Gardening editors

Starting your own plants from seeds is a labor of love. While you end up with a multitude of plants that cost a fraction of those you buy in the nursery, you often have to wait two to three years to see the results of your efforts in the form of bountiful blooms. Not the case with these five perennials. They'll bloom the first year from seed. That's almost-instant gratification.

In early summer, stems emerging from strappy foliage produce vivid orange, 2-inch flowers speckled with red. Seedheads split open in fall to reveal shiny black seeds.
Garden use: Great vertical accent for softer, mounded shapes. A good companion for blue flowers, or for hot-colored gardens of yellows, reds, and oranges.
Culture: Thrives in full sun and well-drained soil. Mulch in cold winter areas. Zones 5-10.
Seed-starting tips: Start indoors 10-12 weeks before last spring frost for earliest blooms. Seeds may take 3 weeks to sprout, but then grow quickly.
