Petunia is an excellent annual flower to start from seedPetunia
Petunia × hybrida

Starting petunias from seed opens the door to a wide world of beautiful, tubular flowers in shades ranging from striking magenta to subdued lavender to pure white.

To start seeds indoors: Sprinkle seeds onto the surface of the premoistened medium, 10 to 12 weeks before the last expected frost. Don’t cover the seeds—they need light to germinate. Set the flat beneath lights and keep the soil temperature at 70° to 80°F. When seedlings appear (about 10 days), lower the temperature to about 60°F. Transplant seedlings outdoors around the last frost date.
