Last year I planted some gaillardias from seed. They didn't do much besides survive. This year they took off and they are such bright colored beauties. Such cheerful little mounding plants. They love well drained, sunny spots and are great drought survivors. I really recommend that you just get plants rather than trying to grow them from seed.
This is a close-up of one of the blooms. These plants slowly spread and are fairly reliable to return each year for at least several years. They don't get very tall and have a pretty long bloom time.
