You know that old saying that “friends don’t let friends grow annuals”? I now ignore that sentiment. Some of the best plants in my garden are annuals, and they are more than worth the effort of growing them every year. Annuals add bold color to my containers and beds, fill in spaces beautifully, and bloom for longer than any coneflower (Echinacea spp. and cvs., Zones 3–9) or phlox (Phlox spp. and cvs., Zones 3–9), so they bridge the flowering gaps between my perennials’ bloom times. But over the last few years as I’ve strolled the ever-more-homogenized aisles of the garden centers in my area, I’ve found myself bored silly, and in sticker shock. I always buy a few standard sweet potato vines (Ipomoeabatatas cvs., annual), calibrachoas (Calibrachoa cvs., annual), and coleus (Plectranthus scutellarioides cvs., Zones 10–11), of course, but if I want something a little different, I grow it from seed.
