Annual Flowers

38 plants

Annuals live fast and bloom long. While perennials take a year or two to settle in, annuals hit the ground running and don't stop until frost. They fill gaps between perennials, pack a container, or let you try a color scheme before committing. Cosmos are almost impossible to kill. Zinnias are the best cut flower for beginners. Marigolds do double duty as pest deterrents.
