Bright blossoms sparkle in a vibrant display that lasts through the spring, summer, and fall. Sow seeds wherever you want a dash of color. Once established, plants need only minimal care. Sow in spring where bulbs such as crocus, daffodils, and tulips emerge, so that as your flower bulbs finish blooming, these flowers continue the show and fill the area with nonstop color. Many plants in this mix may reseed and come back the following year.
