Annuals. Brilliant reds, bright oranges and shining yellow blossoms sparkle among the dazzling blue and purple flowers in a vibrant display lasting through the spring, summer and fall. Easy to grow, 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. As your flower bulbs finish blooming, these annual flowers continue the show and fill the area with nonstop color. Best for areas with at least 6 hours of direct sun. All plants in this mix are annuals but many will self-seed and come back the following year.
