There are countless ways to enjoy this cheery, sun-loving vine: window boxes, ground cover, on a trellis as a screen, in hanging baskets, decorating mailboxes, and columns. Very fast growing with lush foliage and masses of blooms all summer long in a dazzling, eye-catching array of sunset hues; the petals make a brilliant contrast to the dark, 'Spanish eyes'.
