F. x ananassa Pretty enough for placement in flowerbeds, containers, and hanging baskets. Rainbow Treasure is a flowering groundcover with multi-hued, white, pink, and deep rose blooms. Its creeping habit lends itself extremely well to fill in around perennial plantings as well as covering spaces between berry bushes and other fruiting plants. We recommend planting these beautiful plants close at hand for easy enjoyment of the large, sweet, fragrant berries.
