If you're looking to add some sophistication with a dash of merriment to your garden, consider this mix assembled by our flower experts in Holland. This well balanced blend of pink and purple calla lilies looks fabulous planted together, and all share the same flowering period of mid to late summer. The blooms, which display the classic upright trumpet shape, are delightful in borders, containers or arrangements. Carefree and exotic looking, callas perform best when grown in full sun and well-drained soil.
