Attractive mango yellow Calla Lillies 'Zantedeschia' are exotic, with trumpet-like flowers which come back every year from the tubers and will form a clump, this can then be divided and re-planted. Making them very easy to grow and a perfect addition to any garden. Remember to space out your Calla Lilies equally allowing them to reach their maximum height and width. Simply dig a hole, place them in it, cover with soil, pat down firmly and then water. You can buy 3, 5 or 10 corms.
