Zantedeschia aethiopica 'White Giant' (White Giant Calla) - This is a robust herbaceous perennial that forms a large clump of arrow-shaped white-spotted leaves and flowers that can reach to 7 feet tall. As with other Zantedeschia aethiopica, the showy part of the flower is actually a bract called a spathe that surrounds the spike of fragrant yellow flowers in the center that is called a spadix. Treat as you would the typical Calla but give it more space. This species of calla can be evergreen on the coast if irrigated during summer months but is otherwise summer dormant. In colder climates it can freeze back with a frost but quickly recover. In coastal irrigated gardens flowering is often year-round or in late winter to early summer if not irrigated. Plant in full coastal sun or light shade with seasonally or year round moist soil. This plant is suitable to a dry garden as it persists in gardens without supplemental irrigation but is also useful in well-irrigated gardens or along the edge of a pond. 'White Giant' came to us from Tony Avent of Plant Delights nursery and on his website Tony said that he got it from the bay area garden of Sonny Garcia, where the flowers reached above his head. This is a great Calla Lily but we were relying on a tissue culture lab for propagation and this lab closed in 2013 - we may not have this plant in large numbers for a while. W  Information on this page is based on research conducted in our nursery library, from online sources, as well as from observations made of this plant as it grows in our nursery, in the nursery's garden and in other gardens where we have observed it. We also will incorporate comments received from others and welcome getting feedback of any kind from those who have additional information, particularly if this information is contrary to what we have written or includes additional cultural tips would aid others in growing Zantedeschia aethiopica 'White Giant'.
