Products > Zantedeschia aethiopica 'White Giant'   Zantedeschia aethiopica 'White Giant' - White Giant Calla     [2nd Image] Habit and Cultural Information Category: Bulb/Tuber/Rhizome etc. Family: Araceae (Arums) Origin: South Africa (Africa) Variegated Foliage: Yes Flower Color: White Bloomtime: Spring Height: 4-8 feet Width: 3-4 feet Exposure: Cool Sun/Light Shade Irrigation (H2O Info): Low Water Needs Winter Hardiness: 15-20° F May be Poisonous  (More Info): Yes 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  The information on this page is based on research conducted about this plant in our library and from reliable online sources. We also take into consideration observations of this plant in our nursery crops, as well as of plants growing in the nursery's garden and those in other gardens we visit. We also will incorporate comments that we receive from others and welcome getting feedback from anyone who may have additional information, particularly if it includes cultural information that would aid others in growing Zantedeschia aethiopica 'White Giant'.     [MORE INFO]
