It's hard to say much more than "WOW" when you see African Gold Calla Lily. This incredible selection of the South African Zantedeschia aethiopica has green leaves with golden striped veins. In spring, the clump is topped with 2' tall spikes ending in white chalice-like flowers...what a combination. Zantedeschia aethiopica is a winter-growing species, so it is summer dormant in hot climates, re-emerging in early fall, and remaining evergreen all winter in milder climates. In climates with cold winters, plants in the ground usually start flowering in early spring. The intensity of the leaf pattern is best in early spring, fading somewhat in the heat of summer.

Maintenance:

Calla lilies (Zantedeschia) are low maintenance. To keep them at their most attractive state, merely remove leaves and flowers as they fade. When grown in an area with alternating warm and cold spells in the winter, the lush growth produced by Zantedeschia aethiopica during a warm spell can be frozen by a cold spell; merely cut away the damaged foliage and they will soon put up new growth. They do not seem to be harmed by this interruption. The other commonly grown species remain dormant through the winter.

Growing Conditions:

Zantedeschia aethiopica is at its best when grown in a wet site. Indeed it will thrive grown in a pot submerged in water. Its performance in a drier location will be disappointing. Please note that this applies to this one species of calla lily, Zantedeschia aethiopica. The other commonly grown species:the yellow flowered Zantedeschia elliottiana, the white flowered, white speckled leafed Zantedeschia albomaculata and the pink flowered, Zantedeschia rehmannii will thrive in soils of medium moisture level. This also applies to the hybrids between these 3 species. All are winter hardy in zone 7 so the tubers can be left in the ground over winter. All want sun for at least half a day. It is best to remove spent flowers so seeds are not produced. Named cultivars could be swamped by inferior seedlings if the seed was allowed to drop and grow.

Natural Impact:

The flowers of calla lilies are of course very showy and dramatic. They are also superb cut flowers, lasting many weeks. The broad foliage of most species is also an asset, contrasting with finer textured plants. The white speckling of some species, or the gold striping of Zantedeschia aethiopica 'African Gold' is an additional ornamental feature.
