context_page_description: Zantedeschia is a genus of eight species of herbaceous, perennial, flowering plants in the family Araceae, native to southern Africa from South Africa north to Malawi. The genus has been introduced on all continents except Antarctica. Common names include arum lily for Z. aethiopica and calla and calla lily for Z. elliottiana and Z. rehmannii, although members of the genus are neither true lilies of Liliaceae, true Arums, nor true Callas. The colourful flowers and leaves of both species and cultivars are greatly valued and commonly grown as ornamental plants.
context_section_description: The more tender specimens are mainly cultivars (hybrids) of Zantedeschia elliotiana and Zantedeschia rehmannii (referred to as elliotiana or rehmannii cultivars or hybrids, or as e.g. Z. x rehmanii), but also Zantedeschia albomaculata and Zantedeschia jucunda.. These less hardy forms can only survive winter temperatures to -12 °C (Zones 8). This plant must be grown as tender bulbs or houseplants in cooler areas. Species and hybrids between Z. elliotiana, Z. jucunda, Z. pentlandii and Z. rehmannii appear to have an optimum temperature for growth near 25 °C, with growth being suppressed once daily average temperatures persist at 28 °C.
  Z. rehmannii hybrids include 'Amethyst'., 'Crystal Blush'. and 'Neon Amour', while an example of a Z. elliotiana x Z. rehmannii hybrid would be 'Blaze'. Z. elliotiana x Z. maculata hybrids include 'Lemon Drop'. Z. elliotiana hybrids include 'Solar Flare'.
