Permapeople description
Zantedeschia aethiopica, commonly known as arum lily, is a rhizomatous perennial plant native to southern Africa. It is widely cultivated for its elegant, trumpet-shaped white flowers and is often used in bouquets and floral arrangements.
Botanical description
Zantedeschia aethiopica is a rhizomatous herbaceous perennial plant, evergreen where rainfall and temperatures are adequate, deciduous where there is a dry season. Its leaves are large, arrow-shaped, and dark green. The flowers are produced in a spadix surrounded by a large white spathe, giving the plant its distinctive calla lily appearance. The spadix is yellow and bears numerous tiny flowers. The plant can grow to 1-3 feet tall and wide.
Companion planting
Calla lilies thrive in moist, shady conditions and can be planted alongside other moisture-loving plants such as ferns, hostas, and irises. Avoid planting them near plants that prefer dry, sunny conditions. Consider their invasive potential as well.
Propagation methods
Propagation can be achieved through division of rhizomes in spring or early autumn. Seeds can also be used, but they require a period of stratification and may take several years to germinate. Calla lilies can also be propagated via offsets or bulblets that form around the base of the parent plant.
History and traditions
Calla lilies have been used in floral arrangements for centuries and symbolize purity and beauty. They are often associated with weddings and funerals. In some cultures, the plant has been used medicinally to treat various ailments, although scientific evidence to support these uses is limited. The plant originates from South Africa, where it has a long history of traditional use.
Usage calendar
Flowering typically occurs in spring and early summer (March-June). Planting is best done in spring or autumn. Division of rhizomes is also best done in spring or autumn. Harvesting of flowers can be done throughout the flowering season.
