  • circleLife cycle

    The Zantedeschia 'Purple Moon', commonly known as a purple calla lily, starts its life cycle as a rhizome, which is a type of underground stem that stores energy for the plant. When conditions are favorable, typically in early spring, the rhizome sprouts and produces shoots, which grow into lush foliage and the characteristic funnel-shaped purple flowers. After flowering, which can last several weeks, the plant enters a period of pollination, often with the help of insects, and may produce seeds if the flowers are successfully pollinated. Following the flowering stage, the calla lily enters a period of senescence in late summer to autumn; the leaves yellow and die back as the plant begins to go dormant. During dormancy, the plant conserves energy within the rhizome throughout the winter, until the cycle begins anew with the next growing season. If conditions are not ideal for growth, the rhizome can remain dormant underground for an extended period until favorable conditions return.

      Spring-Early Summer

    • Zantedeschia 'Purple Moon', commonly known as a variety of Calla Lily, is generally propagated during its dormancy period, which falls in the late fall or early winter. The most popular method of propagation for Calla Lilies is by dividing their rhizomes. These underground structures store energy and can be separated to create new plants. When propagating, it is essential to use a sharp, sterile knife to divide the rhizomes into sections, ensuring that each section has at least one growth node or eye. After cutting, the sections can be left to dry for a day to let the cut areas callous over, reducing the risk of rotting. The individual rhizome sections can then be planted about 3 to 4 inches (approximately 7.6 to 10 centimeters) deep in well-draining soil with the eyes facing upwards. After replanting, water the soil thoroughly to help establish the new plants.
