Prepare to be captivated by the alluring beauty of Zantedeschia hybrids, a captivating group of flowering plants that encompasses a vibrant spectrum of colors, shapes, and sizes. These exquisite plants, commonly known as calla lilies, grace gardens and homes worldwide, exuding an aura of elegance and charm.

Origin and Classification

Genus Zantedeschia

Zantedeschia hybrids belong to the genus Zantedeschia, a group of perennial herbaceous plants native to southern Africa. The genus comprises eight recognized species, each contributing to the development of the captivating hybrids we admire today.

Hybrid Classification

Zantedeschia hybrids are classified into two main categories based on their parentage:

• Elliott Hybrids: Created by crossing Z. elliottiana with other species, these hybrids are characterized by their vibrant yellow, orange, and pink blooms.
• Rehmannii Hybrids: Originating from a cross between Z. rehmannii and other species, these hybrids boast an array of stunning colors including blues, purples, and blacks.

Growing Zantedeschia Hybrids

Climate and Hardiness

Zantedeschia hybrids prefer warm, humid climates and are typically hardy in USDA hardiness zones 8-11. In colder regions, they can be grown as annuals or lifted and stored over winter.

Soil Requirements

These plants thrive in well-drained, humus-rich soil with a pH between 6.0 and 7.0. Avoid waterlogged soils, as they can lead to root rot.

Sunlight and Water

Zantedeschia hybrids prefer bright, indirect light. However, they can tolerate full sun in cooler climates. Water regularly, keeping the soil consistently moist but not soggy.

Propagation

Division

The easiest method of propagation is by division. In spring, carefully dig up the plant and separate the rhizomes (underground stems). Replant the divisions in well-drained soil.

Seeds

Zantedeschia hybrids can also be grown from seeds. However, it is important to note that seedlings may not be true to the parent plant. Sow seeds in a warm, moist seedbed and transplant seedlings once they have developed several leaves.

Varieties

The world of Zantedeschia hybrids is vast and diverse, offering a wide range of varieties to choose from, each with its own unique charm.

Uses and Care

Cut Flowers

To extend the vase life of cut Zantedeschia flowers, remove any yellow pollen from the spadix (central stalk) and cut the stems at a sharp angle. Change the water every few days to prevent bacteria buildup.

Container Culture

Zantedeschia hybrids can be grown successfully in containers. Choose a pot with drainage holes and use a well-draining potting mix. Water regularly and fertilize monthly during the growing season.
