Overview

Calla lilies, also known as Alcatraz, are captivating perennials renowned for their elegant, trumpet-shaped blooms and stately foliage. With over 30 species and numerous cultivars, these lilies offer a diverse array of colors and sizes, making them popular garden plants, cut flowers, and floral arrangements.

Zantedeschia aethiopica, commonly known as the “White Calla Lily” or “Alcatraz,” is the most recognizable species of calla lily. Native to South Africa, this plant is particularly striking with its pristine white bracts that form a distinctive funnel-like shape. Its name, “Alcatraz,” originates from the Spanish word for “Pelican,” referring to the perceived resemblance of its blooms to the bird’s beak.

Characteristics

Foliage

Calla lilies display lush, arrow-shaped or heart-shaped leaves that emerge from the base of the plant and are arranged in a fan-like manner. The leaves vary in size and color depending on the species, ranging from deep green to variegated with white or cream. The leaves of the White Calla Lily are large, glossy, and a vibrant emerald green.

Flowers

Calla lilies produce trumpet-shaped flowers called “spathes.” The spathe is a modified leaf that surrounds the true flowers, which are tiny and arranged on a central spadix. In the White Calla Lily, the spathe is pristine white, giving the flower its distinctive appearance. The spadix is yellow and extends beyond the spathe, adding a vibrant contrast.

Height and Size

Calla lilies exhibit a range of heights and sizes. The White Calla Lily is typically a larger cultivar, reaching heights of up to 3 feet (90 cm). Smaller species, such as Zantedeschia rehmannii, remain more compact, standing around 12 inches (30 cm) tall.

Cultivation

Hardiness and Climate

Calla lilies are generally hardy in USDA zones 8-10. In colder climates, they should be grown as annuals or overwintered indoors. They prefer full sun to partial shade and well-drained soil.

Planting

Calla lily bulbs should be planted in the spring, pointy side up, with the top of the bulb just below the soil surface. Water deeply after planting.

Watering and Fertilizing

Calla lilies require consistent moisture, especially during the growing season. Water deeply and regularly, allowing the soil to dry out slightly between waterings. Fertilize monthly with a balanced liquid fertilizer.

Propagation

Calla lilies can be propagated by dividing the bulbs in the spring or fall. Carefully lift the plant and separate the bulbs, replanting them immediately.

Uses

Garden Plants

Calla lilies add elegance and sophistication to gardens with their stately foliage and striking blooms. They can be planted in borders, containers, or as accent plants.

Cut Flowers

Calla lilies are highly prized as cut flowers due to their long-lasting blooms and elegant appearance. They are often used in wedding bouquets, arrangements, and floral centerpieces.

Symbolism

Calla lilies hold cultural significance in many societies. In Victorian times, the White Calla Lily symbolized purity and innocence. In some cultures, they are associated with death and mourning.

Toxicity

It is important to note that calla lilies are considered slightly toxic to humans and pets. The plant contains calcium oxalate crystals, which can cause irritation if ingested. It is recommended to avoid consumption of any part of the plant.

Troubleshooting

Leaf Yellowing

Yellowing leaves can indicate overwatering or nutrient deficiency. Adjust watering frequency and fertilize regularly.

Brown Tips on Leaves

Brown tips on leaves may be caused by underwatering or excessive sunlight. Increase watering and move the plant to a location with partial shade.

Blooming Problems

Calla lilies may fail to bloom due to insufficient sunlight, inadequate fertilization, or overwatering. Ensure adequate light exposure, fertilize monthly, and adjust watering frequency.
