Plum Calla Lilies: Unveiling the Allure of Arum Lily Splendor

An Introduction to Plum Calla Lilies

Plum calla lilies, scientific name Zantedeschia aethiopica ‘Plum Pleasure’, are captivating ornamental plants that belong to the Araceae family. These striking flowers emanate an air of elegance and sophistication, making them a cherished choice for gardens and floral arrangements alike.

Plum calla lilies are indigenous to the marshy regions of South Africa and were introduced to the world by European explorers in the 17th century. Today, these captivating plants can be found gracing gardens and interiors across the globe.

Physical Characteristics

Plum calla lilies are distinguished by their:

Elegant Spathe

The most notable feature of calla lilies is their trumpet-shaped spathe, which emerges from a central spadix. The spathe, which is essentially a modified leaf, envelops the spadix and comes in a stunning array of colors, including deep purple-plum in the case of ‘Plum Pleasure.’ The spathe is the element that gives the plant its characteristic calla lily silhouette.

Erect Spadix

Nestled within the spathe is the spadix, a fleshy structure that bears tiny flowers. In plum calla lilies, the spadix is a vibrant yellow hue, creating a striking contrast against the deep purple-plum spathe.

Sturdy Stems

Plum calla lilies boast sturdy, erect stems that can reach heights of up to 2 to 3 feet (60 to 90 cm). The stems provide ample support for the large, showy spathes, ensuring the plant’s graceful upright posture.

Glossy Foliage

Accompanying the showy blooms are arrowhead-shaped leaves that exude a deep green hue. The leaves are glossy and spear-like, adding to the overall aesthetic appeal of the plant.

Cultivation

Growing plum calla lilies is a rewarding endeavor that can bring a touch of exotic elegance to your garden. Follow these tips for successful cultivation:

Hardiness and Climate

Plum calla lilies thrive best in USDA hardiness zones 8 to 11. In colder regions, they can be grown as annuals or potted and brought indoors during the winter months.

Soil Requirements

These plants prefer moist, well-drained soil that is rich in organic matter. Amending the soil with compost or peat moss can improve its fertility and drainage.

Light Conditions

Calla lilies appreciate bright, indirect light. Avoid planting them in areas with intense direct sunlight, as this can scorch the leaves.

Watering Needs

Plum calla lilies require regular watering, especially during the growing season. Keep the soil consistently moist but not waterlogged. Allow the top inch of soil to dry out slightly between waterings.

Fertilization

Feed plum calla lilies monthly during the growing season with a balanced liquid fertilizer. This will provide the essential nutrients they need for optimal growth and flowering.

Pests and Diseases

Plum calla lilies are generally not prone to serious pests or diseases. However, they can occasionally be affected by:

Aphids

These small, soft-bodied insects can suck sap from the plant, causing stunted growth and yellowing leaves. Control aphids by using insecticidal soap or spraying the plant with a strong stream of water.

Slugs and Snails

These pests feed on the leaves of calla lilies. To deter them, apply slug and snail bait around the plants or create a barrier of diatomaceous earth.

Bacterial Soft Rot

This disease can cause soft, watery lesions on the plant’s stems and leaves. Remove and destroy affected plant parts and avoid overwatering to prevent this disease.

Uses of Plum Calla Lilies

Plum calla lilies are highly versatile plants with a multitude of uses:

Garden Ornamental

With their dramatic spathes and glossy foliage, plum calla lilies add a touch of exotic flair to any garden. They can be planted in borders, containers, or as a cut flower in arrangements.

Floral Arrangements

The deep purple-plum spathes make calla lilies a popular choice for bouquets and floral arrangements. They add a touch of elegance and sophistication to any occasion.

Cut Flowers

Plum calla lilies are long-lasting cut flowers that can brighten up vases for up to two weeks. To prolong their vase life, remove the pollen-bearing anthers to prevent staining.
