“`html

In the realm of flowers, the Calla lily stands out as an enigmatic beauty, its trumpet-shaped blossoms and vibrant colors captivating the senses. Among the many varieties of Calla lilies, the Calla Odessa Black emerges as a true masterpiece, captivating with its deep, velvety black blooms. This elegant flower holds a special place in the hearts of flower enthusiasts, making it a sought-after choice for both indoor and outdoor adornment.

Origins and History

The Calla Odessa Black, also known as the “Black Magic” Calla lily, is a hybrid cultivar developed by renowned Dutch plant breeder Arie Pieter Segers in the late 20th century. Segers crossed the dark purple ‘Swazi Warrior’ lily with a mysterious black-flowered species from Africa, creating a Calla lily that possessed an unparalleled, deep black hue.

Physical Characteristics

Flowering

The Calla Odessa Black produces striking, trumpet-shaped flowers that typically measure 5-7 inches in diameter. Unlike other Calla lilies, which often exhibit a single bloom per stem, the Odessa Black displays multiple flowers gracefully cascading from a central stem. The velvety black spathes, the modified leaves that envelop the flower’s central spadix, unfurl to reveal a contrasting, vibrant yellow spadix that adds a touch of brilliance.

Foliage

Complementing the dramatic flowers are the lush, dark green leaves. Arising from the base of the plant, the lance-shaped leaves feature a glossy surface and exhibit a rich, almost black coloration, further enhancing the plant’s overall dark aesthetic.

Height and Spread

Calla Odessa Black is a relatively compact plant, typically reaching a height of 18-24 inches with a spread of 12-18 inches. Its compact size makes it suitable for a wide range of gardening applications, including borders, containers, and cut flower arrangements.

Cultural Requirements

Light

Calla Odessa Black thrives in bright, indirect light. While it can tolerate partial shade, it produces the most abundant blooms when exposed to ample sunlight. Protect the plant from harsh, direct sunlight, as it can scorch the leaves.

Soil

Well-drained, fertile soil is essential for optimal growth. Calla lilies prefer a slightly acidic soil pH ranging from 5.5 to 6.5. Amend the soil with organic matter, such as compost or peat moss, to improve fertility and drainage.

Water

Consistency is key when watering Calla Odessa Black. Water deeply and regularly, especially during the flowering season. Allow the top few inches of soil to dry out between waterings to prevent overwatering.

Fertilization

Fertilize the plant monthly during the growing season with a balanced liquid fertilizer. Avoid over-fertilizing, as it can lead to leaf burn.

Propagation

Calla Odessa Black can be propagated through division or from root cuttings. Division is the preferred method, as it is less labor-intensive and provides more vigorous plants.

Division

1. Carefully dig up the plant in the fall or spring.
2. Divide the clump into smaller sections, each with a growing point and roots.
3. Replant the divisions immediately in prepared soil.

Root Cuttings

1. Carefully remove a healthy root from the base of the plant.
2. Cut the root into 2-3 inch segments.
3. Insert the segments into a pot filled with moist, well-draining soil.
4. Keep the pot warm and moist. New plants should emerge within a few weeks.

Pests and Diseases

Calla Odessa Black is generally resistant to pests and diseases. However, it can be susceptible to aphids, spider mites, and root rot.

• Aphids: Treat with insecticidal soap or neem oil.
• Spider mites: Increase humidity around the plant and encourage natural predators, such as ladybugs.
• Root rot: Avoid overwatering and provide proper drainage. Remove infected plants immediately.
