Introduction

Zantedeschia yellow, commonly known as yellow calla lily, is a captivating plant that brings a vibrant splash of color to gardens and homes. Belonging to the family Araceae, these striking flowers are native to southern Africa, where they thrive in wetlands and along rivers. With their elegant trumpet-shaped blooms, glossy foliage, and versatility in cultivation, yellow calla lilies have become popular ornamental plants worldwide.

Characteristics of Zantedeschia Yellow

• Flowering: Yellow calla lilies bloom profusely during the summer months. The flowers consist of a large, showy spathe (the funnel-shaped outer part) and a central spadix (the spike-like inner part).
• Size: The height of these plants varies depending on the cultivar, ranging from dwarf varieties at 15-30 cm (6-12 inches) to taller ones that reach up to 90 cm (36 inches).
• Leaves: The foliage is large, arrow-shaped, and has a glossy surface. The leaves come in various shades of green, adding to the plant’s ornamental value.
• Tuberous Roots: Yellow calla lilies grow from underground tuberous roots, which store nutrients and moisture.

Cultivation and Care of Yellow Calla Lilies

Growing Requirements

• Light: Yellow calla lilies prefer partial shade to full sun. They can tolerate full sun in cooler climates but require protection from the intense afternoon heat in warmer areas.
• Soil: The ideal soil for these plants is well-drained, rich in organic matter, and slightly acidic to neutral.
• Moisture: Callas require consistently moist soil, especially during active growth and flowering. Avoid overwatering, as it can lead to root rot.

Planting and Care

• Planting: Plant the tuberous roots in spring after the last frost. Place them horizontally, about 10-15 cm (4-6 inches) deep and 10-15 cm (4-6 inches) apart.
• Watering: Water regularly to keep the soil moist but not soggy. Allow the top few inches of soil to dry out slightly between waterings.
• Fertilizing: Fertilize monthly during the growing season with a balanced liquid fertilizer.

Dormancy and Overwintering

• After Flowering: Once the flowers fade, gradually reduce watering until the foliage dies back naturally.
• Lifting and Storing: In cold climates, the tuberous roots need to be lifted and stored over winter to prevent frost damage. Dig them up after the foliage has dried completely and allow them to dry out in a cool, frost-free place.
• Replanting: Replant the roots in spring when the soil has warmed up again.

Uses of Zantedeschia Yellow

• Garden Display: Yellow calla lilies create a stunning visual impact in borders, containers, and along water features.
• Cut Flowers: The long-lasting blooms are popular for cut flower arrangements and bouquets.
• Symbolism: In Victorian language of flowers, yellow calla lilies symbolize gratitude and admiration.
