Introduction

The green arum lily, also known as Zantedeschia aethiopica or calla lily, is an enchanting perennial that captivates with its striking foliage and elegant flowers. With its distinct appearance and diverse applications, the green arum lily has become a beloved choice among gardeners and flower enthusiasts alike.

Botanical Characteristics

Plant Formation

The green arum lily is an upright, clump-forming, herbaceous plant that typically reaches heights of 18 to 36 inches. Its sword-shaped leaves emerge directly from the base, forming a dense and lush foliage.

Leaves

The most distinctive feature of the green arum lily is its leaves. These leaves are large, heart-shaped, and glossy, showcasing a deep green color with a waxy sheen. They form a funnel-shaped collar around the flower stalk, creating an architectural focal point.

Flowers

The flowers of the green arum lily are unique and enigmatic. They consist of a central spadix, a fleshy, finger-like structure, which is surrounded by a large, petal-like structure known as the spathe. The spathe is typically white or cream-colored, but can also be found in shades of pink, yellow, or even green.

Cultivation

Climate and Soil

Green arum lilies prefer warm, temperate climates and can thrive in USDA hardiness zones 8 to 11. They require well-drained, moist soil rich in organic matter. Avoid planting in heavy clay soils, as they can cause root rot.

Planting and Care

  • Plant green arum lilies in the spring or fall, approximately 6 inches deep and 12 inches apart.
  • Water regularly, especially during hot, dry weather, but allow the soil to dry out slightly between waterings.
  • Fertilize monthly with a balanced liquid fertilizer.
  • Deadhead faded flowers to encourage new growth and prevent seed formation.

Winter Care

In colder climates, green arum lilies will need protection during the winter months. Mulch around the base of the plants with organic matter, such as leaves or straw, to insulate the rhizomes. If temperatures drop below freezing, dig up the rhizomes and store them in a cool, dark place until the spring.

Uses

Landscaping

Green arum lilies make excellent border plants, adding height and drama to garden beds. Their lush foliage and showy flowers create a stunning backdrop for other plants. They can also be planted in containers or pots, adding a touch of elegance to patios or balconies.

Cut Flowers

The flowers of the green arum lily are long-lasting and make beautiful cut flowers. They are ideal for arrangements, bouquets, and wedding centerpieces. When cut, the flowers can last up to two weeks in a vase with fresh water.

Toxicity

Caution: All parts of the green arum lily are toxic to humans and animals. Ingestion can cause mouth irritation, nausea, and vomiting. Keep plants out of reach of children and pets.

Conclusion

The green arum lily is a captivating and versatile plant that offers a combination of beauty and functionality. Its elegant flowers and striking foliage make it a popular choice for gardens and cut flower arrangements. With proper care and attention, green arum lilies will thrive and provide years of enjoyment.
