The Golden Calla Lily is a popular ornamental plant known for its distinctive golden color and elegant form. These beautiful blooms are often seen in gardens and make exceptional cut flowers. Their striking appearance adds sophistication to any setting.
Golden Calla Lily Characteristics
The Golden Calla Lily is recognized by its golden-yellow spathes, which are modified leaves encircling the true flowers. These spathes form a graceful, trumpet-like shape. The plant’s dark green leaves are often speckled with lighter dots. Golden Calla Lilies reach a height of 1 to 2 feet, displaying an upright growth habit.
Planting Golden Calla Lilies
Planting Golden Calla Lilies requires selecting the right location and timing. The ideal time to plant these rhizomes is in spring, after the last frost and when the soil has warmed. Golden Calla Lilies thrive in full sun to partial shade; morning sun and afternoon shade are preferable in hotter climates to prevent leaf scorch. They require well-draining soil rich in organic matter, such as compost. Position rhizomes about 4 inches deep and 12 inches apart, ensuring growing tips face upwards. Cover with soil and water thoroughly.
Ongoing Care for Golden Calla Lilies
Consistent moisture is important for Golden Calla Lilies, but avoid overly wet conditions to prevent root rot. Water once a week, allowing the top inch of soil to dry between sessions. Golden Calla Lilies perform best in partial sun. While they tolerate full sun, prolonged intense afternoon sun can lead to leaf discoloration or faded flower color. Apply a slow-release fertilizer at planting for initial growth. A balanced liquid fertilizer can be applied monthly during the flowering period. These plants prefer temperatures between 60 to 80 degrees Fahrenheit and appreciate humid conditions. Remove spent blooms by cutting flower stems at their base to encourage new flowers. Also, remove any yellowing or damaged leaves to maintain plant health.
Dormancy and Winter Protection
Golden Calla Lilies are tender perennials that enter dormancy, especially in colder climates (below USDA Zone 8). As autumn approaches, prepare the plant for dormancy by gradually reducing watering and ceasing fertilization. Once foliage yellows and dies back, typically after the first frost, cut it down to 2-4 inches above soil level. In regions with cold winters (USDA Zones 7 and below), dig up rhizomes before the ground freezes. Brush off excess soil and allow rhizomes to dry and cure in a warm, dry place for several days to a week. Store them in a cool, dark, dry environment where temperatures remain between 50-59 degrees Fahrenheit. Placing them in a paper bag or a box filled with peat moss or dry straw helps prevent mold during storage.
Troubleshooting Common Golden Calla Lily Problems
Golden Calla Lilies can exhibit common issues. Yellowing leaves often indicate overwatering, which can lead to root rot. Conversely, yellowing can also signal a nutrient deficiency, such as a lack of nitrogen. Ensure proper drainage and allow topsoil to dry between waterings to prevent root rot. A lack of blooms might suggest insufficient light or inadequate fertilization. Provide appropriate light exposure and a balanced feeding regimen during the growing season to encourage flowering. Pests like aphids, spider mites, and mealybugs can infest Golden Calla Lilies, often found on the undersides of leaves. Regular inspection and treatment with insecticidal soap or neem oil can manage these infestations.
Important Safety Information
Golden Calla Lilies are toxic if ingested. The plant contains calcium oxalate crystals, which can cause irritation and a burning sensation in the mouth, tongue, and throat. Symptoms of ingestion include swelling, excessive drooling, difficulty swallowing, and gastrointestinal upset. Keep Golden Calla Lilies out of reach of children and pets. Wearing gloves when handling the plant can also prevent skin irritation.
