The Zazu Calla Lily presents a striking display of color and form, making it a popular choice for gardeners seeking to infuse vibrancy into their landscapes or indoor spaces. This distinct variety offers a unique aesthetic, providing an engaging focal point.
Understanding the Zazu Calla Lily
The Zazu Calla Lily (Zantedeschia ‘Zazu’) is distinguished by its captivating flower color, a blend of pink and medium brown-purple, sometimes with a subtle red-medium brown-purple secondary hue. The trumpet-shaped flowers typically range from 6.5 to 7 cm in diameter and 9 to 9.5 cm in length. These blooms emerge from an inflorescence composed of a spadix and a surrounding spathe. The foliage is often rich green, sometimes speckled with white, providing an attractive backdrop. This variety generally reaches a mature height of 20 to 24 inches (50-60 cm) and spreads about 18 inches wide, making it suitable for various garden designs and container plantings.
Planting and Growing Zazu Calla Lily
Plant Zazu Calla Lily rhizomes in spring, after the last frost and when soil temperatures have warmed sufficiently, ideally to 65°F (18°C) or higher. They thrive in full sun to partial shade; in hotter climates, provide afternoon shade. The soil should be well-draining and rich in organic matter, with a preferred pH range of 6.0 to 6.5. Bury rhizomes 3 to 4 inches (7-10 cm) deep with the “eyes” facing upwards. Space them 12 to 18 inches (30-45 cm) apart for proper air circulation and mature growth. For container planting, select pots with adequate drainage holes and plant rhizomes 1 to 1.5 inches below the soil surface, flat side up. After planting, water thoroughly to settle the soil, then sparingly until new shoots emerge to prevent rot.
Essential Care for Zazu Calla Lily
Light Requirements
Zazu Calla Lilies perform best with ample light, preferably full sun to partial shade. In cooler regions, full sun encourages vibrant blooms. In areas with intense summer heat, afternoon shade protects foliage and flowers from scorching. Adequate light also prevents weak stems and floppy plants.
Watering Needs
Maintaining consistent moisture is important for Zazu Calla Lilies, as they prefer moist, but not waterlogged, soil. During active growth and blooming, water regularly, about once a week, to keep the soil evenly moist. Allow the top 2 to 4 inches (5-10 cm) of soil to dry out between waterings to prevent root rot. Overwatering can lead to yellowing leaves and mushy stems.
Soil Preferences
Zazu Calla Lilies thrive in rich, well-draining soil high in organic matter. A soil pH between 6.0 and 6.5 is ideal for their growth. For container growing, a high-quality potting mix with good air porosity is suitable. Incorporating materials like coco peat can enhance drainage and aeration.
Fertilization Schedule
Begin fertilizing Zazu Calla Lilies in early spring when new shoots appear, using a balanced slow-release fertilizer. During active growth and flowering, apply a liquid fertilizer every three to four weeks. A balanced N-P-K ratio (e.g., 10-10-10 or 20-20-20) promotes foliage growth, root development, and flower production. Avoid excessive nitrogen, which can lead to lush foliage at the expense of blooms.
Temperature and Humidity
Zazu Calla Lilies prefer temperatures between 60°F and 80°F (15°C-27°C). They generally appreciate humid conditions, especially when grown indoors. Temperatures below 50°F (10°C) can cause dormancy. Protecting them from cold temperatures is important, as rhizomes are not frost-hardy in colder climates.
Dormancy Period
Zazu Calla Lilies typically enter dormancy in late autumn or early winter when foliage yellows and dies back. During this phase, reduce watering significantly, providing little to no water. In cold winter regions (USDA zones 3-7), rhizomes should be dug up before the first frost, dried, and stored in a cool, dry, dark, frost-free environment at 50°F to 60°F (10°C-15°C). Container-grown plants can be moved indoors to a cool, dark location.
Troubleshooting and Common Issues
Zazu Calla Lilies are generally resilient, but can encounter common problems. Yellowing leaves often indicate overwatering or nutrient deficiency; ensure proper drainage and adjust watering frequency. A lack of blooms might be due to insufficient light, improper fertilization, or inadequate dormancy. Increase light exposure and adjust feeding. While relatively pest-resistant, occasional issues with aphids or root rot can occur. Root rot is caused by overly wet soil, emphasizing the importance of well-draining soil and careful watering.
Propagation and Division
Propagate Zazu Calla Lilies by dividing their rhizomes during dormancy, typically in late winter or early spring before new growth begins. Carefully dig up the rhizome clump and gently separate it into smaller sections, ensuring each has at least one “eye” or growth point. Replant these divisions at the appropriate depth and spacing, following initial planting guidelines.
