Zantedeschia ‘Sunclub®’: A Burst of Sunshine in Bloom
Zantedeschia ‘Sunclub®’, commonly known as the Sunclub Calla Lily, is a dazzling cultivar of Zantedeschia rehmannii, a species celebrated for its compact stature and exceptional adaptability. Bred by Dümmen Orange, this cheerful calla lily makes a striking impression in containers, garden beds, and floral arrangements alike. Its vibrant yellow blooms rise above lush, subtly spotted foliage, bringing warmth and radiance to any outdoor space. As a member of the Araceae family, ‘Sunclub®’ shares the distinctive funnel-shaped spathes and robust tropical appeal typical of calla lilies.
The Glow of Sunclub Calla Lily
From midsummer to early fall, Zantedeschia ‘Sunclub®’ bursts into bloom with large, lemon-yellow flowers that seem to glow from within. Each flower features a dark, central throat that adds a hint of drama, while the surrounding petals flare like golden trumpets. These are not just ordinary garden blooms—they’re luminous highlights that brighten borders, patios, and balconies. The leaves are deep green with faint silver spotting, providing a beautiful contrast to the vibrant floral display.
The upright growth habit and clean, architectural lines of this plant add to its decorative value. Reaching heights of 45–60 cm (18–24 inches) with a similar spread, ‘Sunclub®’ offers a manageable size for mixed containers or smaller garden plots without sacrificing visual impact.
How to Grow Zantedeschia ‘Sunclub®’
Zantedeschia ‘Sunclub®’ is surprisingly easy to grow, as long as its basic needs are met. This warm-weather perennial thrives with sun, consistent moisture, and good drainage. In cooler zones, it performs beautifully as a seasonal container plant or summer bedding flower.
Light
For best flowering, provide full sun—at least 6 hours per day. In very hot climates (zones 9–10), light afternoon shade can prevent leaf scorching and help prolong bloom time. Indoors, place containers in a spot with bright, indirect light, such as a west-facing window.
Soil
The ideal soil for ‘Sunclub®’ is loose, fertile, and drains well. A slightly acidic to neutral pH (6.0 to 7.0) supports healthy growth. Amend heavier soils with compost, peat moss, or coarse sand to improve structure and drainage. When planting in containers, choose a high-quality potting mix formulated for bulbs or tropical plants.
Watering
Sunclub calla lilies need consistently moist soil, especially during active growth and flowering. Water when the top 2.5 cm (1 inch) of soil feels dry, applying deeply to reach the root zone. Avoid wetting the leaves to reduce the risk of fungal diseases. In containers, ensure that excess water can drain freely and never let the pot sit in water.
Fertilizing
Feed ‘Sunclub®’ every 2–3 weeks during the growing season with a balanced liquid fertilizer (such as 10-10-10), diluted to half strength. Once the flowers emerge, you can switch to a formula with higher potassium to support prolonged blooming. Stop feeding after the plant finishes flowering.
Zantedeschia ‘Sunclub®’ in the Garden
Whether grown in a container or directly in the soil, this Sunclub Calla Lily brings bold, tropical energy to landscapes. Its upright shape makes it a natural focal point for entryways, poolside planters, or mixed borders. For a vibrant summer display, combine it with trailing foliage, purple petunias, or ornamental grasses. Its deer- and pest-resistance also makes it a reliable performer in rural and urban gardens alike.
Thanks to its stunning color and long-lasting blooms, Sunclub Calla Lily is also a florist favorite. The strong, upright stems and pristine flowers make ideal cut flowers for fresh arrangements, wedding bouquets, or vibrant centerpieces.
Hardiness and Overwintering
Zantedeschia ‘Sunclub®’ is hardy in USDA zones 8 to 10. In these warmer climates, it can be grown as a perennial and left in the ground year-round. In zones 3 to 7, it must be treated as a tender bulb. After the first frost, lift the rhizomes and store them indoors to replant in spring.
How to overwinter:
- Dig carefully: Lift rhizomes before frost hits.
- Trim and clean: Cut back the foliage to 2–5 cm (1–2 inches), rinse off soil, and allow them to dry in a warm, well-ventilated place (65–75°F / 18–24°C) for 2–3 days.
- Store: Keep in dry peat or sand at 10–15°C (50–60°F) in a cool, dark space.
Propagation
Propagate Zantedeschia ‘Sunclub®’ by dividing rhizomes. Wait until spring, after the rest period. Separate healthy, firm rhizomes with at least one visible growth point (“eye”) and replant in fresh, well-draining soil.
Pests, Diseases, and Troubleshooting
This cultivar resists most pests, but occasional aphids or spider mites may appear—especially on indoor or greenhouse-grown plants. Treat infestations promptly with insecticidal soap or neem oil.
Overwatering is the most common cause of problems. Symptoms such as yellowing leaves or drooping stems may signal root rot. Reduce watering, improve drainage, and remove affected parts of the plant.
After blooming, Zantedeschia naturally enters a dormant period. During this time, leaf dieback is normal. Reduce watering and let the plant rest before restarting the growth cycle in spring.
Caution: Toxicity
All parts of the Zantedeschia plant are considered toxic if ingested and can cause irritation to the skin or eyes. Always wear gloves when handling and wash hands afterward. Keep out of reach of pets and children.
