Ranunculus ‘Cloni Success’ is a premium cultivar bred through tissue culture techniques to enhance qualities like flower size, color intensity, and vase life. It is especially valued for its ornamental use in gardens and as cut flowers. The blooms are large, double-layered, and available in striking colors, such as ivory, blush pink, and other pastels. The flowers feature a delicate, ruffled appearance with sturdy stems, making them ideal for floral arrangements.
This cultivar thrives in cooler climates and has a long flowering period when well-cared for. It is especially suitable for USDA hardiness zones 8–10, though it can be grown in other zones with careful seasonal adjustments.
Characteristics
- Flower Size and Form: The flowers of the ‘Cloni Success’ Ranunculus are notably large, often measuring 3 to 5 inches across. They are fully double, with numerous layers of petals, giving them a lush, pom-pom-like appearance. The flowers resemble small peonies or roses in structure.
- Color Range: This series is celebrated for its broad color spectrum, including vibrant and deep tones not commonly found in other ranunculus varieties. Colors can include deep reds, purples, oranges, yellows, pinks, and whites, with some varieties showcasing bicolored petals or unique color transitions.
- Stem: ‘Cloni Success’ ranunculus have sturdy, upright stems that can support the weight of their large blooms, making them excellent for cut flower arrangements.
- Foliage: The leaves are typical of ranunculus, deeply lobed, providing a nice contrast to the flowers, but the focus is primarily on the blooms themselves.
Cultivation
Planting:
- Tubers: These ranunculus are grown from tubers. Soaking the tubers for a few hours before planting can improve sprouting, especially if the tubers are dry when received.
- Planting Time: In mild winter areas, plant in the fall; in colder climates, early spring is better to avoid frost damage.
- Depth and Spacing: Plant the tubers about 1-2 inches deep, with the ‘claws’ facing downwards, spacing them 4-6 inches apart to allow for growth and good air circulation.
Soil: They require well-drained soil enriched with organic matter. A soil mix that retains moisture but doesn’t stay soggy is ideal. Sandy loam or loamy soil with added compost works well.
Watering: Regular watering is necessary, especially during the growing season. The soil should be kept moist but not waterlogged. After the plants have established, they can tolerate a slight drying out between waterings but prefer consistent moisture.
Light: Full sun is preferred, but in very hot climates, some afternoon shade can prevent the blooms from fading or the plant from stressing.
Temperature: These ranunculus thrive in temperatures above 50°F (10°C). They are sensitive to frost, so protection might be needed in colder climates or they should be grown as an annual.
Fertilization: Use a balanced, slow-release fertilizer at planting time. Once growth starts, a liquid fertilizer can be applied biweekly to encourage blooming. Avoid over-fertilizing with nitrogen, which can lead to leaf growth at the expense of flowers.
Pest and Disease Management: They can be susceptible to aphids, slugs, and snails. Also, watch for fungal issues like powdery mildew, particularly in humid or overly wet conditions. Ensure good air circulation to prevent these problems.
Cut Flower Cultivation: For cut flowers, harvest when the blooms are just starting to open, and cut the stems at an angle. They have a good vase life, often lasting over a week with proper care.
Aftercare: After blooming, allow the foliage to die back to nourish the tuber for the next season. In colder climates, lift the tubers, dry them, and store them in a cool, dry place until it’s time to replant.
