The Double Flowering Plum, also known as Prunus triloba 'Multiplex', is a deciduous shrub or small tree renowned for its profuse and stunning display of pink double flowers. Each spring, before the leaves fully emerge, the branches are adorned with masses of vibrant, double-layered blossoms that can transform a garden into a spectacular show of color. The flowers, which are about 1.5 inches in diameter, resemble small roses and are densely packed along the stems. The leaves of the Double Flowering Plum are green and oval with a serrated edge, turning to shades of yellow in the fall before they drop. The plant's bark is dark brown to reddish-brown, providing additional interest in the winter months when the shrub is leafless.
- Size: Height: 8-12 feet. Spread: 6-10 feet.
- Sunlight: Prefers full sun to partial shade. At least 6 hours of direct sunlight per day is ideal for optimal blooming.
- Soil: Thrives in well-drained, loamy soil. Can tolerate a range of soil types but prefers slightly acidic to neutral pH.
- Watering: Requires moderate watering, especially during dry spells. Keep the soil consistently moist but not waterlogged.
- Pruning: Prune immediately after flowering to maintain shape and encourage new growth. Remove any dead, damaged, or crossing branches.
- Fertilization: Apply a balanced fertilizer in early spring before new growth starts. Follow with a second application after flowering if needed.
- Pests/Diseases: Monitor for common pests such as aphids and caterpillars. Diseases can include powdery mildew and leaf spot; ensure good air circulation and avoid overhead watering to minimize risk.
- Winter Care: Generally hardy, but in colder climates, mulching around the base can help protect the roots from freezing temperatures.
