Prunus ‘Kwanzan’ (Japanese Flowering Cherry)
Japanese Flowering Cherry 'Kwanzan', Prunus 'Kwanzan', Prunus 'Sekiyama'Prunus ‘Kwanzan’, also known as Japanese Flowering Cherry, is an iconic ornamental tree cherished for its extravagant double-pink blossoms that create a striking display in mid to late spring. Each cluster of flowers comprises up to 30 petals, giving the tree a luxurious, ruffled appearance. Its new leaves emerge bronze and mature into glossy green before transitioning to warm yellow or orange hues in autumn, ensuring multi-seasonal interest. The tree’s upright, vase-shaped crown eventually broadens with age, making it a graceful addition to any landscape.
Originating in Japan, this flowering cherry thrives in USDA hardiness zones 5–9. It reaches a mature height of 15–25 feet with a similar spread, making it ideal for small gardens, streetscapes, or as a focal point in larger landscapes. Though it does not bear fruit, its showy flowers and elegant form more than compensate, providing unparalleled beauty without the mess of falling cherries.
Care Instructions for Prunus ‘Kwanzan’
- Light Requirements: Plant in full sun for the best flower production and growth. At least 6 hours of direct sunlight daily is recommended.
- Soil Needs: Prefers well-draining, fertile soil with a slightly acidic to neutral pH. Amend heavy clay soils with organic matter to improve drainage.
- Watering: Water deeply and regularly during the first growing season to establish roots. Once established, it tolerates occasional dry periods but benefits from supplemental watering during prolonged droughts.
- Pruning: Perform pruning in late winter or early spring to remove dead, diseased, or crossing branches. Avoid heavy pruning as this may affect blooming.
- Fertilization: Apply a slow-release, balanced fertilizer in early spring to support flowering and foliage health. Avoid over-fertilization, which can lead to excessive foliage growth at the expense of blooms.
- Winter Care: Mulch around the base to insulate roots during winter and protect against temperature fluctuations.
- Disease and Pest Management: Monitor for pests such as aphids or issues like canker or leaf spot. Ensure proper air circulation and sanitation to minimize risks.
