Kwanzan cherry, scientifically known as Prunus serrulata 'Kwanzan', is a stunning ornamental cherry tree prized for its showy, double-petaled pink flowers and graceful form. Here are some key points about this tree:

1. Appearance: Kwanzan cherry is characterized by its abundant clusters of large, double-petaled pink flowers that bloom in early spring. The flowers create a spectacular display, covering the branches before the leaves emerge. The foliage is bronze when it first appears, turning dark green in the summer and yellow to bronze in the fall. The tree has a vase-shaped form and a spreading canopy.

2. Size: This cherry tree typically grows to a height of 15 to 25 feet with a similar spread, forming a rounded crown. Its moderate size makes it suitable for various landscape applications, including as a specimen tree, focal point, or street tree.

3. Flowers: Kwanzan cherry produces abundant, showy flowers in early spring, making it one of the most popular flowering cherry trees. The double-petaled pink flowers are highly ornamental and attract pollinators like bees and butterflies to the garden.

4. Sun and Soil Requirements: Kwanzan cherry thrives in full sun to partial shade and prefers well-drained, slightly acidic soil. It is tolerant of a range of soil types, including clay, loam, and sandy soils, but performs best in soil with good drainage.

5. Watering: While Kwanzan cherry is relatively drought-tolerant once established, it benefits from regular watering, especially during periods of prolonged dryness. Adequate moisture is essential, particularly during the tree's establishment period.

6. Pruning: Pruning is typically minimal for Kwanzan cherry. It may be necessary to remove any dead, damaged, or diseased branches and to shape the tree to maintain its desired form. Pruning is best done after flowering to avoid removing flower buds.

7. Landscape Use: Kwanzan cherry is commonly used as a specimen tree, focal point, or street tree in residential and urban landscapes. Its stunning spring flowers, graceful form, and moderate size make it a popular choice among homeowners, landscapers, and city planners.

Overall, Kwanzan cherry is a beautiful and ornamental tree prized for its showy spring flowers, graceful form, and ease of care. Whether planted as a specimen tree in a backyard, as a focal point in a garden, or along urban streetscapes, it adds beauty and elegance to the landscape throughout the spring season.
