Kwanzan

Kwanzan, also spelled Kanzan, is a cultivar of flowering cherry (Prunus serrulata) renowned for its abundant double pink blossoms in spring. Originating in Japan, Kwanzan has become one of the most widely planted ornamental cherry varieties in temperate landscapes worldwide. It is commonly used as a focal specimen in gardens, parks, and streetscapes.

The tree is deciduous with a broad, rounded to vase-like canopy. It typically reaches about 25 to 30 feet tall and 20 to 25 feet wide (roughly 7.5–9 m by 6–8 m). The trunk and older branches are dark brown, and the leaves are oval with serrated edges. In autumn, the foliage often turns yellow to red before dropping.

Flowers are the standout feature: large, double blossoms about 2 to 3 inches across, forming a pom-pom of petals. The bloom color ranges from rose-pink to deep pink, sometimes with lighter edges. Flowering occurs in spring, often a bit later than some other cultivars, and can be prolific in favorable conditions.

Cultivation notes: Kwanzan prefers full sun and well-drained soil and is hardy in USDA zones 5 through 9. It benefits from protection against strong winds and late frosts that can damage new blooms. Moderate irrigation during the growing season and light spring fertilization support flowering and growth.

Overall, Kwanzan is valued for its showy spring display and its versatility as a specimen or accent tree in temperate gardens and urban plantings.
