Prunus 'Kanzan'
Kwanzan Cherry is an upright, vase-shaped ornamental tree that reaches about 35 feet tall and 30 feet wide. Its double deep-pink flowers make their main display in mid spring, giving it a strong role as a focal point rather than a background planting. Use it where its canopy can rise above lower planting layers without crowding the garden’s working space.
Space Kwanzan Cherry 25 ft apart, measured center to center (7.6 m).
The mature spread is about 30 ft (9.1 m), so plants set at that distance grow together into a closed canopy.
Treat 25 ft as a planning baseline — cultivar and local growing conditions shift the final footprint.

Give Kwanzan Cherry a prominent open position near a patio, along a broad street verge, or at the end of a long bed where the spring canopy can be seen from several viewpoints. Keep the trunk out of tight foundation beds and away from narrow walks; the tree needs a clear approach for pruning and for tending the planting beneath it. Its upright young form can frame an entry or path, while the mature crown needs room to spread outward.
Plant trees 25 feet apart, center to center, so each has its own canopy zone as it matures. A 30-foot-wide crown can extend roughly 15 feet from the trunk, so reserve more than the planting interval where a path, wall, drive, or neighboring tree would occupy that outer canopy space. Avoid using the area directly beneath the eventual crown for tall permanent shrubs or structures that would block access.
Place this tree in full sun and provide moderate moisture, with well-drained soil rather than a site that stays wet. A loamy planting area can accommodate it well, but good drainage is especially important when selecting a low point in the yard or a bed beside hardscape. Leave open air around the canopy instead of enclosing it between dense evergreen screens or closely packed trees.[1][2]
The deep-pink bloom period falls in mid spring, before the canopy becomes the larger visual feature of the planting. Set it where spring color can be appreciated from windows, seating, or the main route through the garden, but do not rely on that period alone when planning the surrounding bed. Lower plants should retain clear access around the trunk after flowering has passed.
Reserve an access route for routine inspection and pruning. Flowering cherries can face insect and disease problems, including leaf diseases, dieback, borers, and scale, so a crowded or poorly drained location can complicate long-term care. Keep enough clearance from fences, walls, and neighboring canopies to work around the tree without forcing access through planted beds.[1][3]
