Katsura Tree

Cercidiphyllum japonicum

Katsura Tree is a long-lived shade tree for a generous, permanent opening in the landscape. It reaches about 50 feet tall and 30 feet wide, creating a substantial canopy rather than a small ornamental accent. Heart-shaped foliage carries the main display: leaves emerge with spring color, settle into summer green, then turn apricot in fall, when fallen leaves bring a caramel-like fragrance to the ground layer.

Katsura Tree spacing and mature footprint

Space Katsura Tree 30 ft apart, measured center to center (9.1 m).

The mature spread is about 30 ft (9.1 m), so neighboring plants just meet at maturity without crowding.

Treat 30 ft as a planning baseline — cultivar and local growing conditions shift the final footprint.

Placement and use

Use this tree as the principal canopy feature in a lawn, broad planting bed, or other large-scale part of the plan. Keep its future crown clear of roofs, overhead utilities, and closely packed smaller trees so the branching structure has room to develop. Place paths and seating outside the mature canopy edge where possible, while retaining a direct route for watering during establishment and dry spells. A sheltered location helps protect foliage from drying wind.[1][2]

Spacing and mature footprint

Set multiple Katsura Trees 30 feet apart, center to center. That interval matches the expected 30-foot mature width, so neighboring crowns will meet or lightly overlap as the trees fill in. For a single specimen, reserve a 30-foot-wide canopy zone and avoid using that space for permanent sun-dependent beds, structures, or circulation that cannot accommodate increasing shade and leaf drop over time.

Sun, water, and soil

Give it a full-sun position and moderate, consistent moisture rather than a site that repeatedly dries out. Deep, well-drained soil that stays evenly moist suits its long-term placement, especially while the root system is establishing. Build irrigation access into the plan before planting; drought can stress the foliage, and hot, dry wind can cause leaf scorch.[1][2]

Seasonal notes

Early-spring flowers arrive before the foliage but remain a quiet detail in the overall design. The larger seasonal shift comes in autumn, when the canopy turns apricot-toned and the fallen leaves add their distinctive caramel-like scent. Allow for seasonal cleanup along nearby walks, patios, and entry routes, or position the tree where leaf fall can remain part of a naturalistic ground layer.

Planning caveats

Katsura Tree is suited to USDA Zones 4 through 8. Protect the planting from strong wind and avoid sites with persistent drought stress, particularly while the tree is young. Its mature size calls for a long view: leave enough open ground for the crown to expand and avoid committing the surrounding area to plants that require uninterrupted full sun.[1][2]
