Worplesdon Sweetgum

Worplesdon is a named sweetgum with a pyramidal crown and deeply divided, maple-like leaves that color richly in autumn. It grows into a large landscape tree; allow space for a mature height of roughly 40–50 feet and a spread of about 26–39 feet. ## Seasonal character The [RHS Worplesdon profile](https://www.rhs.org.uk/plants/245964/liquidambar-worplesdon/details) describes a branching pyramidal tree with narrow-lobed, rich green foliage that turns orange and yellow, followed by spiky fruit capsules. Van den Berk’s exact-cultivar profile describes apricot through orange-red autumn color and lists a 1968 selection by George Jackman at Worplesdon Nursery in England; it gives an eventual height of 12–15 m and width of 8–12 m ([Worplesdon cultivar profile](https://www.vdberk.com/trees/liquidambar-styraciflua-worplesdon/)). ## Siting and growth Plant in full sun or partial shade and moist, well-drained soil. The [RHS profile](https://www.rhs.org.uk/plants/245964/liquidambar-worplesdon/details) recommends neutral to acidic soil and notes that full sun gives the best autumn color. Sweetgum works as a specimen or shade tree in parks and larger gardens, but its scale and surface roots make it a poor fit beside small patios or narrow walks. The RHS hardiness rating is based on UK conditions and is not a USDA zone. ## Maintenance Water during establishment and extended dry spells, then maintain an evenly moist root zone without waterlogging. Keep the central leader intact and remove dead or damaged branches with selective pruning. Expect spiny seed capsules; site the tree away from areas where their seasonal fall would create a nuisance. Leave room for the crown and roots rather than trying to hold this large tree to a small space.
