Liquidambar Gumball 3/4 Standard 55 Litre Pot Stem 150cm

Liquidambar styraciflua 'Gumball' – Compact Globe-Shaped Sweetgum with Fiery Autumn Colour

Liquidambar styraciflua 'Gumball', commonly known as Sweet gum, is a slow-growing, deciduous tree prized for its naturally rounded, globe-shaped crown and breathtaking seasonal foliage. From spring through summer, the canopy is clothed in glossy, deeply lobed, star-shaped leaves of rich green, before the arrival of autumn triggers a spectacular transformation into fiery oranges, burning reds, and deep wine purples — a display that rivals any tree in the deciduous world.

Its compact, symmetrical habit, restrained growth, and minimal care demands make 'Gumball' an exceptional choice for gardeners seeking bold seasonal drama without compromising on space. Whether used as a standalone focal point, planted in formal rows, or incorporated into a mixed planting scheme, this cultivar delivers year-round structure and beauty.

Habit & Appearance

Form & foliage. 'Gumball' is distinguished by its naturally symmetrical, ball-shaped crown — a characteristic that develops reliably without the need for corrective pruning. The deeply lobed, star-shaped leaves are a defining feature of the Liquidambar genus, emerging in a fresh, bright green in spring and deepening to a rich, lustrous green through the summer months. Come autumn, the foliage ignites in a dazzling array of orange, scarlet, crimson, and purple tones, providing weeks of colour before leaf fall. Even through winter, the clean, rounded silhouette and attractively textured bark ensure this tree earns its place in the garden in every season.

Growth rate & mature size. This cultivar is slow to moderate in growth rate, eventually forming a compact, neatly rounded tree well-suited to smaller gardens, urban courtyards, formal schemes, and avenue planting. Its restrained spread means it can be used confidently in situations where a standard Liquidambar would quickly outgrow its allotted space.

Growing Conditions

Position. Plant 'Gumball' in a full sun position to achieve the densest canopy and the most vivid autumn colour. It will tolerate partial shade, though reduced light levels may diminish the intensity of the seasonal display. This cultivar shows good tolerance of urban conditions, including wind and atmospheric pollution, making it a reliable performer in city and suburban gardens alike.

Soil. Thrives in moist, well-drained soil and adapts well to a range of soil types, including clay and loam. For the richest and most intense autumn colour, a slightly acidic to neutral soil pH is preferred. Avoid shallow, chalky, or very dry soils where possible — consistently moist conditions support the healthiest growth and the most spectacular seasonal display.

Hardiness. Fully hardy across the UK (RHS H6), tolerating frost, cold winds, and typical British winter conditions without difficulty.

Care & Pruning

Watering. Water thoroughly and regularly during the first growing season to encourage strong root establishment. Once settled in, 'Gumball' develops reasonable drought tolerance, though occasional deep watering during prolonged dry spells will support healthy growth and sustain the quality of the autumn colour display.

Feeding. In fertile, well-prepared soils, supplementary feeding is rarely necessary. Where soils are sandy or nutrient-poor, applying a balanced slow-release fertiliser in early spring will promote healthy foliage and vigorous seasonal growth.

Mulching. Apply a generous layer of organic mulch — such as composted bark or garden compost — around the base of the tree each spring to retain soil moisture, suppress weed competition, and regulate soil temperature. Keep mulch clear of the trunk to avoid the risk of rot at the base.

Pruning. One of 'Gumball's greatest practical virtues is its naturally neat, self-maintaining form, which requires very little intervention. Remove any dead, damaged, or crossing branches during late winter while the tree remains fully dormant. Avoid heavy or structural pruning, as the ornamental globe shape develops most effectively when the tree is allowed to grow freely.

Design Ideas

Feature tree. Use 'Gumball' as a standalone specimen in a lawn, border, or courtyard where its precise rounded profile and spectacular seasonal colour changes can take centre stage throughout the year.

Formal & avenue planting. The consistent, symmetrical habit makes this cultivar ideal for paired plantings or repeated avenue schemes along pathways, driveways, or formal garden borders, lending rhythm, repetition, and structural elegance to the design.

Planting combinations. Pair with evergreen shrubs such as Buxus, Taxus, or Ilex to create a rich, dark backdrop that intensifies the autumn foliage display. Underplant with shade-tolerant perennials such as Heuchera, Geranium, or Epimedium for layered, multi-season interest beneath the canopy.

Urban & contemporary gardens. The compact, slow-growing nature of 'Gumball' makes it a natural choice for smaller urban gardens, patio settings, and contemporary planting schemes where clean lines, bold seasonal colour, and low
