The Liquidambar styraciflua 'Slender Silhouette', commonly known as the Upright Sweet Gum, is a striking deciduous tree that adds vertical elegance to any landscape. This cultivar is particularly noteworthy for its extremely narrow, columnar growth habit, which makes it an excellent choice for small gardens, urban settings, or as a distinctive structural element in larger landscapes. Reaching a mature height of approximately 12-15 meters, the 'Slender Silhouette' maintains a remarkably slender spread of only about 1.5-2 meters, making it a space-efficient option for tight areas.

One of the standout features of the Upright Sweet Gum is its lush, star-shaped foliage, which transitions through a spectacular array of colours in the fall. Leaves turn from bright green in the spring and summer to vibrant shades of yellow, orange, red, and purple, providing a dazzling autumn display. The tree also produces small, spiky seed balls that add texture and interest throughout the year.

The 'Slender Silhouette' is quite adaptable and thrives in a variety of soil types, including loamy, sandy, and clay soils, provided they are well-drained. It prefers full sun to partial shade and is relatively low-maintenance once established, with good resistance to pests and diseases. This tree is also tolerant of urban pollution, making it a resilient choice for city environments. Whether used as a focal point, a privacy screen, or a vertical accent, the Liquidambar styraciflua 'Slender Silhouette' is sure to enhance the beauty and character of any landscape.
