Liquidamber styraciflua ‘Slender Silhouette’ (Columnar Sweet Gum)

A stunning columnar tree, 12 x 3 metres over 20 years, with fresh green summer leaves and flaming autumn colours. Native to Mexico and Mesoamerica, the tree grows naturally both in mountainous regions and riverside or swampy areas.

Full sun to partial shade, any aspect, any soil that is moist but well drained. A thoroughly established tree can tolerate occasional spells of both very wet or very dry conditions.

N.B. When clipping several plants with the same tool, have a bucket containing a 5% bleach solution and swish your blades around for 30 seconds between plants to sterilise them. This will help avoid the chance of cross contamination of disease.

As with all woody plants, plant high, exposing as much of the taper at the base of the trunk as possible. Allowing soil to accumulate round the base of a tree can be fatal. Keep very well watered when first planted.

General Point about Plant Hardiness: The commonly held belief that it's better to 'plant small' is perfectly true with herbaceous plants, but not necessarily true with woody plants. They need some 'wood' on them to survive severe cold - so plants of marginal hardiness in very cold areas should really be planted LARGER, rather than smaller, wherever possible.
