Liquidambar styraciflua - Sweet Gum
As the dark days of winter draw in, the glorious autumn colouring of Liquidambar styraciflua is a glowing beacon which has brought joy to gardeners for generations.
This large, deciduous tree is often mistaken for maple as the foliage is similar in appearance with 5-7 pointed, palmate lobes. However, the leaves of Liquidambar are arranged alternately on stems whereas the leaves of Acer species are opposite each other. The autumn colour is second to none, ranging from fiery red, orange and yellow through to sumptuous purple.
Inconspicuous male and female inflorescences are borne on the same tree in spring and are followed by globed fruits made up of many spiked seed capsules. Often known as burrballs or monkey-balls, they ripen in autumn and some can remain on the tree through winter.
Native to the warmer areas of the eastern United States and Mexico, Liquidambar was first introduced to Europe in the late 1600’s by John Banister and planted in Fulham Palace Gardens, London. Linnaeus gave its name in 1753 from the Latin liquidus meaning fluid and Arabic ambar in reference to the sweet gum which exudes from the bark when wounded; styraciflua is an old term meaning ‘flowing with styrax’ (plant resin). In Mexico, it is cultivated for this resin which is often used for incense, perfume and adhesives.
Our clients often favour Worplesdon as a clone due to its greater frost tolerance and more reliably uniform crown. The foliage has deeper lobes than other varieties and a greater intensity in its autumn colour.
