Chinese Sweetgum

The Liquidambar formosana, or Chinese Sweetgum, is a large deciduous tree grown almost entirely for its autumn: three-lobed leaves that emerge purple-bronze in spring, mature to deep green, then turn through crimson to purple before falling. Mature trees reach 20 to 40 metres in habitat and 15 to 25 metres in most plantings.
It is a park and boulevard tree rather than a small-garden one, and it wants a deep, moist, slightly acidic soil to give the colour it is planted for.
The Chinese Sweetgum is planted for autumn colour at a scale that only a large deciduous tree can deliver.
