About this cultivar

Liquidambar formosana 'Ellen' reaches 12 to 20 metres in a garden, with a conical to rounded crown, and differs from Liquidambar styraciflua in its three-lobed leaf, which is broader, and in its purple new growth.

The foliage is dark green in summer and passes through red, orange and purple in autumn, with the colour arriving later and lasting longer than in most trees. The spherical, spiny fruits stay on the tree in winter.

It is a selection propagated by grafting, which guarantees specimens comparable with one another and reliable autumn colour, unlike seed-raised plants. It prefers full sun and moist, deep, acidic to neutral, well-drained soils; it tolerates summer heat better than the American species and responds poorly to active lime.
