Cercidiphyllum japonicum ‘Heronswood Globe’

(Dwarf Katsura Tree) A relatively recent introduction to the UK, Cercidiphyllum japonicum ‘Heronswood Globe’ is an unusual dwarf selection of katsura tree raised in America with glorious creamy-yellow to pink autumn colour.

As the leaves fall from the tree late in the year, they give off an aroma similar to burnt sugar or candy floss. An ideal choice of tree for autumn colour in smaller gardens where a traditional Cercidiphyllum might be to large!

  • Position: Sheltered area in full sun or light, dappled shade.
  • Soil: Moist but well drained, acidic soils. Will tolerate some lime but will grow better and produce more vivid autumn colour in acid soil.
  • Hardiness: Very hardy but vulnerable to late spring frosts as a young plant, although it usually recovers well. Grows best in an area sheltered from strong winds (this also allows the tree to keep its autumn colour for as long as possible).
  • Rate of Growth: Generally slow growing initially then moderate.
  • Habit: Cercidiphyllum japonicum ‘Heronswood Globe’ grows to be a small tree with a bushy, rounded crown.
    • Height: up to 6 m (20 ft)
    • Spread: 6 m (20 ft)

KATSURA TREE

In youth, this fine-textured native of China and Japan is upright and pyramidal, but it becomes more rounded with age. It tops out at around 40 feet At all ages, it has a light, dainty branch and leaf pattern. Brown bark is somewhat shaggy on old trees. Heart-shaped, 24 inches-long leaves emerge reddish purple, become bluish green in summer, then turn yellow to apricot in autumn. To enhance fall color, water less frequently in late summer. Foliage of some katsura trees smells like brown sugar on warm autumn days when leaves are falling and when new growth opens in spring.

Some specimens have a single trunk, but multiple trunks are more usual. ‘Rotfuchs’ (‘Red Fox’) leaves open dark purple. ‘Heronswood Globe’ is compact but eventually can reach 20 feet tall and wide. Weeping forms are particularly elegant; these grow about 25 feet tall and 15 feet wide and include ‘Amazing Grace’, ‘Morioka Weeping’, and Cercidiphyllum Japonicum pendulum.

Katsura Tree Care

Katsura trees need regular moisture (especially during youth) and shelter from intense sun and drying wind. No serious pest or disease problems. Mature trees need little pruning.
