Overview
Katsura is an elegant deciduous tree from Japan and China, prized for its delicate, rounded, heart-shaped leaves and refined pyramidal-to-rounded form. New foliage emerges reddish-purple, matures to soft blue-green, and turns shades of yellow, gold, and apricot in autumn.
Its most celebrated trait is the sweet fragrance — reminiscent of burnt sugar, caramel, or cotton candy — released by the falling autumn leaves. It makes a beautiful specimen or shade tree where soils stay moist.
How to identify it
Heart-shaped leaves and fall fragrance distinguish it:
- Leaves small, rounded, heart-shaped with scalloped margins, arranged oppositely; blue-green in summer, reddish-purple when young
- Fall color yellow to apricot-orange, accompanied by a sweet burnt-sugar scent
- Habit often multi-stemmed with a rounded or pyramidal crown; weeping cultivars exist
- Bark brown, becoming shaggy and peeling with age
- Flowers tiny and inconspicuous, appearing before the leaves; trees are dioecious
- Size 40-60 ft tall, sometimes larger
Care & growing
Needs reliable moisture, especially when young.
- Light: Full sun to partial shade
- Water: Keep soil consistently moist; young trees are sensitive to drought and may scorch
- Soil: Rich, moist, well-drained, slightly acidic soil is ideal
- Temperature: Hardy in USDA zones 4-8
- Feeding: Light feeding in spring if growth is weak
- Propagation: From seed or softwood cuttings; named forms are grafted
Habitat & origin
Native to Japan and China, where it grows in moist mountain woodlands and along streams and can become a very large forest tree.
In cultivation it is a popular ornamental in temperate gardens across North America, Europe, and Asia, favored for lawns, parks, and as a moist-site specimen.
Frequently asked questions
Why does it smell like cotton candy?
As the leaves senesce and fall in autumn they release maltol and related compounds, producing a sweet burnt-sugar or caramel aroma.
Is it related to the redbud?
No, though its heart-shaped leaves resemble redbud's, the genus name Cercidiphyllum simply means 'redbud-leaved.'
Why are my katsura's leaves scorching?
It is sensitive to dry soil and heat; insufficient water, especially in young trees, causes leaf-edge scorch.
Does it need a male and female tree?
It is dioecious, but it is grown for foliage, not fruit, so a single tree of either sex is fine for ornamental use.
