Aesculus hippocastanum is a tree.
Aesculus hippocastanum was described by Carl Linnaeus in 1753. The name is considered as validly published.
The comparatively fast-growing trees have a rounded to broadly spreading canopy and reach heights of 25 to 30 metres. The plants reach a width of 10 to more than 15 metres.
Wood and Bark
The bark is flaky and grey.
Aesculus hippocastanum is deciduous. The dark-green, digitate leaves are opposite. The leaflets are obovate and petiolate. They have entire margins and pinnate venation. They turn an attractive yellow in autumn.
Flowers and Fruits
Aesculus hippocastanum produces panicles of erect, white five-stellate flowers in May. The plants flower on older shoots. They are dioecious, pollination takes places by allogamy through animals.
The trees produce ornamental brown loculicidal capsules in autumn.
The plants form deep-reaching roots.
Aesculus hippocastanum is native to Southeast Europe.
The trees prefer a sunny situation on fresh to moist soil. The substrate should be sandy, gritty-sandy, sandy-loamy or gritty-loamy soil with a pH between 6,5 and 10. They tolerate temperatures down to -35Â°C (USDA zone 4).

Suited as avenue tree, specimen plant, greenery along roads, bee pasture, bird pasture and as plant providing shelter for birds.
Maintenance and Propagation
The plants usually require only a moderate amount of maintenance.
Pests and Diseases
Spots on leaves and withering shoots indicate an infection with anthracnose. This is a fungus that may cause the plants to die. Destroy affected parts and improve ventilation and hygiene.
Leaf blotches are a sign of a fungal or bacterial infection. Bacterial spots are rather angular and yellow-rimmed while fungal spots usually are rather rounded with an area of fruiting bodies. Destroy affected parts, additionaly apply fungizide it is is a fungal infection.
A powdery white coat on the plants indicates an infection with powdery mildew. Remove affected plants and apply a fungicide. To prevent infection improve ventilation, keep the roots moist and do not water the plants from above.
White tufts or white covering on the lower surface of the leaves indicates an infection with downy mildew. Remove affected plants and apply a fungicide. To prevent infection improve ventilation, keep the roots moist and do not water the plants from above.
