#Aesculus

• Aesculus — A genus of woody plants, deciduous trees, and shrubs belonging to the Sapindaceae family (formerly Hippocastanaceae), distributed throughout the temperate regions of the Northern Hemisphere. These species are structurally characterized by palmate-compound leaves, large erect thyrsus-like inflorescences, and globose, often spiny capsular fruits containing large seeds popularly known as chestnuts.
• Aesculus hippocastanum — Scientific name of the horse chestnut, an imposing deciduous tree native to the mountainous forests of the Balkan Peninsula, widely cultivated as an ornamental plant in temperate zones. It is structurally recognized by its globose crown, white flowers with red or yellow spots grouped in erect panicles, and spiny capsules containing seeds rich in aescin, a substance extensively used in pharmacology to treat venous disorders.
• Aesculus octandra — Scientific name of the yellow buckeye, a large deciduous tree species native to eastern North America, structurally recognized by its yellow to yellowish-green tubular flowers grouped in erect panicles and smooth, completely spineless capsular fruits. The wood of this tree is light and soft, used in carpentry, and the plant is highly valued in horticulture for its resilience and spectacular autumn coloration.
• Aesculus parviflora — Scientific name of the bottlebrush buckeye, a large deciduous shrub species native to the southeastern United States, structurally recognized by its wide, suckering habit and extremely long, cylindrical panicles filled with white flowers featuring long, prominent, reddish stamens. It is widely cultivated as a solitary ornamental plant in parks due to its spectacular mid-summer blooms.
• Aesculus pavia — Scientific name of the red buckeye, a small deciduous tree or shrub species native to the southeastern United States, structurally recognized by its erect inflorescences with bright red tubular flowers and smooth, spineless capsules containing seeds rich in toxic saponins. It is widely cultivated as an ornamental plant in parks and gardens due to the vibrant color of its spring blooms and its ability to attract hummingbirds.
• Aesculus x carnea — Scientific name of the red horse chestnut, a fertile hybrid arising from the cross between Aesculus hippocastanum and Aesculus pavia. This medium-sized deciduous tree is structurally recognized by its dense crown, dark green palmate-compound leaves, spectacular pinkish-red flowers grouped in large erect panicles, and slightly prickly round capsules, being a highly valued avenue tree in global urban landscaping.
