Aesculus x carnea ‘Briotii’: The Enchanting Ruby Red Horse Chestnut
Background and Family: Aesculus x carnea ‘Briotii’ is a captivating hybrid tree, resulting from the cross between Aesculus pavia, commonly known as the Red Buckeye, and Aesculus hippocastanum, or the Horse Chestnut. This exquisite tree belongs to the Sapindaceae family of plants, which is known for its diverse range of flowering trees. The origins of Aesculus x carnea ‘Briotii’ can be traced back to Germany in the 19th century. It is named after Pierre Louis Briot (1804-1888), a renowned French horticulturist.

Description of Aesculus x carnea ‘Briotii’:
Aesculus x carnea ‘Briotii’ is a medium-sized deciduous tree that can reach a height of approximately 6 meters or 20 feet. Its palmate compound leaves are a lush dark green, consisting of 5 to 7 oblong leaflets that possess a distinctive doubly-toothed edge. These elegantly shaped leaves enhance the tree’s visual appeal, particularly during the growing season.
One of the most enchanting features of Aesculus x carnea ‘Briotii’ is its eye-catching flowers. Displayed in erect panicles that can reach up to 20 centimeters or 8 inches in length, these pink blossoms create a stunning spectacle. The tree bursts into bloom in late spring, typically in May, marking the arrival of the flowering season with a profusion of vibrant pink hues. After the flowering period, Aesculus x carnea ‘Briotii’ produces capsules that contain 2 to 3 nuts. It is important to note that these nuts are toxic and should not be consumed.
Cultivation of Aesculus x carnea ‘Briotii’:
Sunlight: Aesculus x carnea ‘Briotii’ thrives when grown in areas that receive full sun or partial shade. Providing the tree with an optimal balance of sunlight and shade throughout the day is crucial to its overall health and vigor.
Watering: Regular watering, especially during the first year after planting, is essential for the establishment and growth of Aesculus x carnea ‘Briotii.’ Deep watering ensures that the moisture reaches the roots, promoting healthy development.
