Overview
Red Horse Chestnut (Aesculus x carnea) is a deciduous tree native to the Balkans and Central Asia, including Albania, Bulgaria, Greece, Turkey, Turkmenistan, and Yugoslavia. This tree, part of the Sapindaceae family, is known for its ornamental value and edible seed. Growing up to 25 meters tall, it thrives in moist, well-drained soils with a pH between 5.5 and 6.5, making it hardy in zones 5-7. The Red Horse Chestnut features a light, airy growth habit and produces white flowers, blooming in May. Its seeds can be eaten after proper preparation, typically boiled or roasted to remove toxic compounds, and can also be ground into flour for baking. While the tree is not particularly drought-resistant, it can tolerate a range of soil types, including light (sandy), medium, and heavy (clay) soils. For optimal growth, it requires full sun to partial shade, with a light tolerance rating of 7/10, indicating it can handle some direct sunlight.
