Briotii Red Horse Chestnut

‘Briotii’ red horse chestnut is a deciduous hybrid tree with a rounded crown, dark green palmate leaves, and showy upright clusters of rosy-red flowers in spring. Its bold bloom and shade canopy suit large lawns, parks, and spacious streetside plantings; allow room for a mature tree and its seasonal leaf litter. [UF/IFAS Extension](https://ask.ifas.ufl.edu/publication/ST066) describes the cultivar’s red flowers and dense shade canopy. ## Garden Use and Appearance This cultivar is selected for its richer red flower color compared with the hybrid species. The flowers appear in upright panicles at branch tips, and the tree develops from a young pyramidal outline toward a dense, rounded canopy. UF/IFAS reports that the cultivar produces few seedpods compared with the original hybrid, though leaves and flowers can still create seasonal litter. ## Growing Conditions Plant in full sun or light shade in moist, well-drained soil. It tolerates a range of soil textures, including sand, loam, and clay. UF/IFAS gives mature height and spread of roughly 35–50 ft; [Oregon State University](https://landscapeplants.oregonstate.edu/plants/aesculus-carnea) describes the hybrid at 35–50 ft and notes that ‘Briotii’ is the rosy-crimson-flowered selection. Its large eventual size makes it unsuitable for small gardens. The tree is deciduous and may be susceptible to horse-chestnut pests and leaf diseases. ## Maintenance Allow the crown to develop with little pruning; UF/IFAS advises retaining lower branches to shade the trunk and avoiding abrupt over-pruning. Remove crossing or damaged branches when necessary, and account for fallen leaves and flowers near paving.
