Variegated Red Horsechestnut

Aureomarginata is a variegated red horse chestnut with palmate leaves edged in yellow and clusters of light pink-red flowers. It develops into a large deciduous tree, so allow room for its eventual canopy. ## Form and Seasonal Interest This selection of *Aesculus × carnea* pairs a medium-green leaf with a yellow margin; pink-red flower panicles add spring color. [Dancing Oaks Nursery](https://dancingoaks.com/products/aesculus-x-carnea-aureomarginata) reports mature dimensions up to 40 ft tall and wide, with plants around 15 ft after ten years. [Mr. Maple's cultivar listing](https://mrmaple.com/products/buy-aesculus-x-carnea-aureomarginata-variegated-red-horse-chestnut) describes the yellow-edged foliage and early-spring blooms. Those growth estimates are age- and site-dependent, and should be treated as planning guidance rather than a fixed mature size. ## Siting Grow in full sun or partial shade in well-drained soil. The exact-cultivar nursery profile also reports clay tolerance. The RHS profile for the red horse chestnut species identifies it as a deciduous tree and advises moist but well-drained soil; NC State Extension notes that horse-chestnut seeds and other plant parts are poisonous if eaten. Keep the large, inedible seeds away from children and pets. ## Maintenance Water during establishment and prolonged dry weather. Remove damaged or crossing branches as needed, and clear fallen seed capsules from paths or play areas.
