Red Horse Chestnut Aesculus × neglecta 'Erythroblastos'
ABOUT
Commonly known as the autumn splendor horse chestnut, this ornamental plant is recognized for its distinctive foliage that undergoes a captivating color transformation throughout the seasons. During the spring, the new leaves emerge with a pronounced pink to salmon flush, setting it apart from other garden plants. As the leaves mature, they transition into a striking lime green or yellowish hue, creating a vibrant contrast against the backdrop of the customary green landscape. The leaves are composed of five to seven leaflets that radiate from a central point, resembling an open hand, which is typical of the horse chestnut family. This palmate arrangement contributes to a lush, full appearance that adds texture and visual interest to any garden setting. In the course of the year, the plant produces upright clusters of flowers. These blossoms can be quite showy, adding an additional layer of ornamental value. The flowers' hues typically range from creamy white to pale pink, which further complement the changing foliage. After the flowering season, non-edible, capsule-like fruit encasing large, shiny seeds may develop. These seeds are often referred to as "conkers" and can be an identifying feature of the plant. Overall, the autumn splendor horse chestnut presents a harmonious blend of colors, from its unique foliage to its graceful flowers, providing a dynamic and changing display that captivates the attention of gardeners and onlookers alike. Its capacity to shift hues with the seasons makes it a favored choice among plants for landscaping that can offer year-round visual interest, barring the details of its size or growth habit.

WaterThe Red Buckeye, commonly known as Aesculus × neglecta 'Erythroblastos', should be watered deeply once a week, providing about 1 to 1.5 gallons of water each time, depending on the weather conditions and soil drainage. During hot, dry spells, watering frequency may need to increase to twice a week. Allow the top inch of soil to dry out before watering again to prevent overwatering. It is important not to let the soil become waterlogged, as this can lead to root rot. Always water the base of the plant, avoiding wetting the foliage, to minimize the risk of fungal diseases.
LightThe Red Buckeye prefers to be placed in a spot with full sun to partial shade for optimal growth. Too much shade may lead to fewer flowers and a leggy growth habit, while too much direct sun can scorch the leaves, especially in hotter climates. An ideal location offers morning sunlight with some afternoon shade, especially in areas with intense midday sun.
TemperatureThe Red Buckeye can tolerate a range of temperatures but thrives best when the temperature is between 60°F and 80°F. It is hardy and can survive minimum winter temperatures down to about -20°F. During hot summer weather, the plant benefits from extra watering if temperatures consistently rise above 90°F.
PruningThe Red Buckeye requires little pruning other than to remove any damaged or diseased wood and to maintain its shape. Pruning is best done in the late winter or early spring before new growth begins. Occasional thinning of the branches may be necessary to allow light and air to penetrate the canopy, encouraging a healthy growth habit.
CleaningAs needed
SoilThe Red Horse Chestnut requires well-draining, fertile soil with a pH of 6.0 to 7.5. A good mix would include loamy soil, compost, and a small amount of sand to improve drainage. Regular mulching can also help to maintain soil moisture and health.
RepottingRed Horse Chestnut trees do not typically undergo repotting as they are large trees best suited for outdoor planting. Instead, they may require occasional transplanting when they outgrow their location, generally every few years during their juvenile stage or as needed.
Humidity & MistingThe Red Horse Chestnut thrives in average outdoor humidity levels. While specific humidity requirements are not critical for this tree, it benefits from the natural variations of outdoor conditions without needing special attention to humidity.

Life cycleThe Red Horse Chestnut 'Erythroblastos', Aesculus × neglecta 'Erythroblastos', begins its life cycle as a seed, typically a shiny, dark brown nut encased in a prickly husk which falls to the ground in autumn. Upon germination, which may require a period of cold stratification, the seedling emerges with the first pair of leaves and begins to establish a root system. As the sapling grows, it develops a distinctive pink-tinged foliage in spring, which matures to a pale yellow-green color throughout the growing season. The plant reaches maturity in several years, at which point it produces its characteristic panicles of red or pink flowers, usually around late spring to early summer. After pollination, often by bees, the flowers develop into the species’ fruit, the spiny husks containing the seeds. The cycle is completed as the seeds drop in the autumn and potentially germinate to produce new saplings, continuing the species' life cycle.
PropogationPropogation time
Early spring
Aesculus × neglecta 'Erythroblastos', commonly known as the Red Horse Chestnut, is typically propagated by grafting, which is the most popular method used for this plant. The best time to graft Red Horse Chestnuts is in late winter or early spring before new growth begins. To propagate by grafting, a scion, which is a short length of stem with several buds, is taken from a healthy, disease-free parent plant. This scion is then joined to a rootstock, which is often seed-grown Horse Chestnut or a closely related species, by making matching cuts on both the scion and the rootstock and binding them together until they fuse. The grafting site should be kept moist and wrapped to encourage successful union, with grafting tape or similar materials. After the graft has taken, usually evident by the growth of new shoots from the scion, the tape can be removed, and the new plant can continue growing with the combined characteristics of the scion and rootstock.
