How to grow the red horse chestnut and care tips
Chinese scientific name: Red horse chestnutLatin scientific name: Aesculus carnea 'Briotii'Also known as: Color-changing treeKingdom: PlantaeFamily: HippocastanaceaeGenus: AesculusSpecies: Red horse chestnutMedium-sized flowering and foliage ornamental tree, height 12 m. Category: Foliage trees - variegated-leaf type1. Origin and distribution
Native to the Balkan Peninsula in Europe, it has been successfully introduced and cultivated in North China2. Morphological characteristics
The crown is round, with luxuriant branches and leaves. It blooms at the end of March, with panicles, large pink flowers in great number, and the leaves turn yellow in autumn. The bark is grayish brown and flakes off in plates. The branchlets are stout, chestnut brown, smooth and hairless. There are usually 7 leaflets, obovate-oblong. The flowering period is May. The flowers are small and red. The fruit is spherical or obovate, reddish brown, and ripens from September to October. It is a very ideal street tree and landscape tree. When new leaves first emerge in spring, the leaf color is as red as blood, very brilliant. In summer, it also shows multiple colors because of the different growth of the leaves, slightly red at the top, tender green in the middle, and dark green at the bottom. In autumn, the leaf color is as yellow as gold, hence it is also called the color-changing tree. The trunk is straight and very majestic. When it blooms, red conical inflorescences cover the crown, with green trees and red adornment, very beautiful.How to grow the Lancang horse chestnut and care tips

Flowers polygamous, terminal, narrowly cylindrical.1. Morphological characteristics
Deciduous tree, bark grayish brown. Branchlets cylindrical or somewhat angular near the apex, dark purple or purple-green, slightly pubescent when young, becoming hairless with age, with pale yellow oblong-elliptic lenticels. Winter buds terminal, ovate; scales 6, imbricate, purple, hairless. Leaves palmately compound, petioles pale purple and slightly pubescent, about 15-18 cm long; leaflets 7, papery, oblong-elliptic or oblong-obovate-lanceolate, rarely nearly lanceolate, the apex suddenly acute with a tail-like tip, the base cuneate, the margin with closely appressed small crenations, the middle 3 leaflets 20-24 cm long and 7-8 cm wide, the lateral 4 leaflets 15-18 cm long and 5-6 cm wide, dark green above, hairless, light green below, yellow-brown after drying; the midrib prominent above, raised below, lateral veins 20-22 pairs, diverging from the midrib at an angle of 80 degrees, often curving inward near the margin, prominent above, slightly raised below, veinlets reticulate, petiolules purple-brown, hairless, 5.7 mm long. Inflorescence terminal, rather narrow cylindrical, 5 cm in diameter at the base, together with the pale yellow slightly pubescent peduncle up to 13 cm long with pale yellow elliptic lenticels totaling 40 cm long, the rachis densely covered with pale yellow slight pubescence, small inflorescences 2-2.5 cm long, with 5-7 flowers, nearly horizontally spreading; flowers polygamous, male and bisexual flowers on the same plant, irregular; calyx bell-shaped or tubular-bell-shaped, 5 mm long, grayish pubescent outside, with about 5 unequal lobes, obtuse-acute, about 1 mm long; petals 4, unequal, grayish pubescent outside, hairless inside, the margin ciliate, white with brown patches, the front two petals spoon-shaped oblong, narrowed at the base into a claw, 2-2 cm long and 5 mm wide, the lateral two petals oblong-obovate, base cuneate, 1.6 cm long and 6 mm wide; stamens 7, filaments linear, purple, hairless, 2.5 cm long, anthers yellow, oblong-elliptic, 1.6 mm long; disk slightly lobed, located outside the stamens; ovary of bisexual flowers unknown; pedicels 3-5 mm long, grayish pubescent. Characteristics of the capsule unknown. Flowering period May.2. Distribution range
Produced in southwestern Yunnan. Grows in thickets at an altitude of 1500 m. The type specimen was collected from Lancang.3. Species differences
This species is relatively closely related to Aesculus wangii Hu, from which it differs in that the leaflets of this species are hairless and acute at the apex. The middle leaflets are often larger than the lateral leaflets; the cymose panicle is relatively narrow and small, only 5 cm in diameter at the base. Compared with Aesculus assamica Griff., this species has shorter petioles, papery and smaller leaflets, the middle leaflets slightly larger than the lateral leaflets, and the cymose panicle relatively narrow and small, only 5 cm in diameter at the base, with small inflorescences short and sparse, only 2-2.5 cm long, and the distance between two small inflorescences about 2 cm, so it is also very easy to distinguish.
