Aesculus ×carnea – Red horsechestnut

View prices and availability
A crossing between A. hippocastanum and A. pavia. Grows slower and remains smaller than A. hippocastanum. The dense crown casts a deep shade. A mature tree can reach a height of up to 20 m and a width of 15 m. The slightly shiny, opposite leaves are more or less folded and can grow to 15 cm across. They appear early in spring and remain for a long time. The autumn colour is yellow brown. Not until a tree is 8 to 10 years old, do the conspicuously coloured flowers appear. These appear as long erect, panicles of 15 - 20 cm and are pink red. The fibrous root system consists of a main root which branches out well and goes deep into the ground. The soil must not be too dry. Intolerant to asphalt and/or hard surfaces unless the base area is large enough.
