Report an issue with this species

The Red Horsechestnut is a hybrid ornamental tree known for its showy, dark red flowers in spring, followed by poisonous, prickly fruits. It thrives in moist, well-drained soils and can tolerate some drought, but is susceptible to leaf scorch in hot, dry conditions. Squirrels are attracted to its fruits.
