Fast Facts:
The fruit of horse chestnuts are called “conkers” and the seeds are very toxic. Conkers can be used to repel moths and have also been used to treat spider veins.
The flowers are not wind pollinated, but instead rely on insects and other pollinator species for reproduction.
During both World Wars, conkers were utilized due to its source of acetone, which is used to make cordite for military armaments.
Horse chestnuts are often cultivated and planted in urban areas as street trees. Here in Reno, they have been planted in Idlewild Park.
