There are several minor tree species or shrub species that reproduce the elegance ofhorse chestnutin smaller spaces.

The classichorse chestnut, Aesculus hippocastanum, for about 15 years, has been attacked by a small miner moth which causes a tragic defoliation. This moth, Cameraria ohridella, is the cause of the most common horse chestnut disease: in a few weeks it causes the loss of leaves.

To combat this parasite, there are no natural remedies and, at the moment, it is only possible to resort to endotherapy. Endotherapy is a rather expensive specialized technique, it consists in injecting an aqueous solution containing the active ingredient into the stem of the plant capable of eliminatingCameraria ohridella. The treatment is not without contraindications as the same active ingredient can damage other tissues of the plant and "good" insects, especially bees that feed on horse chestnut flowers.

The minor species appear to be immune to the Cameraria ohridella parasite so they can be cultivated with a light heart.

Horse chestnut seeds are rich in starch and for this reason, in ancient times, they were used for feeding horses; that's how the name was bornhippocastanuswhich means "chestnuts for horses". For the "crazy chestnuts" of the horse chestnut are they not edible?Because they are rich in saponin, a compound that makes them bitter. The seed of this plant was reduced to a paste for use as a detergent and, in folk medicine, it is still used today for its vasoconstrictive properties.
