“A society grows great when old men plant trees whose shade they know they shall never sit in.” -Greek Proverb

 

Two of my favorite shade trees are real beauties: Horse Chestnut and Copper Beech. Both trees are large, making a commanding presence in a landscape. You will need a fairly open spot not too close to the house to give each plenty of room. Planted on the south-west side of a home will provide cooling shade during the summer. Both are deciduous, shedding their leaves for the winter, allowing the sunlight to warm the house in the winter.

Horse Chestnut, (Aesculus hippocastanum), is a stately 50 to 75 feet tall and 40 to 70 feet wide at maturity. The large, palmate leaves have an opposite leaf arrangement, and are a pretty dark green. Soon after the leaves emerge the tree produces large, white panicles around mid-May. Panicles are made up of individual white, perfect flowers with a yellow blotch at the base. This yellow blotch changes to a pinky-red as the flower ages. The flowers are very showy, and I think, the best features of a magnificent tree. And the bees love it.

Horse chestnut is not a true chestnut as it is in a different genus. The nuts of Horse chestnuts are not edible due to their toxic levels of glycoside and saponin. The nuts are enclosed in a green, smoothed shell with some pointed warts. The American and Chinese chestnuts have spine covered shells. Nuts left on the ground through the will break dormancy in spring and start to grow mid-April. Dig the baby trees to move them where you would like them to grow.

Copper Beech trees are not really a copper color. More of a mahogany, but that name was already taken! Whatever you call it, it is strikingly gorgeous. The Latin name is Fagus sylvatica ‘Purpurea’ group. There are quite a few named varieties of with the different shades of purple leaves. Popular ones are ‘cuprea’, ‘Brocklesby’ and Purpea Nana’. ‘Purpurea Pendula’ is a weeping cooper beech.

Copper Beech Flowers

Size varies with the many varieties. Some can reach 60 feet tall and 45 in width. Overall shape is an oval to more rounded with age. Flowers are small, not showy and a yellowy green in color. The male flowers hang down while the female flowers are held close to the twig. Flowers are wind pollinated. If female flowers do become fertilized, a spiny husk covering a triangular nut develops. Nuts are edible, but small. It will take ten years for trees to reach maturity before flower and nut production begins lightly and 30 years for a full harvest. It is best to purchase a balled and burlapped or potted tree to make sure the leaf color is to your liking. Seedlings can vary widely in their coloring.
