Last week, the National Arboretum and U.S. Department of Agriculture welcomed special guests from Ukraine for a ceremonial tree planting. The Arboretum planted a Fort McNair pink horsechestnut (Aesculus x carnea ‘Fort McNair’), which is a cross between a European hosechestnut and an American red buckeye. Horsechestnuts are an important symbol of Kyiv, Ukraine, and are found throughout the city. This tree can be found on the hillside below the Morrison Garden in the Azalea Collections, overlooking the Ellipse Meadow.
