Happy #ArborDay! 🌲🌳🌴 @smithsoniangardens' tree collection has 10 of the 600-some species of oak, and you can find them in every one of our gardens. (This is Quercus hemisphaerica, or Darlington oak.) Our oaks provide a habitat to 373 species of butterflies and moths, and oak acorns are a vital food source for local mammals.
