My husband & I went to the Arnold Arboretum in Boston to take a gander at the trees & shrubs just coming out of dormancy. The Arboretum is well known for its lilac display, but the lilacs are not blooming as yet. ACER GRISEUM. Really cool bark, huh? GOLDEN HOPS. It grows as a vine. NAMELESS TREE. Very cool, isn't it? Looks like Cousin It, doesn't it?
