There are certain trees that consistently remain my favorites. When I think about their common characteristics, one thing stands out: the bark.
Interesting bark is always there, whether the tree is leafing out, blooming or showing dramatic fall color. Bark remains constant whether the tree is good, bad, pretty or ugly.
Bark has become one of those things we look to when deciding on what to plant.
But have you ever thought about the function of bark? What purpose does it serve, and how important is it to the health of the tree?
