SHEER BEAUTIES

Homeowners often express a desire to include plants with winter interest in their landscapes.

These trees have excellent form and beautiful bark, and some even provide pops of winter color with persisting fruit.

. Oak trees are renowned for their strength and longevity, but the bur oak’s charm resides in its expressive form.

Bur oaks look best in large open spaces, like meadows, where they can grow up to 80 feet tall and wide and strike their form against a bright winter sky.
