Oak, Columnar English

The tree has a tight, upright habit with a columnar shape and produces small, yellowish-green flowers in the spring that are followed by acorns in the fall. Its foliage is a dark, green color with lobed leaves that turn a yellow or brown color in the fall. The bark of the Columnar English oak is gray-brown and develops ridges and furrows with age.

Columnar English oak is a popular tree for urban landscapes and smaller gardens due to its narrow, upright growth habit. It is also known for its hardiness and adaptability to a range of soil types and environmental conditions.
