About

Cornus excelsa is a semi-evergreen tree native to Mexico, capable of growing up to 10 meters tall. It has a broad, spreading form and bears pointed, oval leaves that are dark green, changing to red hues in the fall. In early to mid-summer, it produces small white flowers, which are succeeded by dark blue to black berries in autumn. This species is uncommon in the UK.
