Zelkova carpinifolia, commonly known as Caucasian zelkova, is a deciduous tree native to the Caucasus region and northern Iran. It is known for its attractive bark, which exfoliates to reveal patches of orange and brown, and its resistance to Dutch elm disease. The tree can grow up to 30 meters tall and has a broad, spreading crown.
Caucasian zelkova thrives in temperate climates with moderate temperatures. It prefers full sun to partial shade and should be watered regularly to keep the soil partially moist. The tree is relatively hardy and can tolerate a range of conditions, but it performs best with consistent care.
