Rhamnus frangula 'Columnaris' (CG)

This upright, narrow shrub features a columnar habit that makes it an excellent choice for small gardens or as a vertical accent in the landscape. It is hardy in USDA zones 2-7 and performs best in full sun to partial shade, tolerating a wide range of soil types, including moist, well-drained soils. Its glossy green foliage transitions to a striking yellow in the fall, providing seasonal interest. Small, inconspicuous greenish flowers bloom in late spring, which are followed by small black fruits that attract birds. This deciduous shrub has good deer resistance and typically reaches a mature height of 5-8 feet with a narrow spread of 2-3 feet. Ideal for low-maintenance landscapes, it brings vertical elegance and structural interest year-round.
