Looking for plants that can fit in narrow areas, while still maintaining vertical interest? Choosing tall, narrow varieties can minimize the amount of pruning and maintenance needed. Try these columnar selections:
These deciduous shrubs are tolerant of a variety of conditions. During the fall, their leaves change color and give way to spiny stems and small berries. Leaf colors differ by variety, from deep reds to chartreuse.
Example Species: Berberis thunbergii “Golden rocket” (4′ tall and 2′ wide) | Berberis thunbergii “Helmond Pillar” (4′ tall and 2′ wide)
This hardy shrub is tolerant of sun and shade, as well as cold winter temperatures. These columnar varieties are great for hedges, screening, or green fence lines.
Example Species: Buxus sempevirens “Graham Blandy” (8′ tall x 1′ wide) | Buxus “Green Mountain” (5′ tall x 3′ wide) | Buxus “Green Tower” (9′ tall x 2′ wide)
