Our decade old specimen of dwarf upright European hornbeam (Carpinus betulus ‘Columnaris Nana’) has reached a staggering 3.5′ in height. This dwarf, narrow selection is perfect for a small patio. It should eventually reach 6-7′ in height–enough to provide shade for small insects and garden gnomes that live near the trunk.
We have been very impressed with the very narrow selection of our East Coast native arborviatae, Thuja occidentalis ‘Brobeck’s Tower’. This has been in the garden now for 4 years, and is 6′ in height and just over 1′ in width. This seedling selection was made by Sweeden’s Anders Brobeck, where the same plant takes 20 years to reach this height, due to a lack of summer heat.
People, especially male landscape architects love to use Italian Cypress in their garden designs. Few evergreen plants have the insanely narrow, upright, bean-pole shape, without benefit of pruning. We can now add a North American native counterpart to that short list, which will be welcomed since Cupressus sempervirens (Italian Cypress) doesn’t thrive in our climate.
The photo below is Juniperus virginiana ‘Silver Spear’, a Mark Weathington selection of our native red cedar. Our original plant pictured below is now 8 years old and has never been sheared. Winter hardiness should be Zone 4-9.
