American arborvitae
Thuja occidentalis 'Degroot's Spire'
American arborvitae (Thuja occidentalis 'Degroot's Spire') is an evergreen conifer that is popular for its distinctive beauty. Perfect for providing year-round greenery, it grows tall but not wide, making it perfect for windscreens and privacy barriers. Its green foliage turns yellowish-bronze during winter months. This hardy species is highly tolerant of drought, salt, and can even withstand strong wind gusts. 'Degroot's Spire' is a popular columnar variety that is an ideal choice for smaller, narrow spaces. Its symmetrical shape stays true to form and requires little to no pruning.
