- 🌱 The plant is incredibly hardy once established and can tolerate coastal salt spray, strong winds, and poor soil better than many ornamentals, making it popular in challenging landscape locations.
- 🌱 Its dense evergreen foliage and compact growth habit make it an excellent privacy screen or hedge; some cultivars can be trained into topiaries or formal shapes with regular pruning.
