Fun Facts

🌱 The common name 'Incense Cedar' refers to the warm, pleasant resinous scent released when foliage is crushed, not actual incense production.
🌱 This tree is native to mountainous regions of California and Oregon, where it grows in mixed conifer forests at elevations of 1,000-8,000 feet.
🌱 The 'Compact' cultivar was selected for urban and small-garden use, as the species plant can reach 100+ feet tall in its native habitat.
