Incense Cedars are native throughout California and can be found in warmer zones than the listed zone 8b. They are native in abundance to my zone 9a climate, and thrive in full sun or part shade with no summer irrigation.

Far superior in my opinion to the more common large Thujas. It is both sturdier and more graceful. An excellent hardy conifer for the South and Midwest where weather conditions can limit the number of growable conifers.

I planted a 3.5' tall specimen last summer. It is a nice texture and color. I saw some really nice ones at the Spring Grove Cemetary in Cincinnati, Ohio a few years ago. It isnt very well known in the midwest and therefore not planted here. California Incense Cedar has very interesting bark to offset the foliage. It handled our winter lows of -8F over the winter with light browning on the lower branches. I assume this is typical since many evergreens shed old leaves as new growth begins It seems to be a late starter in the spring for Growth as it is the last thing to start growing in the yard out of many different woody plants.
