Sequoia sempervirens'Aptos Blue' is a strong and fast growing selection of Coast redwood with horizontal branching and pendant branchlets holding dark Blue-green foliage. After 10 years of growth, a mature specimen will measure 25 feet (8 m) or more in height and two-thirds as wide, an annual growth rate of 2.5 feet (75 cm) or more.
This cultivar originated as a seedling selected in the late 1970s at the Saratoga Horticultural Research Station, University of California at Davis. Many believe that 'Aptos Blue' and 'Soquel' are synonymous, although the differences in foliage color and branch structure cast doubt on this claim.

With proper care can I get 'Aptos Blue' sequoias to do well in Orange County CA?
Randy, Sequoia sempervirens is a very common street tree/yard tree in Southern California. There is even a grove at Chino State Park in Carbon Canyon (think really hot and dry location). Best to shelter it from the Santa Ana winds if possible. Also, it will need regular irrigation. Siting it in a lawn would be a boon as grass transpires more water than a pond or lake. I just planted a ‘Simpson’s Silver’ and noticed the ideal ph is 6.5, slightly acidic. Most of OC seems to be alkaline, so addressing soil and water ph would probably make a more vigorous plant.
