Cupressus arizonica var. glabra 'Chaparral' is a large growing, narrowly upright, tree-form of Arizona cypress with unique, seafoam-green colored foliage. After 10 years of growth, a mature specimen will measure up to 10 feet (3 m) tall and 5 feet (1.5 m) wide, an annual growth rate of 12 inches (30 cm) or more. 'Chaparral performs best when planted in full sun in well-draining ordinary soil.
This cultivar originated as a seedling selected in the late 1980s by John Emery of Drue Wholesale Nursery, Berry, Australia.
'Chaparral' does well in the Raleigh, NC area of Zone 7b. Its spectacular cream colored outer foliage, overlaying the powdery blue-green interior, remains constant, year round. This specimen has been in my garden for four years. In that time, it's grown approximately three feet. It's sited in full sun.

I am befuddled. The original tag on a Cupressus 'Blue Ice' purchased in 2015, identifies it in this class. It is now 6-8 feet tall. It is NOT pyramidal in shape - it is a skinny, definite columnar shape. I am thinking it was mislabeled and is a Chaparral cypress - as the light blue/white coloring and slim profile suggests it.
I has been in a large pot and am wondering if that limited its width growth? Or is it just another species.
It has outgrown the 20"x20"x20" pot & am considering repotting into a larger pot. Height is not an issue in our garden, but excessive width is.
Is a wider, larger pot ill advised? Would a photo assist in correctly identifying the tree?
I planted my chaparral about a month ago. It is starting to drop needles that are yellow. Ive kept it watered. But I did not plant any fertilizer with it. What should I do? I’m thinking of pulling it up and adding fertilizer? I have Espoma holly tone..... please help :)
what you're describing sounds like classic transplant shock. Spring, as the plant is going into an active growth cycle, is actually the worst time to plant. It's also possible that you're over-watering. It would help to know where you're trying to grow your 'Chapparal'. Also, never fertilize a plant in the landscape unless a soil test indicates a deficiency.
I would just stand by at this point. You'll know by mid-summer if the plant is going to make it or not.
So the height stat for this tree is 12 inches per year. I'm assuming that depends on climate. I live in Western Washington in zone eight be in receive a lot of winter rain but summer sun and dryness. My sunniest location is only about seven hours of sun in the summer and four at best in the winter. I guess I'm trying to figure out if my tree is going to grow faster as a result of its conditions or slower than the norm.
I Tabatha, I also live in w. Washington. I also have a 'Chaparral' ... it grows pretty fast. I can't predict whether your tree will grow slower and faster, but the more shade it has, the more sparse and open the foliage will be.
