Macnab's Cypress
Hesperocyparis macnabiana
  
About Macnab's Cypress (Hesperocyparis macnabiana) Nurseries Show All Photos Cupressus macnabiana (MacNab Cypress or Shasta Cypress) is a species of cypress endemic to northern California. It is one of the most widely distributed of all the native California cypresses, found growing in chaparral, oak woodlands and coniferous woodlands along the inner northern Coast Ranges and the foothills of the northern Sierra Nevada. It is an evergreen shrub or small tree, 3-12 meter (rarely to 17 meter) tall, with a spreading crown that is often broader than it is tall. The foliage is produced in dense, short flat sprays (unlike most other California cypresses, which do not have flattened sprays), bright waxy pale gray-green in color, with a strong spicy-resinous scent. The leaves are scale-like, 1-2 millimeter long with an acute tip, and a conspicuous white resin gland on the center of the leaf. Young seedlings produce needle-like leaves up to 10 millimeter long in their first year.
