and - bark that is gray and smooth, cracking into squares with age.
Abies religiosa
Sacred Fir
Pinaceae
Look For:
- an evergreen conifer with whorled branches,
- flattened needles that are about 3cm long with 2 white bands underneath,

Blue Atlas Cedar
Pinaceae
Look For:
- A monoecious, evergreen conifer,
- blue-green needles that are densely arranged on short “spurs” off the main branches,
and - upright seed cones that fall apart in whorls leaving a persistent central rachis.
Cedrus deodara
Deodar Cedar
Pinaceae
Look For:
- A large, attractive, evergreen tree.
- Needles are 1.5 inches long and green to gray-green.
