Pinus monophylla
P. monophylla (Pinyon Pine) – This native is an
extremely “sappy” tree that tolerates extreme
drought. It burns very hot. It does not tolerate
landscape irrigation.
P. jeffreyi (Jeffrey Pine) – The volatile oils in this
native tree are a fire hazard near a home.
P. nigra (Black Pine) – The black pine is one of
the most widely used landscape pines. Its dense
growth makes it another pine to keep away
from the house.

dead interior needles, this tree can ignite and
send embers flying for long distances.

tionally planted next to foundations. This plant
can reach 30 ft. in height and spread 15 ft. It
is one of the worst evergreens for having dead

hazard and should be removed within 30 ft. of
the house.
