Pine Trees That Do Well in Flagstaff

Flagstaff, Arizona, is in USDA Hardiness Zone 5 where winter temperatures can get as low as 20 degrees below zero. This gives gardeners in Flagstaff the opportunity to plant and enjoy the same members of the pine tree family as their neighbors much further north. Pine trees are tough, do not need a lot of care and stand out from all the other plants.

White Fir

White fir (Abies concolor) is also known as concolor fir. The tree grows from 50 to 75 feet tall and 20 to 30 feet wide, dense and shaped like a pyramid. The blue-tinged needles grow from 2 to 3 inches long. The pine cones grow on the top third of the tree reaching from 4 to 5 inches long. Plant white fir in full sun and a soil that is moist and well drained. Deer will make a meal out of the bark.

Engelman Spruce

Engelman spruce (Picea engelmannii), a native of Arizona, is shaped like a pyramid and grows from 40 to 50 feet tall with blue dense needles about 1 inch long. The pale-tan pine cones grow only on the ends of the branches reaching from 1 to 3 inches long and 1 inch wide. Plant Engleman spruce in full sun and well-drained organic soil.

Limber Pine

Limber pine (Pinus flexilis) grows from 30 to 50 feet tall and about half as wide. The blue-green needles are curved or twisted and grow from 2-1/2 to 3-1/2 inches long and stay on the tree for five to six years. The tree has both male and female flowers with the male flowers growing in clusters, and the female as singles or in groups of just two or three and pine cones that grow from 3 to 6 inches long.
