The Rocky Mountain variety of Ponderosa Pine has been infrequently planted in the Chicago, Illinois region, mostly in some regular parks or in a very few yards. It has thick, stiff needles in 2's and 3's that get to 10 inches long and hurt some when bumped into. Its oval cones are fairly large, 3 to 6 inches long, with large, sharp prickles on scales that hurt. It grows about 1.5 feet/year like many large pines in Midwestern landscapes and lives 350 to 500 years in the wild. It grows in well-drained, very acid to slightly alkaline soils. In Midwestern landscapes it gets about 40 to 60 feet high, and looks very similar to the Austrian Black Pine, but the Ponderosa has longer needles, larger cones, and some needles in 3's, though it is not as adaptable to heavy clay soils, more alkaline pH, road salt and pollution as is the European tree.
