The story
Gambel oak covers the foothills of the southern Rockies in thickets, sprouting back from the root after every fire. Its acorns are sweeter than most and were eaten by Ute, Navajo and Pueblo peoples with little leaching.
Planting
Full sun and dry, lean, well-drained soil. It is at home on slopes where little else will grow.
Growing
Water only to establish. Thin the suckers if you want a small tree and not a grove.
Harvest and use
Cover and acorns for turkeys, deer, bears and jays; gold-to-rust fall color; and a windbreak that asks for nothing.
What to watch for
It spreads by root into thickets. Keep it back from buildings in wildfire country.
