The Pinyon Pine
When Spanish explorers reached the southern Rockies, they were greeted by a familiar sight. Large stands of short, bushy evergreen trees reminded them of the Stone Pines native to their homeland, so they called them by the same name—pino piñonero—a name they still go by today, albeit in a shortened form. And like its European cousin, the piñon, or pinyon, pine had been around for centuries, providing an important source of nutrition to ancient hunter-gatherer populations.
Plan Ahead for Spring Planting
Banish your winter blues by thinking ahead to spring. Avid gardeners know that winter is the best time to plan for the warm weather to come and get a head start on plentiful crops during Colorado’s short growing season. It’s also a great time to reassess your landscape plan.
The Chinkapin Oak
If you’re looking for a shade tree that a Denver city forester once described as being tough as a junkyard dog, take a look at the chinkapin oak. Sometimes spelled chinquapin, it’s a stately medium-size tree with a rounded canopy that’s native to the central midwestern US as far west as central Kansas and south into northeastern Mexico.
