I’ve always loved the smell of a freshly mowed lawn. Little did I know that this smell is produced by the blades of grass signaling distress from being injured. Research has shown that plants emit volatile organic compounds (VOCs) into the atmosphere upon mechanical damages or insect attacks. Undamaged neighboring plants sense the released VOCs as danger cues to activate defense responses against upcoming threats.

Utah Juniper All photos by Charlotte Coles |
The Utah Juniper, Juniperus osteosperma, is one of nature's caretakers. Utah Juniper is a multi-trunked tree or shrub. Roots are vast and shallow growing in gravelly loam or clay alkaline soil (pH 7.4-8.0). The Utah Juniper grows 0.5 inch per year and may live up to 600 years. They are best suited for elevations of 3000-8000 feet. This monoecious tree or shrub is able to reproduce in distant areas by wind or animals. Each berry contains 1-2 seeds and the staminate are small soft cones.
