Mostly sunny, moderately vegetated opening to primary City Creek valley. Growing in lightly disturbed soil about 5 meters from trail and 15 meters from creek with balsamroot, hounds tongue, snowberry, roses, russian olive, and other deciduous shrubs and trees. Berries of all hawthorns are edible, but are not very sweet and tend to be dry and mealy. The thorns of these plants can be used as fine points in tool making. In several randomized, double-blind, placebo controlled studies hawthorn extract has been shown to increase exercise tolerance, beneficially decrease the pressure-heart rate product, and reduce fatigue and shortness of breath in people with congestive heart failure. These properties are thought to be related to the plant's high flavonoid content. Possible side effects of consumption include vertigo, migraines, palpitations, gastrointestinal distress, and erythematous rash. However, reactions are unlikely and rarely serious. Phenology: Flowers.
