Crimson Wings Rumex Venosus
The name Crimson Wings is applied to this dock on account of the brilliant rose-colored calyx. The latter becomes enormously enlarged as the flower goes to seed and thus forms a device for the carriage of the seed by the wind. The low plants grow in sandy soil at 4000-8000 ft. and bloom in spring and early summer. This species has no value except possibly as an ornamental, but other species of the genus are cultivated for salad, and several of the wild species furnish excellent “greens.”
