Hedýsarum pabulàre
Pink
Spring, summer
Utah
A very handsome and decorative plant, with large brilliant flower-clusters, contrasting well with the foliage and making spots of vivid color on dry plains and hillsides. It has many stems, springing from a rootstock, which are from eight to fifteen inches long, yellowish-green, ridged, and covered with inconspicuous down, the leaflets are light bluish-green, thickish, nine to seventeen in number, and the bracts are thin and dry. The flowers are about three-quarters of an inch long, with a pinkish-green and downy calyx, and the corolla all bright deep pink, fading to blue, with a veined standard. The pod has from three to five divisions. This flourishes at rather high altitudes, up to seven thousand feet, and is conspicuously beautiful near the entrance to Ogden Canyon in Utah.
There are a great many kinds of Trifolium, or Clover, difficult to distinguish; low herbs; leaves usually with three leaflets, usually toothed; stipules adhering to the leaf-stalks; flowers in heads or spikes; stamens usually in two sets of nine and one; pods small, mostly enclosed in the calyx, usually with one to six seeds.

It is smooth all over and grows from eight inches to two feet high, with spreading stems and narrow leaflets, which are toothless, or have teeth and bristles on the edges.
