About Polemonium micranthum Benth.
Polemonium micranthum Benth. is a species of flowering plant in the phlox family, commonly called annual polemonium or annual Jacob's-ladder. It is native to western North America, where its range extends from British Columbia to North Dakota to California. It also has a disjunct population in the Andes of southern Argentina and Chile. This plant grows in many types of shrubby habitat, including sagebrush scrub and foothill woodlands.
It is an annual herb with a branching or unbranched stem that can grow in a matted, spreading, or upright form. Its slender stems reach up to around 30 centimeters long, and the leafy above-ground parts of the plant are covered in short, soft hairs and stalked glands. Its leaves grow along the stem, and each leaf is divided into several small leaflets. It produces solitary flowers, which have small white or pale blue lobed corollas that are tucked within cuplike calyces made of hairy, pointed sepals.
