species of plant
Polemonium pulcherrimum is a species of flowering plant in the phlox family known by several common names, including beautiful Jacob's-ladder, showy Jacob's-ladder, and skunk-leaved polemonium. It is native to western North America from Alaska and Yukon to Arizona and New Mexico, where it can be found in many types of mountain habitat, including alpine talus and rock cracks at high elevations. It is a common and widespread wildflower in several regions. It is a perennial herb producing a clump of several erect stem approaching a maximum height of 30 centimeters. The leaves are mostly basal, with smaller ones arranged along the stem. The leaves are made up of several pairs of lance-shaped to oval or round leaflets. The herbage is lightly hairy, densely glandular, sticky, and strongly scented, the odor reminiscent of skunk. The showy inflorescence is a dense elongated or headlike cluster of bell-shaped flowers each just under a centimeter wide. The flower is deep to bright or pale blue to nearly white with a yellow throat.

Why this record matters
“Polemonium pulcherrimum” is worth following because a concise public description often conceals a longer documentary argument. Here, Polemonium, pulcherrimum and species provides the most credible route into that argument.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Aug 13, 2026. The linked authority identifier is Q9061370. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1830.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
