Polemoniums abound in
the San Juans and nearby mountain ranges: Polemonium foliosissimum, growing erect to
three feet, is
common in high meadows and along streams; sprawling, low P.
pulcherrimum is very abundant in the dry shade of Spruce
forests; and the
intensely purple, but less common, P. viscosum grows to six
inches tall in very high
meadows and alone on alpine scree. But beware of beauty; most
Polemoniums exude a strong skunk odor when touched.
Because of the skunk-like smell of these plants, one might think that the name "Polemonium" referred to "pole"-cat (skunk), but the name is more probably for either the Greek Philosopher, Polemon, or from the Greek "polemos" meaning "strife": Pliny the Elder indicated that a war was fought over who actually discovered this plant! |

Polemonium
foliosissimum
variety foliosissimum (Jacob’s
Ladder) Polemoniaceae (Phlox Family) Montane, subalpine.
Meadows. Summer. Polemonium foliosissimum is easy to spot and identify because of its growth patterns: it is often in dense to loosely scattered colonies in open mountain meadows; it grows tall (commonly two to three feet) in an open, airy manner; and its leaves are finely cut. Its abundance of softly lavender/blue/purple flowers are borne in numerous, showy clusters. Altogether, Polemonium foliosissimum is a softly appealing, lovely plant and one of our favorites. Charles Parry first found this plant for science in Colorado and it was named by Asa Gray in 1878. "Foliosissimum" is Greek for "very leafy". (More biographical information.) |
