Dwarf goldenrod as seen amongst granitic boulders atop the Lakes Lookout, Wallowa-Whitman National Forest..........July 25, 2013.
Characteristics:
Northern goldenrod is a fairly attractive rock garden plant
with one to several erect to spreading stems from 5-50 cm high. The leaves
are oblanceolate or spatulate with acute to obtuse tips. The margins are
entire to minutely toothed towards the tips. The upper and lower leaf surfaces
are glabrous with the margins ciliate (at least on the petioles). The basal
leaves are petiolate and 2-10 cm long and 5-18 mm wide. The stem leaves
are loosely arranged, alternate, and can remain fairly large to mid stem
before becoming reduced in size. The stem leaves are also sessile or partly
clasping.
The inflorescence consists of a few heads in a dense terminal
cluster, or more loosely arranged with a terminal cluster and several small
clusters of flower heads offset below and to the side of the terminal cluster.
The involucre is 4-7 mm high with linear or lance-linear bracts having acute
to obtuse tips. There are 25-60 flowers to a head with a central disk surrounded
by 10-20 yellowish rays, each 2-5.5 mm long.
Habitat:
Northern goldenrod is found on gravelly to rocky open slopes
in the mountains and subalpine meadows from 1600m-4500m in elevation.
Range:
Northern goldenrod may be
found from Alaska and eastern Siberia south through the mountains to California,
Arizona and New Mexico. It is found eastward to Labrador, Newfoundland and
Quebec.
