Characteristics:

Payette penstemon is a perennial wildflower with one to several stems which rise in a tight cluster to 70 cm in height. The basal leaves are large, measuring up to 18 cm in length. They are long and slenderly petioled. The shape of the blades is ovate to elliptical. The stem leaves are smaller (4-8 cm), sessile and lanceolate. The margins of all the leaves are entire.

The inflorescence is a fairly dense panicle, consisting of three to ten verticillasters. Each verticillaster is two-to four-flowered. The corolla is blue to purple and is up to 2.8 cm in length. The tube flares to a broad throat and is glabrous throughout, as are the lobes. The corolla is definitely two-lipped with the lower lip longer than the upper. The calyx consists of 5 lanceolate sepals with acuminate tips. The sepals measure from 4.5-8 mm long. The anthers split along the outer 4/5 of their edge, the sacs spreading opposite of each other. The staminode is glabrous or occasionally lightly yellow-bearded and slightly expanded at the tip.


Habitat:

Payette penstemon is found in talus or open slopes to forests and brushy areas from the foothills to subalpine elevations in the mountains


Range:

Payette penstemon is found from the Wallowa Mts. of northeastern Oregon eastward across central Idaho to just east of the border with Montana.
