Characteristics:
Peck's Penstemon is a small perennial wildflower with
minute flowers. It may be easily confused with its near
relatives, P. cinicola and P. procerus var. brachyanthus. It
consists of one to several stems which may arise 25 to 70
cm in height from a cluster of sterile shoots at the base.
The leaves are primarily found on the stem. They are entire
and linear to slightly elliptical in shape. The leaves are
largest on the upper stems, reduced on the lower stems.
The leaves at longest may be 5 cm in length.
The inflorescence is open, consisting of 3 to 10 many
flowered clusters which encircle the stem. The small
flowers are pale blue to lavender, and occasionally nearly
white. They are glandular and may be 6 to 10 mm long.
The tube is narrow. The staminode is expanded and lightly
bearded. The anther sacs split completely and are round in
shape at maturity.
Peck's Penstemon was named in honor of Morton E. Peck
(1871-1958) who was a well known Oregon botanist and
botanical author earlier this century.
Habitat:Peck's Penstemon is typically found in Ponderosa Pine forests in dry volcanic soil.
Range:
This rare penstemon is found along the east slope of the Cascade Mountains in Jefferson and
Deschutes counties of Oregon.
