The photo above shows velvet lupine as seen on grassy slopes above the farm buildings in Columbia Hills State Park in the Columbia River Gorge..........June 8, 2008. Velvet lupine has a long, very tightly flowered raceme with flowers from 8-12 mm long.
The photo at right of shows a close-up of the flower of velvet
lupine as seen on grassy slopes above the farm buildings in Columbia Hills State Park in the Columbia River Gorge...........June 8, 2008. Note that the upper banner is bent closely towards the lateral wings and is much shorter than the wings and keel.
Characteristics:
Velvet lupine is an attractive perennial wildflower recognized by its silvery
foliage and elongated, tightly flowered racemes. Plants typically have one to
several simple to freely branched stems which arise 30-70 cm high. The leaves
and stems are typically densely covered with a mixture of both short and long,
straight hairs that may be both spreading and appressed or occasionally both
appressed. The hairs typically are grayish or rust-colored. The leaves are generally
found on the stems, with the petioles 1-4 times longer than the blades. The
7-10 leaflets are 3-5 cm long with oblanceolate to narrowly oblong blades. Both
surfaces of the leaflets are about equally covered with silvery-gray hairs.
The racemes are long and narrow and are generally closely flowered. The pedicels
measure 1-3 mm long and are subtended by white-haired bracts about equally long.
The calyx likewise is densely haired with the upper lip cleft. The upper base
of the calyx is not spurred but may be somewhat swollen. The corolla is light
blue, pink or white in color and measures 12-14 mm long. The banner is shorter
than the wings and is only slightly reflexed. The back of the banner is densely
haired over much of its surface with the hairs extending past the calyx lobes
to the upper third or sometimes to the tip of the banner. The wings are glabrous
or perhaps lightly haired along the margins near the basal claw. The fruits
measure 1.5 - 3 cm long and 7-8 mm wide and are covered with shaggy, rusty hairs.
Former Subspecies of Velvet Lupine:
subspecies leucophyllus (formerly variety leucophyllus
) - Flowers larger, measuring 8-10 mm long. The pressed racemes are generally
much wider than 2 cm. The leaflets are typically greater than 7 mm wide with
loose, spreading, long hairs. Found east of the Cascade Mts. from central and
eastern Washington and Oregon eastward to Montana, northwestern Wyoming, Idaho
and western Nevada.
subspecies erectus (formerly variety tenuispicus)
- Flowers smaller, measuring 7-8 mm long. Pressed racemes narrower, generally
less than 2 cm wide. The leaflets measure less than 7 mm wide with short, appressed
hairs. Found from Lincoln County in Washington south to central and southeastern
Oregon and eastward to west-central and southwestern Idaho.
Habitat:
Velvet lupine may be found on dry, open rangeland or grasslands
from the lowlands and foothills to moderate elevations in the mountains.
Range:
Velvet lupine may be found east of the Cascade Mts. from central
and eastern Washington and Oregon eastward to Montana, northwestern Wyoming,
Idaho and western Nevada.
In the Columbia River Gorge it may be found between the elevations
of 100'-3000' from about the Klickitat River and Rowena in the west and eastward
towards Roosevelt, WA and Arlington, OR.
The photo at right of shows a close-up of the keel of the flower of velvet lupine as seen on grassy slopes above the farm buildings in Columbia Hills State Park in the Columbia River Gorge........June 8, 2008. The keel of velvet lupine is turned upwards and longer and more narrow than that of the similar silky lupine (Lupinus sericeus) which generally also has larger flowers.

The two photos above show the upper stem leaves and elongated racemes of a light-pink variety of velvetlupin as seen on grassy slopes above the farm buildings in Columbia Hills State Park in the Columbia River Gorge.........June 8, 2008. Much darker pink- or velvet-flowered forms of velvet lupine can be found about 35 miles north around Glenwood, WA.

The photos above show a white-flowered form of velvet lupine as well as close-up of the mass of whitish hairs of the dorsal leaflet (middle) and ventral leaflet (right) surfaces. The leavlets appear much grayer than any other species of lupine (except the hybrid lupine (L. leucophyllus X sericeus) that is found in the Columbia River Gorge. Photographed on grassy slopes above the farm buildings in Columbia Hills State Park in the Columbia River Gorge.........June 8, 2008.

Two views of late-blooming velvet lupines (one of hundreds) blooming on grassy slopes to the northeast of the Crawford Oaks trailhead, near the viewpoint on the Vista Trail, Columbia Hills Historical State Park..........October 21, 2016 at left and November 2, 2022 at right. There's a possibility these could be hybrid plants (Lupinus leucophyllus x Lupinus sericeus).
