Bush lupine is a large, erect, woody-stemmed
perennial shrub up to 5' tall with green branches. The leaves
are on 4" petioles and are palmately divided into 6-9 elliptic
to oblong-oblanceolate leaflets that are slightly silky-pubescent on
both surfaces. The flowers are scattered to ± whorled on
long 8"-16" racemes, papilionaceous, petals blue to violet,
the banner glabrous and with a central yellowish spot, and the keel
ciliate on the upper edges from middle to tip. There are ten stamens
fused into a tube surrounding the pistil, with long and short anthers
alternating. The fruit is a brownish to gray pod up to 2-1/4"
long containing 6-8 seeds. Bush lupine is most often found below 1500'
in coastal sage scrub, chaparral and oak woodland from Baja to Ventura
Co., blooming from April to June. These pictures were taken in Santa
Ynez Canyon in lower Topanga State Park.
