Douglas milkvetch is really a nice little plant that causes no problems that I've seen while creating a visually delightful addition to the garden. This little locoweed grows on the Santa Margarita nursery site and up around Big Bear. At 7000 foot the plants are small little things with huge pods.
Munz says Douglas Milkvetch, or locoweed grows in "Dry fields, grassy and brushy hillsides and rolling plains, from the valley floor upward into the pine-belt, 180-6800 ft., V. grassland, foothill woodland, yellow pine forest, rarely Joshua tee woodland, central Great Valley, Yolo to Merced cos., s. in the inner Coast Ranges from San Benito Co. to the head of San Joaquin Valley, the San Gabriel and San Bernardino mts., extending to the desert-edge near Cajon and Walker passes."
