Silky lupine grows in northern areas from Washington and Oregon east to South Dakota. Tailcup lupine is found in Oregon, California, Idaho, Utah, Montana, and Wyoming. Velvet lupine is found in an intermountain region from Oregon to Wyoming. Silvery lupine occurs from North Dakota and Idaho south to Arizona and New Mexico.
These herbaceous perennials can be between 12 inches and 5 feet tall, although some species grow up to 10 feet, and are notable for their bright flower spikes. They germinate reluctantly, making it important to plant lupines at the right time of year.
