Delphinium leucophaeum
Also called Light Yellow Flowered Larkspur
Delphinium leucophaeum is a rare, endangered perennial larkspur native only to the Willamette Valley of Oregon and nearby Washington. It is seldom grown in gardens, so cultivation advice here is general and mostly applies to related garden larkspurs.
Delphinium leucophaeum is an endangered species of larkspur known by the common name white rock larkspur or pale larkspur. It is endemic to the Willamette Valley of Oregon. Some consider it to be a synonym for or variety of Delphinium nuttallii.
