Delphinium viridescens is a species of flowering plant in the buttercup family known by the common name Wenatchee larkspur. It is endemic to central Washington state in the United States, where it occurs in the Wenatchee Mountains in Chelan and Kittitas Counties. This plant grows in moist to wet spots in coniferous forest and riparian habitat types. The soils are not well drained and the substrate may be saturated or even covered in water as late as early summer. The species is adapted to fire-prone habitat and can resprout from its rhizome if its aboveground parts are burned away.
