Ipomopsis arizonica (Arizona ipomopsis) is a native California herb in the Polemoniaceae family, recognized by flower tube length and included reproductive parts.
Arizona ipomopsis is a California native perennial found in the eastern Desert Mountains in open, sandy to rocky canyon areas at elevations of 1,500 to 3,100 meters. Flowering from May to October, this plant produces red flowers with narrow acute lobes in clusters of 5 to 13 blooms along the upper third of its stem. Growing with erect stems that are glabrous or slightly hairy, it reaches heights supporting delicate floral displays. Its basal leaves are pinnately divided into 7 to 11 lobes, creating a finely textured foliage pattern with cauline leaves that are notably hairy. The plant's radial corolla has a distinctive red tube measuring 10 to 20 millimeters long, with lobes extending 5 to 10 millimeters.
