Duration: Perennial Nativity: Native Lifeform: Forb/Herb General: Herbaceous biennials to perennials, 35-100 cm tall, stems simple to branching at the base, stems often woody at base, herbage short glandular above, short pilose below. Leaves: Opposite, sessile, margins deeply lobed, appearing filiform, surfaces subglabrous to sparsely glandular. Flowers: Big, showy, lavender to bluish purple, corolla tube 35-50 mm long, throat 4-6 mm wide, lobes ovate to obovate, acuminate to apiculate at the tips, calyx 6-10 mm long, short-glandular pubescent, the lobes attenuate, stamens well exserted, inserted unequally on the tube, filaments unequal, elongate, stigmas slightly exserted, style short-pilose, inflorescences one-sided, with subsessile to short-pedicelled flowers on lateral branches. Fruits: Capsules 8-10 mm long. Seeds 5-9 per locule. Ecology: Found on sandy to rocky soils, in canyons and on open slopes, in desert shrublands, woodlands, and coniferous forest from 4,000-8,000 ft (1219-2438 m); flowering August-October. Distribution: Arizona, Texas, New Mexico. Notes: Look for this species under the basionym Gilia thurberi in older texts. The long-throated bluish-purple flowers with exserted stamens and deeply lobed, almost filiform leaves are good indicators for this species. This species differs from the similar I. macombii in that I. thurberi has a short-pilose style and well exserted stamens, and I. macombii has a glabrous style and not or only slightly exserted stamens. Ethnobotany: There is no use recorded for this species, but other species in this genus have uses. Synonyms: None Editor: LCrumbacher 2012 Etymology: Ipomopsis comes from the Greek ipo, "to strike," and opsis, "appearance," thus of striking appearance, while thurberi is named after Dr. George Thurber (1821-1890), called the most accomplished horticulturist in America, and botanist and quartermaster of the Mexican Boundary Survey, 1850-1854.
