Duration: Perennial Nativity: Native Lifeform: Forb/Herb General: Erect or prostrate spreading herb, dusty green in color, pubescent to wooly with appressed, ascending hairs. Leaves: Ovate to elliptic with obtuse, acute or acuminate tips, margins entire, alternate, pubescent to wooly, 8-22 mm long. Flowers: White or blue with white centers, rotate (wheel-shaped) flowers with rounded, sometimes cleft petals, to 10 mm wide, filaments 2-3 times as long as the anthers, borne on slender, delicate pedicels arising from the leaf axils. Fruits: Globose, 4-valved, glabrous capsules, with 1-4 tan or brown ovoid seeds. Ecology: Found in disturbed areas and on rocky substrates; 2,500-5,500 ft (762-1676 m); flowers April-September. Distribution: s AZ, NM, sw TX, MO, AL and FL; south to Notes: Our Evolvulus species are often low-growing, have alternate, usually linear to ovate, entire leaves; blue, white or purple flowers often the shape shallow bells or funnels (salverform, rotate, funnelform) that arise from axils; and capsules. E. alsinoides is a perennial with many branching stems which can become tangled and messy, having a nest-like appearance; dense, long, silver hairs all over; stems below flowers (peduncles) which are longer than subtending leaves (shorter to absent in nuttalianus and sericeus) blue flowers 5-10 mm wide (12-22 mm in arizonicus), which are smaller than the other species in Arizona. Ethnobotany: Unknown Etymology: Evolvulus comes from the Latin evolvo, meaning to unroll, while alsinoides means resembling a species of the genus Alsine.
