Plant grows from 20 to 50 cm with several stout, erect or somewhat curving stems. Flowers range from 17 to 23 mm and are various shades of violet and pink. Guidelines may or may not be present. Leaves are gray-green and waxy. Selected from a narrow leaf penstemon collection from the San Juan basin of New Mexico. The collection was evaluated for survival under agronomic conditions. After 5 years of establishment in fields at the New Mexico Plant Materials Center, plants were selected for hardiness. Seed from hardy plants were collected and used to establish the San Juan germplasm field of narrow leaf penstemon. Potential uses include erosion control, wildlife food/cover, restoration of disturbed sites, increasing plant diversity of rangelands, and for low water use beautification of urban and rural landscapes. Found from western Kansas to southern Utah, southward into New Mexico and northern Arizona. It commonly inhabits sandy places on plains, hills, and dunes at 1520 to 2128 meters. Requires a minimum of 160 growing season days in late winter-early spring, a cold hardiness zone of 3 to 7, and precipitation between 13 and 25 cm. | 1613057 | PI 617096 |

Plant grows from 20 to 50 cm with several stout, erect or somewhat curving stems. Flowers range from 17 to 23 mm and are various shades of violet and pink. Guidelines may or may not be present. Leaves are gray-green and waxy. Selected from a narrow leaf penstemon collection from the San Juan basin of New Mexico. The collection was evaluated for survival under agronomic conditions. After 5 years of establishment in fields at the New Mexico Plant Materials Center, plants were selected for hardiness. Seed from hardy plants were collected and used to establish the San Juan germplasm field of narrow leaf penstemon. Potential uses include erosion control, wildlife food/cover, restoration of disturbed sites, increasing plant diversity of rangelands, and for low water use beautification of urban and rural landscapes. Found from western Kansas to southern Utah, southward into New Mexico and northern Arizona. It commonly inhabits sandy places on plains, hills, and dunes at 1520 to 2128 meters. Requires a minimum of 160 growing season days in late winter-early spring, a cold hardiness zone of 3 to 7, and precipitation between 13 and 25 cm. | 1946792 | OPGC 4243 |
