Penstemon angustifolius (Penstemon) Semi-desert. Openings, shrublands. Spring. Penstemon angustifolius grows from four to twenty inches tall. The plants shown on this page may even exceed twenty inches as they respond to a winter of very slow snow melt which kept the upper layers of soil in perfect moisture for abundant wildflower growth. Basal leaves of Penstemon angustifolius are absent or few and stem leaves are narrow and without hairs. Leaves are a distinctive light green with a prominent mid-vein. It is very common for the growing tips of Penstemons to arch and gradually grow erect as the flower stem elongates, but this arching is pronounced in Penstemon angustifolius. Penstemon angustifolius was named by Frederick Pursh in 1814 from a specimen collected by Bradbury near the Minataree Village. "Angustifolius" means "narrow leaves". |
