Description and General Information:
Penstemon pinifolius is native to upland, rocky areas of Arizona and New Mexico. Plants form a low shrub with narrow, needle-like foliage. Plants can reach 20-30 cm tall with a spread of 45 cm. Racemes of narrow, tubular, 2-3 cm long, red to yellow flowers are produced from late spring to mid-summer. Flowers are covered in glandular hairs. This species is typically pollinated by hummingbirds but is also a popular nectaring plant for butterflies.
Blooming season:
Late spring in southern areas to as late as late July in the north.
Cultivation:
Like most Penstemon, this species requires full sun and well-drained soil. This is especially important in winter. Once established, it is very drought-tolerant. The species is rated hardy to zone 4 but in cold areas, benefits from being planted in a sheltered location.
Propagation:
This species may be propagated from seed or cuttings. Seeds may be directly sown at 20 C and should germinate in a few weeks. Cuttings of non-flowering shoots may be taken in mid-summer.
