Penstemon rydbergii
A widespread species native to much of the western United States, including California, growing in mountainous regions in moist meadows and along streams. Forms a low rosette of bright green leaves topped with flower stems 1 -2 foot tall. The small, lavender-purple, tubular flowers are clustered in whorls on dense spikes. The blossoms offer an excellent source of nectar and pollen to hummingbirds, bees and butterflies, as well as a larval food source for a number of butterfly species. Considered easy to grow and long lived. Plant in full sun to light shade with regular moisture. Somewhat winter deciduous. Deer resistant.
Penstemon speciosus
Found in higher elevation localities of inland Northern California, royal penstemon is a vibrantly colorful addition to the dry, full sun garden. In summer, the large, saturated blue-purple florets are held in clusters on stems rising almost 2’ tall above a low, evergreen rosette of glossy, strap-like foliage, reaching 1' - 2' wide. Attracts a multitude of pollinators. Does best with decent soil drainage, and inland sites that provide seasonality—colder winters, and hotter summers. Drought-tolerant once established.
Penstemon spectabilis
A spectacular Penstemon native to dry, gravelly slopes of southern California and northern Baja. Demanding good drainage and full sun, this perennial grows 3 ft. or more tall with striking displays of lavender-purple tubular flowers. A challenging species with a sensational floral display, but can be short lived in northern California. Performs best in hot inland gardens. Take care not to over water. Highly attractive to hummingbirds as well as bees and butterflies.
Penstemon strictus
Showy perennial, native to a number of states in the Rocky Mountains, where it grows in sage brush and coniferous forest communities. Forming clumps of neat evergreen foliage 8 - 10 inches tall by 36 inches wide. Mid to late spring brings flowering stems 2 foot or so above the foliage with deep blue-purple tubular flowers. Considered one of the easier to grow, tolerating heavier soil and moisture better than many Penstemon species. Still, good drainage is best with little summer water once established. Plant in full sun to light shade in hot regions. Very cold tolerant. Penstemons are attractive to hummingbirds, bees and butterflies.
Penstemon venustus
This jewel of the mountains displays richly toned, trumpet-shaped flowers of blue to lavender held on stalks reaching 1 – 3 ft. tall. Dark green, serrated leaves form a low mound up to 2ft. wide over time. Hummingbirds love the tubular flowers as do bees. Plant in full sun with excellent drainage and water infrequently. While native to much of the West, this penstemon doesn’t quite make it into California.
