Choose this drought-tolerant penstemon for sunny areas in low-elevation gardens (under 5,000 feet).

This penstemon’s most striking features are its flowering spikes, which bring a welcome touch of pink to the garden in late winter on into spring, and are sure to attract the hummingbirds in the neighborhood.

The base of Parry’s penstemon is made up of a rosette of narrow, blue-gray leaves that are 4 inches long and 1 inch wide. When not in flower, Parry’s penstemon, like other penstemon species, is rather unremarkable and blends into the surrounding landscape.

Impatient for spring, it begins rapidly growing in late winter; the spikes begin to grow and flower buds appear, giving a hint of the pink show to follow.

The flowers of Parry’s penstemon can vary from light pink to dark magenta. The beautiful flowers delight not only the people who view them, but also the hummingbirds who feed on them. Parry’s penstemon begins blooming in mid-February and continues on into April. Pruning the flowering spikes just as they begin to fade will stimulate a new flush of blooms, although the plant will be smaller. Noelle Johnson Landscape Consulting When treated as an annual, Parry’s penstemon seldom needs supplemental water and can be left to go to seed, producing new plants for the next season.

For those who want to grow this penstemon as a perennial, supplemental water is needed for it to survive spring through fall. It’s important not to overwater, which can cause the plant to flop over when in flower. Too much water is also a frequent cause of root rot with this penstemon. Providing water twice a month in spring and fall with weekly watering in the summer is enough to keep it alive throughout the year. Noelle Johnson Landscape Consulting How to use it. Parry’s penstemon is best suited for informal planting areas and looks great in a bed filled with annual wildflower favorites such as California blue bells (Phacelia campanularia) and California poppy (Eschscholzia californica).

In a more permanent spot in your garden, plant it alongside other flowering perennials, such as angelita daisy (Tetraneuris acaulis), blackfoot daisy (Melampodium leucanthum), desert marigold (Baileya multiradiata) and desert primrose (Oenothera deltoides).

This versatile perennial also looks great when planted near cacti and succulents like common sotol (Dasylirion wheeleri), golden barrel (Echinocactus grusonii) and Santa Rita prickly pear (Opuntia santa-rita). Noelle Johnson Landscape Consulting Planting notes. Plant it in full sun or filtered shade. Well-draining soil is a must, so it’s best to amend heavy clay soils with compost before planting. No fertilizer is needed.

Prune spent flowering spikes in late spring. Spread the seed in wildflower garden areas or save some to plant in another area of your garden. Parry’s penstemon is also available as a transplant in 1-gallon and 3-gallon sizes.
