About Penstemon
Penstemon hybrid is a moderate-growing perennial in the Plantaginaceae family. It reaches around 80 cm tall and 50 cm wide at maturity, with evergreen and semi-deciduous foliage. Red, pink, purple and white flowers appear for much of the year.
Where to grow Penstemon
Penstemon suits cool-temperate, warm-temperate and Mediterranean climates and grows best in full sun. It is frost hardy and shrugs off cold winters. It also is a genuinely water-wise choice.
Soil & planting
Most soils suit Penstemon provided drainage is reasonable. Dig in plenty of compost before planting, water in well, and mulch to keep roots cool.
Watering & feeding
Penstemon is happy on low water, so once its roots are down it needs little supplementary water. A feed in spring with a balanced fertiliser keeps growth strong. In its first year, water deeply once or twice a week to settle the roots in, then taper off as it establishes.
Pruning & care
Prune Penstemon after flowering to keep it compact and encourage the next flush of blooms. Overall it is low maintenance.
Using Penstemon in the garden
Penstemon earns its place for drawing nectar-feeding birds into the garden, feeding bees and pollinators, cut flowers for the vase and a feature or specimen planting.
Companion planting & design
For a cohesive, low-care bed, pair Penstemon with other plants that enjoy the same happy on low water and cool-temperate climate. Group three or five together for impact rather than dotting single plants through the garden.
