Penstemon heterophyllus 'Catherine de la Mare'

This week we are featuring a gorgeous California native called Penstemon heterophyllus ‘Catherine de la Mare’. True to its common name ‘Foothill penstemon’, this plant decorates hillsides with tubular violet-blue blooms and glossy green lance-shaped foliage. Individual plants have low, open growth habit, spreading about 2 feet in width with the impressive flowers sitting atop 1 to 1.5 foot spikes.


‘Catherine de la Mare’ is an excellent plant for borders, patio pots, and native flower gardens. Pairing with warmer colored flowers like California poppies and yellow lupine can provide lovely contrast in your garden space. Blooms typically appear in early May attracting hummingbirds, butterflies, and bees throughout the summer months. Removing spent blooms may encourage a longer stretch of flowering. This plant thrives when planted in full sun to light shade and moist, well-drained soil. Usually little to moderate watering is required, although regular watering is appropriate for potted plants.


The New Sunset Western Garden Book names Climate Zones 7-24 as suitable for growing this Penstemon. We currently have gallon size pots of ‘Catherine de la Mare’ in bud and bloom. To learn more about this plant and the many others we have showing dazzling color, don’t hesitate to call us!
