Perennials

Penstemon 'Garnet'

Garnet Beardtongue

Penstemon 'Garnet' is a beautiful perennial known for its deep, ruby-red tubular flowers that bloom profusely from early summer to early fall. The vibrant blooms are held on tall, slender spikes and attract hummingbirds and bees, making it a favorite in pollinator-friendly gardens. The contrast between the rich garnet-colored flowers and the glossy green foliage creates a lovely display.

Originating from selective breeding to enhance flower color and bloom longevity, 'Garnet' is a popular choice for borders, cottage gardens, and mixed perennial beds. Its long-lasting blooms and ability to thrive in sunny spots make it a standout in summer landscapes.

Design tip

Late flowers extend the season, so set it behind or beside plants that finish in midsummer. Because it is easy about light, use it to carry a planting from a sunny end of the bed into the shadier side.
