Scented Beardtongue: A Rare Native Gem for Desert Gardens

Meet the scented beardtongue (Penstemon palmeri var. eglandulosus), a delightful native perennial that’s quietly making a name for itself in the world of native gardening. This lesser-known variety of the beloved Palmer’s penstemon brings all the charm of its beardtongue relatives with its own unique characteristics that make it a special addition to the right garden.

What Makes Scented Beardtongue Special?

This native beauty is a true perennial forb, meaning it’s an herbaceous plant that comes back year after year without developing woody stems.
