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.

The Growing Reality Check

Here’s where we need to be honest: specific growing information for this exact variety is quite limited in standard gardening resources.

Penstemon palmeri var. eglandulosus is also known as...

Often we refer to plants by their common names. When shopping for plants the scientific name is the best way to positively identify the plant species you desire. But some plants have more than one name! While it doesn't happen often, nurseries might display one name while you're searching for another. Penstemon palmeri var. eglandulosus is also known as:

Penstemon palmeri Gray ssp. eglandulosus | USDA symbol: PEPAE

Why do some plants have more than one name? Over time plant species may be renamed for a few reasons:

  1. Botanists in different regions named the same plant without knowing it had already been classified.
  2. A species was reclassified after scientific advances in, for example, DNA analysis.
  3. Slight variations within a species are sometimes mistakenly identified as entirely new species.
