More Information

Description 'Onyx and Pearls' beardtongue (or Penstemon) adds a striking contrast to your pollinator or cut flower gardens! Near-black foliage and stems grow to form an upright and full habit in the landscape. In early summer, stalks of soft lavender and white flowers bloom above the foliage. Similar to a pearl, the flowers look iridescent, with pale lavender hues outlining the bright white interior. This native perennial is sure to catch the eye of gardeners, hummingbirds, and butterflies throughout the summer.

'Onyx and Pearls' beardtongue is tolerant of heat and drought and resistant to pests and disease, making it a breeze to grow, even for beginners! Try planting it in wildlife, pollinator, or cut flower gardens, and you won't be disappointed.

Wouldn’t buy again

These plants didn’t look great upon arrival and they haven’t improved too much. Very puny looking and no flowers yet and they’ve been in the ground for a few months. I’m hoping they look better next season.

Hello! We apologize that you received plants not up to our standards. As we try our best to provide exceptional service, some factors like shipping and handling are outside of our control, and issues like this can sometimes happen.

In regards to flowering and growth, keep in mind that When transplanting young plants from a nursery pot to a garden, the plant allocates more energy to root development instead of shoot development (above ground). It's important for them to develop a robust root system so they can actually absorb the nutrients and water in the soil around them. Then after their root system is more developed they'll invest in their shoots and flower development. They generally spend their first year growing roots in their new home, the second year they have more energy to put into growth, and the third year, they are growing and flowering vigorously. This applies to plants in the garden center as well as plants you purchase online. We hope this helps. Happy Gardening!

Absolute gem!

Onyx & Pearls is an absolute garden gem! Knock out performer, bloomed nonstop for over a month in only four hours of sun. The white/lilac tinged flowers were gorgeous against the dark foliage. I highly recommend this beauty!
