I have abused this poor plant. I later learned they like sandy/rocky soil, so next to the driveway was a good choice. They showed some new growth before the summer ended. This year the Wild Bergamot exploded (!), nearly covering one of the small Beardtongues, so I moved it over a little. In spite of that, this one plant bloomed this year. I planted some other lively natives in that area, so I believe these Beardtongues would be overwhelmed in a year or two.

They were transplanted to another rocky location, but with some sand added, and they haven't died on me yet. We did this before the seed pods could break open and I hope there will be even more in the coming years.

For those who use fire in prairie restorations and maintenance, the large-flowered beardtongue will not survive! In the areas they are found naturally, there is sparse vegetation, so there is little fuel for the fires to consume.

A lovely plant: thick succulent gray-blue leaves and big pastel purple flowers. Likes dry soil and full sun, but is more moisture-tolerant than most of the other succulent penstemons. One of my absolute favorites. It blooms for a short time, but it's worth it.

Longer-lived if you cut off the seed pods (or leave one or two per stalk). Each pod has tons of seeds, and they use up the energy that the plant would otherwise use to prepare for next year's growth. One of my plants has survived for 3 or so years because I clip off most of the seed pods. One or two seed pods have more than enough seed for spreading around the garden to start new plants.

Learned they do not like competition, so moved three away from some lively Wild Bergomot and Hoary Vervain to our Prairie-to-be. They had finished blooming and were setting seed.
