Hello. Can you ID which species of Penstemon this is? My best guess was Penstemon gracious but I’m not sure. Thank you.

Expert Response

There are over 250 species and many more cultivars.
There are a few nurseries in the Jackson - Mason - Howell area that are experts in perennials.  http://www.nurserytrees.com/States/state%20Michigan.htm
It may be worth a visit to their nurseries to compare your plant with what they grow or to see if they have seen this variety.
The following two sites may help. Both sites also have lists of nurseries that specialize in penstemon.  The University of Nebraska has a list of named cultivars (which is ever growing) at: https://digitalcommons.unl.edu/cgi/viewcontent.cgi?article=5797&context=extensionhist

The American Penstemon Society and they do have identification keys to the species but not to the cultivars. https://penstemons.org/index.php/identification
