Title: Mystery Penstemon
Post by: shelagh on May 30, 2022, 12:00:28 PM

In the 2020 SRGC seed list I spotted Penstemon davidsonii menziesii macrophyllus. I looked it up and found it was a lovely dwarf P. However what has grown is not the diminutive gem I wanted. This is 70cm high, my pictures are not of the best quality as there was quite a breeze blowing. Can anyone please help with an ID.

I’d hazard a guess at Huskers Red.

So called because of the red tinges to the foliage, I believe?

Thanks for the suggestion Graham but all the pictures I've found of Husker's Red have white flowers mine are pale blue with a white edge.

Or a hybrid of…….? It is certainly growing in the same manner that Huskers Red does.

Shelagh,

The flower color and form are right for P. davidsonii menziesii; but you do not have macrophyllus, which is a dwarf form.

Penstemon hirsutus?
