Penstemon for Astounding Blue

I’m an amateur botanist, but I’m pretty sure this is Penstemon glaber and P. angustifolia, respectively. For astounding blues, I don’t think any hybridized plant can beat them. I don’t think I have ever seen a flower with the sky blue of Penstemon angustifolia, a Wyoming native that likes poor, dry, sandy soil.  I was fortunate enough to get one to grow from seed in my old garden.
