Not heterophyllus - is it venustus?

In my continuing saga of mis-ID'd penstemons, here's the offspring of some seed (not from the NARGS exchange) labeled P. heterophyllus. I grew that one before, and am pretty sure this is something different. It resembles the P. venustus I grew more recently, although these new plants are bigger; they were evergreen (or greened up early in spring) in my zone 6 garden, and tended to lay themselves down, rooting along the stem. I like it.

If not venustrus is could be serrulatus...I grow that one and it looks quite similar to your photo.

Venustus. Serrulatus has smaller flowers.
This is one of my favorites.
