Penstemon ID needed

[Paul]

Hello,  This Penstemon was a seed exchange selection labeled Penstemon rupicola, which I don't think it is.  Can anyone identify it?  I also have a white one from the same seed packet.

Hi Paul. I may well be wrong but as I am also seeking a Penstemon ID, it seems that possibly ( I don't know anything about Penstemon features ) we need to provide more detailed information,.... see here - http://nargs.org/smf/index.php?topic=1327.msg23446#msg23446.

One of the best ways to check out such an ID, is to use resources where the plant is native too, such as the excellent web site, Plants of Washington (State), Burke Museum of natural History and Culture
http://biology.burke.washington.edu/herbarium/imagecollection.php

Browse plants by Plant Genera > Penstemon > click on Penstemon rupicola.  On that plant profile page for P. rupicola, scroll down to see dozens of photo thumbnails, click to enlarge.

Paul, was your SeedEx seed from a wild source, or garden grown source? The woody Penstemon are notoriously promiscuous, and garden collected seed is very likely to result in hybrids.  Your plants lack the strong glaucous leaf coloration of P. rupicola, and the low tight growth, most likely a hybrid with P. fruticosus or cardwellii, or others in the Dasanthera Penstemon group.
