Penstemon ID needed

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.  :)

53.69° N, Dedicated to West Coast Fritillaria, plus three other members of the subgenus Liliorhiza. I grow other Genera, as time permits !

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.

Don't think this a penstemon although the flower is similar.  The species if pyrenaicum but can't remember the genus??  The two other pics, if they come through OK, are a Hesperochiron pumilus and a tiny trough Hypericum - just because they are so pretty.  Fran

It's been so long since I spoke up here that I had forgotten how to send multiple pics.  However, I think they will come through this time.  Fran

Frances, your blue-flowered plant is Horminum pyrenaicum.  :)
It's a very pretty plant, always good to have reliable blue-flowered plants.

Francis Howey's query on a Hebe identification has been split off to its own topic, find it here:
