nmoasis said:Arturo, Yes, lean soil. I've killed a couple putting them in the wrong beds. I'm slowly completing a long-winded winter project adding new lean beds to my yard.
Since you are a penstemon expert, any chance you can ID this? I've posted it a couple of times but gotten no responses and can't find a match in the NGA database. I've had it for many years and would love to know her name! Large basal dark green leaves stay green through freezing winter weather and get quite leathery. Spring growth is narrower, paler, softer. Flower spikes about 2 1/2 feet tall.
Sorry for quality; I took these pix several years ago with a cellphone.
Thanks if you can help
Well as of today I'm
very far away of becoming a Penstemon expert!...I would actually run away from being even suggested of becoming one in any field of my existence...
From what I see of the pictures, the plant seems to belong to the rosette forming group of Ps. Not that many bloom in reds. I've got 4 that have bloomed for me:
1.P.centrathifolius that has leathery blue grey leaves: Nope
2.P.cardinalis, that has large rounded basal leaves: Nope
3.P.barbatus, the flowers are much smaller than those pictured
4.P. eatonii, ditto
so that's what I can attest here up to now.
From studying the site provided by the American Penstemon society. (

There could be a group that might fit your description within the section Peltanthera, subsection Peltanthera (15 species): Of these, some are very rare, others have other than red/pink blooms so I'm focusing in those that could be:
1. Penstemon clutei (
https://en.wikipedia.org/wiki/...) It has larger blooms more pinkish that red. Of course colour nuances in pictures are very difficult to sort out.
2. Penstemon floridus (
https://en.wikipedia.org/wiki/...) . The overall shape of the full grown plants is imho the closest up to now.
None of these are in my pot ghetto area . There's a third species that might fit: P.pseudospectabilis.

Unfortunately my P.ps. is still in its pot.
it will bloom for me one day. I'm very interested in this genus because I live in a very sandy desert type of steppe area. I want to generate low water gardens and this genus hopefully will provide some that will adapt well.
This much for now. Many interbreed easily so yours may even be a natural hybrid of wild forms from a nursery where you got the plant. Perhaps as you go through the APS descriptions ( specially the leaves) you will be able to pin down much better. Let me know of your progress as I will with mine.
