Yellow(?) Beardtongue, Penstemon confertus

Submitted by Lori S. on Wed, 03/03/2010 - 23:37

Penstemon confertus is a plant of meadows and open woods here, according to Flora of Alberta. The common name always throws me, as the numerous plants in my yard, all are white-flowered! I can sometimes imagine a very faintly yellowish tone, but I find it puzzling that the above-mentioned reference refers to the corolla as "sulfur-yellow"... ? What am I missing? ???

It's a very good, long-lived plant here in our cool, dry conditions, though clearly not so flashy as some of the to-die-for blue-flowered penstemons. If one could fault it at all, it is only that the spent flowers turn brown amongst others still in full bloom, but having said that, it is definitely welcome in my garden.

Lori, I agree with the naming on this one, saw lots of P. confertus in Washington State and elsewhere, always a pleasant plant as you say, but never found a strong yellow one, it always seems to be more of a cream color.  Many years ago, I grew a range of the Bruce Meyer hybrids in which he used P. confertus, and some where fairly dwarf with nice yellow and peachy pink colors, I don't think these exist anymore.  Your large clump of confertus in your last photo in nonetheless an attractive plant.  In the first photo, what variety of Antennaria is that?  I've never seen one so dense with flowering stems, and nicely pink-hued to boot.

Definitely P. confertus. Much yellower and showier and nicer is P. flavescens in the high Idaho and Montana mountains around the Lolo: fabulous plant. Unfortunately, all my pix are 35 mm transparencies, so you'll just have to take it on faith!

That's a sad picture of Penstemon flavescens: I should sca;n some of mine. I believe I took mine on St. Mary's peak--could have been in Montana. Although we saw it on the Lolo as well: both times I saw it was a long hike. I don't know of anywhere you can drive to it. Which may explain the paucity of pix, and the lack of germ plasm.

It is probably the yellowest true penstemon I know (some of the Keckiellas are yella I know)...

You can find yellow sports of most of the reds that are quite pure, and even Penstemon whippleanus verges on yellow on Mt. Evans (in the otherwise dirty, lemonade albino form).

Hybridizers should work on this hue for this group.

I'll take you up on that challenge if you can get me good strong yellow P. flavescens. 8)

Actually, I'm not too sure of its ID... Antennaria dioica or A. rosea?  I don't know the distinguishing characteristics, but I would like to figure it out.   The basal mat gets to about 1" tall, and the flower stalks are up to about 1' tall.

Lori, Isn't rosea just a form of dioica? Here A. dioica is very common in the wild and you can find all kinds of types. Some with red flowers (or bracts), some with very pubescent leaves and so forth. The type you find for sale is often something called A. dioica 'rosea' with a label showing a plant very similar to your plant, but what you find in the pot is inferior with less hair on the leaves.

Yes, I grew this from NARGS seedex and was disappointed, thought I had a nice yellow Penstemon and here is what I got

I think the plant's only "flaw" is that it's been saddled with an oddly misleading common name, LOL!

Okay, I'm happy to get clarification on that.  :)

I lost my mother plant of P. confertus three years ago, but last year noticed a seedling coming up in the blank spot. This spring it bloomed and indeed it is P. confertus. I'm happy!
