Hmm... We had 'Sweet Joanne' at the nursery last year and it bloomed really heavily in pots. No special treatment. I don't think any of us took them home to try though. Will look if we have any still out there. I' interested to try 'Prairie Delight'. We usually have really good luck with the P. digitalis selections - 'Dark Towers' has been fabulous for us. But then, the species grows wild by the roadsides. Maybe our hotter summers help harden them off a bit more than they do for you out east?

Graham, do try Penstemon "Red Husker". I also live in Pa and that is one of my very favorites. Love the burgundy stems and leaves early in the season, they change to green later on.The flowers are lovely white bells with a pink blush. Our Hummingbirds enjoy them too.
I would love to get on a list to try plants, you are so lucky.

Yes, gardenercaleb and louise h, I've grown both 'Husker Red' and 'Dark Towers' and both do very well in north east PA. 'Prairie Delight' is much shorter, which in our border is very useful, and has real style. It will be interesting to see for how long it flowers...

'Sweet Joanne' is going into its third year in my garden (z6 Ontario), and has done remarkably well, flowering prolifically right now, and then somewhat less for the rest of the summer. No problems with hardiness here.

Graham Rice

Good to hear that 'Sweet Joanne' is doing so well in Ontario. We're z5 so I suppose it's just too cold. But it never flowered anyway, in spite of its strong growth.

'Sweet Joanne' is the best Penstemon I've ever grown. It has been blooming constantly since May. It's now September and the plants are still loaded. I have never seen a Penstemon bloom so much. It is a nice, compact plant too.

Graham Rice

Thanks Clint, that's really interesting - where do you garden?

Clint

I'm in West Tennessee. I have it in full sun. It was a very hot summer this year. I am going to plant more of them because it looks very good behind my Ice Plant edging. Give it another chance. It deserves it!
