Hi @richard.spicer.7906 How are you? I am jealous of you with all your nice plants I your garden. You must have a big one, garden that is. Lol. I have a small postage stamp size garden. I love penstemon too, got mine in a pot. Will have to put a pic up of it. Sounds like you live a busy life style. I have seen you on FB.
Thanks Simon - I've missed growing penstemon so this was a nice refresher for me. Hopefully I can keep them through winter. It's a fair sized garden but not that big. Needs constant attention and much of it is wild but working through those bits slowly to make new beds. @simon50
