I have overlooked them for too long. Plants that flower for so long deserve space in every plantsmans garden. I put a couple in as gap fillers last year. These two became six all on their own and have divided with ease again this year, making twenty or so.
Most penstemons are herbaceous perennials. They are very easy to propagate now with semi ripe cuttings. Most of mine have an abundance of cutting material right now. In fact, most have air layered, with early stems having roots on the bottom few inches of stem.
I'm going to look for some interesting varieties for next year to go with my Sour Grapes (pictured) and Etna.
Love gardening.........making the most of that room outside. My favourite room in the house!
