Reviewed 10th June 2016 by MW

I planted three plants last Autumn (in front of a west-facing fence in a sheltered position), did nothing to them and they're in bloom now (Llangollen, half-way up a hillside, it has been hot and dry for a fortnight) standing about 40cm tall. Talk about easy gardening, though I understand I'll have to prune in spring. My soil is very free-draining, I added a bit of manure. It has been in flower for at least three days, I spotted it from a distance and thought it was forget-me-not but up close it's lovely, sky blue with hints of violet. It sort of reminds me of the Mediterranean, or maybe it's just the weather, I hope it likes it when we're having a more British summer. It has delicate bells and a semi-wild look I prefer. It's part of a bed I have to fill up opposite the bedroom windows and I want in restful purples, graduating from blue to reddish. I think having this success will give me the motivation to tidy it up and do some more planting. The blackbird penstemons aren't out yet, they are a bit more exposed to easterly/north winds in their position.
I'll be delighted if they last through the autumn and come back year after year. £6.50 well spent I'd say!
