Thanks Mike, Vic.
Know the feeling, Vic.
Think one of my biggest perennial frustration is how few of the penstemons I've planted, over the years, have survived for more than a year or two in our garden. As per Mike, astrantia do fine here, but I've not seen them seed in our location.
Was at Merlin's Hollow, Aurora (our town), On, last Saturday. David was saying that the herbaceous part of the garden has still got lots of blue (delphiniums, giant bellflowers, geraniums, Siberian mint, etc,). It's been so wet, with reduced sun, that it's not started to move on to the hotter flower colours of summer.
A wild Mediterranean region gladiolus.

Wish I'd written down what David said this one was.
Back there in a week, so will ask him again.
I think it's in a bog bed.
