That's such a pretty garden, Neil. I wanted to go to the open days this weekend and planter's palette but had to work. Maybe you could start another thread with some of the pictures you took of the gardens.

Not sure about the 1st one but the others look like some hybrid habs. Unfortunately alot of people have been stung like this ( me being one of them). I bought some plants from hirts garden and every plant was a hab hybrid. Still plenty hot but frustrating.Not one of them looked the same.

Looks like a Clematis.

I adore Angelonia, especially the blue colors. It does beautifully in my rather heavy, clayey soil and northern Alabama summer sun. It requires no dead heading, doesn’t need excessive watering, is disease and pest free. AND, the bees, butterflies, and hummingbirds love it. I’ve watched hummers zoom from the front garden bed to the back, just to get to the Angelonia.
