OK, a slight exaggeration on the limited number of plants blooming - we also have this lovely blue plant that I have absolutely no idea what it is. I never bothered making a tag for it, because most gardeners told me that this thing would get amold and die within the first year.
Turns out it's taking over an entire corner of the garden, so I suspect it's not the same plant. Anyway, it's a nice blue which is hard to find
