We didn't find it.
We have a patch at the top of the garden which is dry and never gets the sun. Due to the fence and overhanging trees.
Its not the best of sites.
We visited a couple of garden centre and they all claimed to need full sun or part shade. This isn't even part shade.
We searched and searched.....
Lovely flowers but not what I'm looking for.
We might settle on a few of these. The patch isn't very big, so its might well be do-able.
I'll let you know.
