I've never considered it hardy enough for me Philippa. Though it would have been OK for the last 2 or 3 winters
True wild flowers like the soil that suits them. Rich, poor, wet, dry. There's no one soil requirement for what man has decided to call wild flowers
I have a new bit of grass, It has Gladiolus byzantinus, 3 different crocus (several of eah), assorted alliums and Iris reticulata
There are wildflowers for all soil types. Not all wildflowers like acid soil. Some do, some don't. Same for wet area or dry area, sun or shade. Wherever you go you'll find that something will grow
I've got one. It grows in a place where roses or clematis would struggle. It's huge with not much to show for it.
Thanks obelixx. Glad to see another supporter of burying the graft
I'll be there Dove, don't worry about giving notice. I might be in the garden but will wash my hands before making coffee.
You have email but I don't think you'll be around early enough to come
Not often I'm first with the flowers
If they look spindly I'd put them close together, 3 or 4 inches. If chunky roots about 6 inches.Make sure all the root is buried. the top at or fractionally below the surface. If the tops have green shoots they need to be on the surface.
That should do it
Do you know what sort of geraniums they are? Some are much bigger than others and you can get a good amount of growth quickly.
