Hollyhock

Excellent.

What a beauty

There's one like this on the bridge over M25 near me. Darker pink but flowering it's heart out amongst the traffic and planes.

I sprayed this with weed killer last year as its on the edge of a path, it actually looks quite nice there so good job it was a strong plant lol.
They seem to be very tough don't they Thorney, my neighbour has loads on a pile of horrid subsoil ( he's having a new house built) they're huge!

You lucky lady........ cannot grow them have given up trying....

Still growing your double white, still single. Last year cause the white doesn't show against the cream rendering on the bungalow.
