This Hollyhock of course, what else would I be talking about?................
It stands 3.30 mtrs tall (just under 11ft.) and has leaves the size of dinner plates!
I haven't cultivated it, it just grew from wind blown seed. I have pale pink and deep purple ones in the front garden.
The tallest UK hollyhock, which belonged to a retired couple in Gloucestershire, grew to a massive 15ft, while the biggest worldwide was a whopping 24ft!!
