One of the gardens I work in has a really long border made up of really really dry shade. It gets at most 30 minutes of direct sunshine a day when the sun peeps through the buildings it is surrounded by. Over the last two years I have read lots of shady space books and scoured the internet for dry shade loving plants that are not too dangerous to be in an area with lots of small children. I have replanted it with a variety of plants at least four times; of course once was because of careless builders dumping scaffolding boards on a month old planting scheme.
My latest attempt was put in, last spring with Hellebores, Heucheras and this gorgeous Astrantia ‘Buckland’. Nothing much happened with it the first year, a few flowers but not the greatest show. I didn’t divide it because it wasn’t looking hugely strong but it has more than made up for it this year. It’s been flowering fantastically for a while and the children simply love it.
