This perennial hollyhock produces bubble gum pink flowers that are almost double in late summer, on tall stems with a branching habit. Butterflies and bees love it.
A stately plant, it is great for adding vertical structure and impact at the back of a border. Ideally it prefers good soil in a sunny position that occasionally gets some shade. To maintain a good shape, pruning down to 5cm from ground level after flowering will help.
