Plant this Dry shade – every gardener’s achilles heel – is no problem for Mrs Robb’s bonnet. Ignore the Downton-esque common name – Euphorbia amygdaloides var. robbiae is a tough old boot of a plant that produces beautiful lime green flowers in spring atop glossy evergreen leaves. It will spread, but is far more picturesque than dry bare soil. Handle with gloves to avoid its milky sap which is a skin irritant. Height and spread 1m x 70cm.

Check this One of May’s finest pursuits is spotting fine wisteria specimens in full flower. But if you are unlucky enough to have non-flowering wisteria, this RHS video should help: https://is.gd/wisteria.
