Spires of tubular flowers of blue, stained purple, help Penstemon ‘Stapleford Gem’ stand out in the garden. The flowers share a pout with the thicker petals of foxgloves, but have more of a luminescent quality. Purple beelines draw our eyes down the pale throat into the flower.
Some very reputable UK nurseries are selling this plant by the name of Penstemon ‘Sour Grapes’ but the RHS advises us that this is a misnomer.
