Dazzling blue penstemon, which — if you like bright colours like I do — knocks the socks of any of the others with a pure, boiled sweet clarity. And hugely long flowering from late spring to winter.
Care Tips
Leave the current seasons growth on over winter to provide protection and mulch around the base of the plant in autumn with compost or leaf mould. Cut back old growth in late spring as new shoots are appearing.
