Penstemon 'Willy's Purple' is a wonderful tall penstemon growing up to 150cm tall. I have it growing outside the window of the kid's bedroom and next to a Cardoon which gows to 2.4m tall, it looks fabulous. During the warmer months, it is just covered with purple bells. Great for the back of the border or anywhere where height and colour is needed.
