Penstemon ‘White Bedder’
Frost hardy and evergreen, this is perhaps the best white flowering perennial we know. Penstemons are such tough generous plants flowering their hearts out for so long that we can take them for granted. They seem to need replacing every 4 or 5 years by removing rooted side shoots. Evergreen and 60cm x 60cm. A little summer watering but superbly drought-hardy in most regions once established.
