Penstemon ‘Alice Hindley’
One of my favourite Penstemon with the loveliest blue-mauve white throated flowers beautifully poised on long pedicels. Flowering as it does from late spring until winter it has been a mainstay of our double borders for many years. Penstemon are tough plants with very little artificial water requirements. It’s a mistake to cut them back too hard in winter, about half way is safe. We remove old spent stems when the new spring growth gets to 30cm or so. 90cm x 90cm.
