Penstemon 'Stapleford Gem'
A stunning variety that always draws comments, this would have to be one of my favourite colour combinations. Healthy, clump-forming plants and multiple long spikes of large bells, each one being a lovely pale lilac blue inside, with darker lines in the throat, and the outside is a changing combination of lilac and shimmering azure blue. Just beautiful! Repeat flowers from late spring right through until winter. Cut the spent flower stems off near the base to keep it bushy. Full sun. Height 60-90cm x 60cm wide. 1 litre pot.
