Penstemon are reliable perennials producing an abundance of flower for most of the Summer months and well into the Autumn.  They are easy to grow as long as drainage is good over the wetter, Winter months and that they are not pruned until Spring.  They are a worthy addition to any flower border.

'The lesson I have thoroughly learnt, and wish to pass on to others, is to know the enduring happiness that the love of a garden gives.'  Gertrude Jekyll
