Penstemon Sour Grapes AGM
Elegant stems bear spikes of tubular flowers, which can vary between magenta to soft violet-blue.
No garden is too large or too small for a few penstemons. Equally at home in formal borders, a cottage garden style setting or in pots and containers, they are hugely floriferous and reliable. We’ve chosen some of the best ones which always perform well year after year.
Grow in fertile, moist, but well-drained soil in sun or part shade.
