Penstemon Sour Grapes
Penstemons flower over a long period from mid summer to the first frosts.
Sour Grapes is a large leaved variety with rich purple flowers that last from midsummer to mid autumn helping to attract beneficial insects to the garden. Plant in well-drained soil in sun or partial shade. It is worth taking a few cuttings in late summer to overwinter indoors as an insurance policy as plants are not fully hardy.
We are offering this penstemon in a 2 litre pot.
