Penstemon 'Knightwick'

News

We're sorry to report, that due to moving and building our nursery, we will have to delay our mail order venture. Availability of plants will be shown from September 2021, for Spring 2022 despatch. Our penstemon and perennials will be ready from April and will be sent out in rotation from order received. Many thanks for your patience.

The nursery will be open to the public during August on Thursdays, Fridays and Saturdays. We will be closed during RHS shows.
