Delivery Options

Our web shop is now open for you to browse and make your selection from. Postage and packing charges depend on the total weight of plants you buy. We only send plants out Monday (not Bank Holidays) to Wednesday. This is to avoid packages being left in the postage system over the weekend. Shipping plants and keeping them healthy along the process is an intricate matter. As we care for the plants we sell we deliver them in a way that ensures they have enough to drink and enough protection between our nursery and your home.

  • Courier Service

    Typically sent out via Royal Mail's First Class Signed for delivery service

  • Click And Collect

    Collection is available from the nursery by appointment only or from one of the events we’ll be attending. During May, June and July our show schedule is very busy so appointments are not always possible and also at other times if we are away attending an event.
