Delivery Options

Our web shop is now open for you to browse and make your selection from. 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.
