Building the Extremes Garden

Wes, our  Head of Horticulture, lets us know what went in to creating our new outdoor showcasing exploring plants with some amazing adaptations to extremely arid environments.

The big challenge to build our Extremes Garden was to find suitable plants to display, as they are not the type that can be picked up in your local garden centre, and we needed something especially striking as a centre piece.

Fortunately my old mate David Cooke, manager of Kew Gardens' Temperate House helped us out, and loaned a Giant African Cycad, Encephalartos altenstenii.

Cycads are amazing plants that survived when the dinosaurs inhabited the planet; they actually predate the evolution of flowering plants and produce cones rather than flowers as reproductive structures.

Glasshouse manager Kate Pritchard from Oxford Botanic Gardens also kindly loaned us two lovely Organ Pipe Cactus that have also made a big visual impact on the garden.

Other plants came from Southfields specialist cacti nursery; gold medal winners at Chelsea this year. The amazing Architectural Plants Nursery in Horsham also provided us with a nice selection.

We paid a visit to a private nursery/collection owned by Cacti expert John Pilbeam (Connoisseurs' Cacti) to source the remaining smaller specimens.

After a lot of deliberation we positioned the plants. They were planted in their pots because they are only going to be on display until September (when they will need to be moved inside for the Winter) so it saved disturbing their root balls which cacti in particular don’t appreciate.

We then laid a weed-suppressing membrane around the plants and over the surface of the bed, creating a patchwork between the plants.

We then mulched with 5 bulk bags of decorative stone, to give the display its arid/desert look.

The display only really took the highly skilled Gardens team 2 days to install, and we are very pleased with the results.
