There’s a lot blooming at this year’s RHS Chelsea Flower Show, but the biggest standout is sure to be Blue Forest‘s amazing tree house. Holding court front and center, the cedar-clad mini-castle is topped with a sophisticated copper turret and surrounded by a lush woodland garden created by Architectural Plants. The cedar tree house has various curved volumes with thin vertical strips of cedar that, along with the turret, creates a mini-castle feel.
