The namesake display at the Arctic-Alpine Botanical Garden makes for one of the most unusual gardens in the world, capturing nature as it triumphs in adverse conditions. Discover bright flowers growing from craggy rocks or hardy breeds from the deserts of Chile thriving in flower season – from May until first snow in October. As climate change affects the Arctic’s ecology, there’s no telling how long plants like these will be in bloom in the wild. Time your visit for June when you may chance upon ‘Rhododendron Valley’ serving up a surprising riot of colour.
