On the North Front, discover a vibrant display of exotic plants from around the world.
The Victorian era was renowned for being the time when British explorers set off to the four corners of the world - to seek out and bring back exotic plants.
The top horticulturists of the day created special glasshouses to display these rarities in tropical conditions. In the summer months, the plants were taken from the glasshouses and sunk into display beds in the gardens.
If you head to the North Avenue, you'll find the tropical mound, complete with species including purple leaf bananas, canna lilies, dahlias, palms and bamboos.
