The outdoor gardens cover about 23 hectares and contain over 3000 species or cultivars. They are open throughout the year, and are in bloom from April to November.
In the spring you’ll see hellebores, spring snowflakes and several anemone species in flower. In the autumn you can admire the already leafless witch-hazel.
The mild winters and long growing season of the southwest coast allow quite exotic species to thrive in the outdoor gardens. Gingkos (often thought of as living fossils) and white mulberries grow outdoors. A large number of water lily cultivars cover the ponds in summer. The gorgeous colours of the perennials transport the visitor to the warmth and light of a more southern climate.
