The Dandenong Ranges Botanic Garden (formerly the National Rhododendron Garden) is host to brilliantly coloured blooms of rhododendrons, azaleas, camellias, cherries and daffodils. Seasonal changes ensure the gardens are a delight all year around.

Like many notable early settlers the Chirnsides were members of the Acclimatisation Society, an organisation which introduced several European flora and fauna species to the Australian landscape. As a result the ten hectares of manicured landscape contain a variety of exotic species combined with Australian natives.

The Werribee rose garden is separated from the mansion's formal gardens by a Heritage Border featuring unusual and historic roses from around the world. In bloom from October to May, the roses are at their most magnificent from November to April.

Take a quiet, peaceful stroll along the many walking tracks and roads of the Arboretum and take in the tranquil beauty and stunning scenery across the Yarra Valley out to the Warburton Ranges and beyond.

Situated in a ferny glade in the Dandenongs, William Ricketts Sanctuary is a place of beauty and tranquillity, due both to the natural setting and the mystical sculptures half hidden among ferns along the pathways. It is a place for quiet reflection and for contemplation of the essence of the vision of William Ricketts. Many travel across the world to visit this place time and time again.

The gardens will delight all year round. In Spring, it is blooming with rhododendrons, azaleas, camelias, kalmias and flowering cherries on the lake. Summer is the time to see hydrangeas, fuchsias, native ferns, rhododendrons and native terrestrial orchids. In Autumn the foliage of maples, beech and the famous golden ginkgos on the lake is stunning. In Winter you will see camelias and the early rhododendrons.

Designed to take advantage of the steep slopes, the terraced garden of Pirianda is distinctive for its combination of botanically important trees, shrubs and perennials with an over storey of large blackwoods and mountain ash towering over the natural fern gullies.
