Beside Lake Colac, Hydrangea House is a charming 1960s mid-century modernist home and garden lovingly developed by owners Ken and Marg over 25 years. Walls of windows connect the home with the garden, lake and spectacular views, creating a wonderful indoor-outdoor experience. Marg’s passion for plants is evident in camellias, David Austin roses, jacaranda, hellebores and shade-loving perennials, while massed hydrangeas tumble through the picket fence. Mature trees create a cool, leafy setting and showcase how a small garden can adapt beautifully to changing conditions. Visitors can also explore nearby Colac Botanic Gardens via the Bird Sanctuary and lake foreshore.
