Williamstown Green Thumb Horticultural Society

District 1

About Us

The Williamstown Green Thumbs are an active group of gardeners that love to garden and share our plants, knowledge and time with our community. We are a friendly club and always delighted to be joined by new members. We enjoy learning about current garden practices at our monthly meetings, working together to share our plants at a huge annual plant sale as well as showing our flowers and produce at the Annual Flower Show and Tea.

We are also a practical group that is not afraid to tackle a wide range of civic improvements projects and have established youth gardens to teach youngsters to grow and use plants and produce - we like to get our hands dirty! There's nothing like seeing other gardens to get inspired, so each year we organize local garden strolls and a bus tour to gardens outside our area. We would be delighted to have you join our gardening family for any of our activities.
