The origins of the Winsham Horticultural Society are shrouded in the mists of time. In such a rural community, it was certain that most homes would have grown their own vegetables for domestic consumption, with no doubt bartering or swapping anything that was surplus to their immediate needs, or could not be pickled, bottled or somehow preserved. It seems likely that Winsham Horticultural Society was formed sometime between the two World Wars, emerging in its present form sometime in the 1950s. Interest in the cultivation of flowers, among ordinary people, probably grew as more people had the leisure and money to indulge in such interests, as standards of living improved, and hobby gardening became a topic of television programmes. But that can only be speculation.

In recent years, Winsham Horticultural Society has organised an annual Summer Show at the end of August. Located on the Upper Recreation  ground it is housed in a large marquee, and offers many categories of exhibits, with a large number of trophies which have been contributed over the years.
The Winsham Open Gardens Exhibition has also taken place in recent years, alternating with the Winsham Street Fair event at the end of June. This is linked to a display of Scarecrows made by village residents to the delight and amazement of all.
It also holds an annual plant and garden accessory sale in the Jubilee Hall every year on the first Saturday in May, together with numerous outings and talks throughout the year, culminating in the AGM in November.
