Welcome to the Petersham Horticultural Society

A friendly community celebrating gardening, growing, creativity and local traditions.

Petersham Horticultural Society was founded at the turn of the 20th Century. This most traditional community organisation upholds the local area’s ongoing enthusiasm for planting, growing and crafting. The Petersham Horticultural Society is a not-for-profit organisation run by local volunteers committed to continue its mission to encourage and enthuse families to enjoy plants, gardens and green spaces.

The PHS is affiliated to the Royal Horticultural Society which provides the judges for the horticultural classes at the Summer Show and allows us to award the prestigious RHS Banksian Medal, the highest honour available to our exhibitors and may only be won once in a three year period.

The PHS dates back to at least 1895, but the earliest item in the records is the 10th Summer Show in July 1905, when there were classes for Cottagers and Allotment Holders, Amateur Subscribers and children under 15. The early schedules and minutes of meetings are a record of social history and make fascinating reading and include advertisements for the shops which once lined Petersham Road.

Each year in July the society holds its popular Flower Show and Fete in Petersham. There are hundreds of entries across many classes, including flowers, fruit and vegetables, cookery, arts and crafts and, of course, the junior classes.

We are very pleased to announce that the venue for the 119th Summer Show to be held on Saturday 4th July 2026 will be The Sudbrook School Hall, Bute Avenue, Petersham, TW10 7AX
