About us

The Hamilton Dahlia Society is dedicated to assisting fellow gardeners in excelling in growing these beautiful plants. The members enjoy growing these flowers for their beauty and exotic appearance. It is no exaggeration to say that people walking by our gardens stop and marvel at these gorgeous blooms. The HDS hosts a friendly annual competition called the “Show” each September at the Royal Botanical Gardens. We are delighted to announce that we return to the RBG this September 2025 for our show. We hold an awards ceremony at a private dinner in November.
