The St Albans Butterfly Challenge 2023

We officially launched our St Albans Butterfly Challenge at the Growing the Greenhouse event on June 11 2023 at the George Street Canteen. It was a beautiful day and the wildlife garden was buzzing with life. A perfect place to enthuse people about butterflies and how to attract them!

Our challenge involves all of us growing in our gardens or on our patios the favourite food plants of a selection of 7 butterfly and moth species. These have been carefully chosen for us by Malcolm Hull from Butterfly Conservation, who opened his butterfly friendly allotment to the public during Sustfest.

Our 7 selected species are:
