The warm spring weather in the UK has meant lots of plants are flowering earlier than usual. The barberry flowers are bright yellow and are out in some parts of the UK already. It does make finding a barberry bush much easier as other hedgerow bushes tend to have white flowers at this time of year. If you do see a barberry plant and can easily access it, please also look out for small orange dots on the leaves. This is likely to be rust aecia. You can include this observation on the BarbRE observation page. Happy Barberry Rust Exploring!
