About
The fresh green, trefoil leaves of wood-sorrel form distinctive clumps in woodlands and shady hedgerows, often growing from the moss on fallen logs. Rising from these cushions, the delicate white flowers hang on tiny stems, blooming around Eastertime and giving rise to its popular European name of 'alleluia'.How to identify
Wood sorrel has distinctive trefoil leaves - at night, the three, heart-shaped lobes are folded back into a tent, while during the day, they flatten out. The white flowers have five petals and tiny purple veins, they also close as the light fades, reopening in the dappled sun.Distribution
