Take a walk in a woodland during spring and you're almost bound to see the delightful plant, wood sorrel (Oxalis acetosella).
Indicators of ancient woodland (as well as imminent rain!) the lush-green clover-like leaves of wood sorrel are currently carpeting woodlands everywhere. Most often in bloom in April and May, the dainty, delicate flowers have five white petals, streaked with lilac or purple veins.
Although they can be spotted at any time of year this is the time to see them at their best: when the tree canopy remains open. They are perhaps at their happiest nestled in amongst moss 'cushions' that cover fallen logs on the woodland floor but they can also be found under hedgerows and on banks, though usually in mainly shaded locations.
Lovers of woodland's dappled spring light, those verdant leaves open up their beautiful heart shapes to bask under warming sunshine rays, but fold right back on themselves the moment rain is due or the day's light begins to fade.
In small quantities wood sorrel is quite edible: add a small dash of leaves to a salad for a delicious, zingy lemony citrus flavour, which is packed with Vitamin C.
