foot in height, is widespread in what was the previous owners veg
patch so I suspect is edible, I have tried a little and it tastes like
Sorrel, although the leaves are very different.
Has spread over a wide area, not too difficult to remove, but would
like to know what it is before we remove most of it. If it is edible I
will use it rather than compost it!!!
Thanks in anticipation
