beryl.I saw my first butterfly in my garden yesturday. it few under the garden table and I didnt see it again to know what kind it was, not even the colour. so, after growing some stinging nettles, budlia, two kinds,two blue and one yellow,( the blue is beautiful this year) , i did as I was told and cut them back last year,it certainly has paid back, they are lovely. But so far only ONE butterfly, I hope they return for the stinging nettles??. I think they will, when the sun shines hot for a few weeks.
