Orchids

I love this clump of orchids. I bought them from an open garden in Broughton a good number of years ago. They do not seed and have to be split up to make more clumps. They are not wild orchids but cultivated ones.
Today started off wet but it dried up and I was able to get out to spray the weeds with weedkiller. Now I have to wait three weeks to see if it as killed them. There are so many of them there is no way I could weed by hand.
