Hi everyone, I don't no wether I'm in the right place or not. I have a beautiful wild flower in my back garden. It is very prickly on the stems and leaves and has clusters of beautiful pinky blue flowers on it. I am sure I have seen it on either gardeners world or A - Z of gardening and am not sure if its poisionous. I remember they said that only a certain insect can go on it as the prickles stop other insects from climbing it. I would love to know the name of it. If it's poisionous as I have 2 dogs and 5 cats. I don't want to get rid of it and would love it to spread round the garden. Any help would be very much appreciated.
