Thanks all will sort it out tomorrow it’s a clump I was given from a friend 3 years ago and gives plenty of stalks so don’t want to lose it. Fascinating though!
Be careful when you cut it to get close to the crown. When they start to develop fully the stem that carries the flower becomes hollow. It is a really good water trap to rot the crown. If you get them early (now you know what they are) the stem will usually still be solid.
