Honey Garlic, a rarity

Been back to Kirkley Fen to see if this unknown Allium had flowered. I was lucky enough to see many panicles drooping from the bulbils. It was soon evident I had found Nectaroscordum siculum (Honey Garlic.) A lifer for me. It i slocated near to the pump house and as it flooded out recently I wonder if it was washed down to here from garden waste. Allotments are nearby.
