Allium siculum-Bell shaped blooms

Now called Nectaroscordum siculum, but never mind. They only get the one flower stem per bulb. Either cut them off when they have finished or leave and let them seed themselves around. It does take a while for the big one to reach flowering size from seeds. There is a smaller version, which is an absolute thiug, spreads by seed and tiny bulbs. Smells wonderful though.
