Plant ID please

I found this in the margins of a field where I was walking the dog.   Field seems to be planted with vetch, clover and a grain.  It is on a long bare stalk about 3 feet high. Stalk like an allium stalk but doesn't smell like that.  I couldn't see its feet due to all the other grasses etc.  Smells lovely and bees like it.  Could someone ID it for me?
