I planted chamomile seeds on the hugel bed. In addition I have some kind of weed on the farm that looks a lot like the chamomile, either mayweed, or some other look a like.
I guess I can take out a tea bag and see if I can smell what chamomile smells like... but does anyone know how to tell chamomile apart from all these imposters. There are SO MANY names for the weeds. False mayweed, scentless mayweed, yadda yada. Maybe I shouldn't try to grow chamomile...
I have two thoughts for you. Hope they help a bit.
The first is, rub the flower between your fingers and smell. Chamomile smells like a sort of flowery apple to me.
The other is, if you have a smartphone, take a picture of each plant. There's a button you can press that will match your picture up the best it can to a database (possibly google images) and help you identify it. I find I need to take a couple pictures... close up of the bloom is good, and one where the leaves show well.
