I believe that this chamomile. But what type and is it edible? It's growing all over the back yard and I'll toss some in for my Russians if it's something they might like.
Pineapple weed is another name for wild chamomile. There are little tiny white petals at the base of the flower head (the yellow part) but you have to get pretty close to see them.
It's safe in moderation; my tortoise won't eat it. (She won't eat regular chamomile either.)
