well I took a look & looked 1st at some choices mentioned here, I'd have to say wrennie is right - feverfew.
it looks just like whats in my book, flowers & leaves.
BUT I still say make sure you ID the plant 100% before ingesting any of it!
case in point, I didnt know this but parsley in excess is toxic, mainly the seeds but could also be the rest of the plant if taken in excess.
so you can see where ID'ing a plant is very important & knowing what parts of the plant is toxic - people make jams/jellies out of some plants that have toxic seeds but the flesh part is safe.
