Most of the volunteer seedlings from Tanacetum parthenium 'Aureum' revert to Tanacetum parthenium.
Feverfew (Tanacetum parthenium)
These can almost get to be a weed here for me, it is a great little flower for a filler in arrangements but in the garden it will take over if allowed, consequently I pull it out like a weed.
This looks alot like chamomile to me. I can never tell which one I have. One is dome capped and one is flat capped on the flowers, and one has threadleaves, and the other undulating leaves. Both are scented, but which one is better scented???
I also pull these out in the garden, but allow them free reign in the wildland garden outside the backfence. I do dig and transplant the 'Aureum' seedlings and place them where I want them. Feverfew does have a distinct aroma which I find to be not unpleasant, but others think it is "stinky."
