Hmmmm I did the same thing and despaired of ever getting any chamomile. Probably dumped two packets of seed before giving up!
I just put them in the dirt next to my Echinacea, and now I’m wondering if I might have a surprise coming at me too! I have a lot of leaf mulch in that bed that I have not tried to clear away yet.
Here’s to you getting a surprise! Mine are, knock on wood, the brightest green and very healthy. Don’t know why since they’ve had zero care until the last maybe 3 weeks since they popped up. They survived several nights of freezes with one down to 15.
