Kyla, have you ever tried wintersowing? That may be a good option for Chamomile; I've had luck wintersowing things that haven't done so well otherwise. Sounds like you're good at raising plants fro seed- kudos on the Lavender! I always have to resort to buying plants.
Oh, and on the Dill- if you make dill pickles, the flowering heads are extra tasty to use- all the sharpness of the leaf, with the depth of flavor from the seed as well.
I've got lots of Basil in the veggie garden right now, but guess the only culinary herb in the cottage garden now is a strawberry pot planted with Thyme. It's pretty, and I have it on a garden table, so harvesting is extra easy and I know there is never dog or cat pee on it, LOL.
