I want to get into growing herbs to hopefully make my own tea out of them and I'm looking for advice.

Im thinking of growing mugwort since I've heard it has cool properties with dreaming. If you've made your own tea before what herbs would you reccomend?

Where should I get the seeds for these? Does home depot sell them or should I get them shipped? Do I just put the seeds in a pot with soil and water daily while it gets sunlight on my porch? How long should I expect this process to take?

Any advice you friends have I could use as I'm just starting this journey, if I could yield enough just to make one cup of tea you have no idea how happy I'd be.
