New to herb gardening - what to start with?

Hey, all!

I'm relatively new to actually practicing, and after using what herbs I can get at grocery stores, occult shops and online, I decided to bite the bullet and grow some things on my own.

My thing is, though - I'm a little overwhelmed about where to start! So many books, so many herbs and flowers to choose from.

Any tips on which books are the most helpful? And which plants I should focus on first? I know rosemary is tip top on my list as I use so much in my craft, but any ideas anyone has for newbs just getting their feet wet is much appreciated.

Thank you!!
