The previous owners of my house left me a bush of shrub of lemon balm and sage... They are of significant size and especially the sage I use basically weekly for various recipes.

Chiming in with Catnip. I grow it for my cats, Its a super easy grow(mints just seem to be easy plants). They love hanging around it and eating the leaves and flowers. If you have cats its definitely worth a try!

Ive heard of people using it in teas as well but I’ve never tried.

Rosemary and bay leaf. They grow so well here in Ca, it’s criminal that they sell the leaves at 8 dollars a pop at most stores.

I most often use the parsley from my herb garden. It's in so many recipes that I make! Also love rosemary. My rosemary has died each winter so I replant every year

I like basil. At some point I i got tired of killing all the plants and started learning how to properly grow and care greens with basil.

It has plenty of uses and it requires the right amount of care, not too simple not too complex.

I’ve grown it from seeds, cuttings, in pots, outside and in hydroponics.

I second basil. I have been trying to propagate rosemary into small containers; rosemary and lavender are easier to grow from cuttings than from seed. I grow dill in small containers, too, but it is not really my favorite.

Mint (in a bucket). I harvest and dry it and use it for mint tea throughout the year.
