This is all of the markers I would classify loosely as herbs.

I have tonnes of vegetables, fruits and other things on my profile. If you want a marker for a plant that I've not created, I will happily do it in the same style for you if you message me.

This plate has the following labels on it. Fell free to delete the ones you don't want:

Basil

Cat grass

Catnip

Chives

Coriander

Dill

Garlic

Ginger

Marjoram

Mint

Oregano

Parsley

Rosemary

Sage

Tarragon

Thyme

Probably best to print in PETG or something stronger if you have it as they'll need to stand up to weather conditions and moisture in the soil.
