Herbalist in Houston

Does anyone know where I can harvest herbs in the Greater Houston area? I don’t mind a bit of a drive. Or where I could find a lot of dried herbs?

Specifically, I’m trying to craft my own teas and salves so I’m not looking for spices (like saffron), rather, herbs like Anise Hyssop, Geranium and jojoba wax or candelilla wax?
