I play on the switch version and I can't find anywhere on the internet how to get or make the distinctive herbs for the gift bag herb gardens, it makes trying to craft blank spellbound and potions useless since I can't find them on merchant's or planting them, please help

We are just trying to follow other peoples hint to plant distinc herbs in buckets on matching sufrface. Tea on oil or Durdanae on blood for eg.
The other option would be experimenting with some matching fetilizer.
