Coins depicting different cereal crops, such as wheat, rice etc do not fall under any category except #plant, however this is probably a too broad category for them. So I propose an addition of a new tag:
English: #cereal crops
French: #cultures céréalières
Spanish: #cultivos de cereal
(unfortunately, I don't speak neither French, nor Spanish, so I hope I used a correct term. If not, please correct me)
The parent tag would be #plants
The tag should includes different cereal crops such as wheat, rice, corn and other cereals.
Thank you!
