In Herbaceous, herb collectors compete to grow and store the most valuable medley of herbs. Everyone starts with four containers, each of which allows a different grouping action:

Group herbs of same type
Group different types
Group pairs
Group any three types (same or different)
On your turn, you draw an herb, then decide to either keep it in your personal collection or put in into the communal pile. If kept, the next card goes to the communal pile; if placed in the communal pile, the next card goes in your personal collection.
