A list of things that IMO should be added an ability to be planted into Garden Pot
Yellowfeet
Morels
Waybroad
Cavebulb
Blood Stern
Lingonberries
Giant Puffball
Wild Windsown Weed
And maybe (with some longer growth times for the balance)
Bloated Bolete
Glimmermoss
P.S. I've just ran through my storagefor the items which are logical to be planted. And tried them all. So it is not a full list in any way
