Describe the bug
The blocks that make up BYG's giant flowers cannot be composted. This includes all petal block colours and the stem block.

To Reproduce
Try to compost any of the huge flower blocks, or
View uses for any of the huge flower blocks in REI. (You cannot, because there aren't any; ego, no composting recipes. :p)

Expected behavior
The petal blocks and stem block would be able to be composted.
Their compostability chance should probably be pretty high, somewhere around that of nether/warped wart block due to being somewhat similar structures. If they have only a low chance of composting, they wouldn't be useful for composting relatively to other, more easily obtained compostables.
