Floricraft adds a slew of new flowers and floral effects. You can now stack flowers together and hang them along the walls.
You can also craft a full cloth armor set that grants speed II when wearing a full set.
And if you craft a sachet you can use it to repel various mobs while holding it. You can also carry a sachet holder to hold multiple sachets at once.
Silage bales of hay are also very useful in taking care of livestock. If you place them in a pen, it will cause animals to reproduce automatically.
And what would make a floral-based mod complete without a flowerland filled with roses?
