Grassper

The Grassper is a plant from the Witchery mod. This plant allows visual storage of a single item, like the Item Frame. The Grassper is used in various mutation recipes for other plants. Creation of the Grassper is slightly complicated, and four will be created per mutation.

To create them, a chest must be above a single block of water, with a single tall grass block on each direct side of the chest. Then, a Mutating Sprig must be used on the chest. The chest will disappear, and the grass will turn into Grasspers.
