The Monoblooma is a limited, single-harvest, uncommon crop, added during the Zen Event.
The Monoblooma could be obtained from the Zen Seed Pack or Exotic Zen Seed Pack.
The Monoblooma appears to be a monotone-coloured flower supported with a green stem and a leaf. A white stem is protruding from the middle of the flower. The seed appears to be half pale teal and half black, split vertically. On the teal side is a smaller black rectangle extruding from it's center. On the black half, the same pale teal is a smaller rectangle and is also extruding from the center.
