Some decorative plants to add some green.
The grassy knoll plant(explodonut plant?) from the Norn Meso is an excellent decoration to put natural-looking explodonut patch plant. Special Action 1 cycles through two types.
The desert bush is from the C3 Desert and is sure to liven up even places that aren't desert-y. This is simple and has no Special Actions.
Give the place a tropical feel with the fern from the C3 Grendel swamp. This is simple and has no Special Actions.
Lightly tested. Seemed to work fine. Let me know if any problems arise.
