PLNT is really annoying, because if there's a flood, it will grow into the water and create a giant mass of plant.
I think there should be a new version of plant (like with fireworks), called LEAF (so it makes more sense to use with trees)
Leaf would be like plant, except it would have limited growth (only one pixel), and when it gets too hot, it drys up and becomes a flammable powder.
SEED: when seeds are planted on DUST or CLST, they grow. In DUST, they make trees (with WOOD and LEAF), and in CLST they make small plants. Tn ANAR, they make upside down trees.
