Another way would be, as Christopher Hormann mentioned, to create an
acceleration structure. In simple terms, instead of checking all plants
every time you need to check a given plant's neighbors, you check a subset,
ie the nearest plants within a given radius.

A simple techinque you may be able to try is to divide up your plants into
cubic regions, and only check the plants that reside inside the cube
containing the original plant, plus a certain number of surrounding cubes.

Beutiful work, by the way! I can't wait until you release it :)
