You made good progress.
My timescale resolution is course compared to yours.
The plant lifetime is normally 15 iterations, each growth step is about
0.02.

My interest are complete landscapes, a normal number for plant count is
therefore 200.000 to 300.000, if you count the visible ones only. This
means you need about 2-3 millions of plant coordinates for the whole
heightfield. Your approach seems to be able to handle such numbers.
