Previously, maximum flora density was chosen based on the extremely rare occurrence of all 8 flowers being at high density at one location. This caused flora everywhere to spread to an unacceptably high density. Revert the threshold to 3, which in testing results in a more acceptable maximum density of 7 flora per 9x9 area.
