Veined octopuses hide in discarded coconut shells, scientists in Indonesia discovered. An octopus may even carry multiple shells for future use, stacking them like bowls, spreading its arms around the shells and "stilt-walking" with the shells wedged within its eight arms. Hermit crabs use seashells for shelter, but because these octopuses carry their shells for later use, they are the first invertebrates known to use tools.

Not only is the Impatiens pallida known to show kinship with its siblings, White Pines grown on a hillside will alter their height so that the lower pines will grow larger than the pines on the up side of the hill but will reach the same height as those on the top of the hill. Either to ensure reproduction or to provide protection from strong wind gusts which could damage them.
Mown grasses wild or other wise including corn have also been known to also grow in a similar manner. The flowering grasses which have been mown will only reach a minimal height but will come to bloom at that level presumably to ensure pollination. Corn will follow the growth pattern shown above with the pines.
I have a feeling that the above ground conspirancies are not limited to the Impatiens p.seallida
