The ultimate size and splendor of the garden depends on how many of them contribute. Furthermore, although each player is happy to have the garden{and happier as its size and splendor increase{each is reluctant to contribute because of the cost that she must incur to do so.

However, if one or non contribute, it will be too sparse and poorly maintained to be pleasant.
