These will be adaptations for the plant to be able to survive in the very cold winters, as the temperatures are way below zero, and there is lot of snow and ice. This plant will also be capable of minimizing its activity for several months, until the conditions are suitable again. The growth of it will be slow, as the vegetative season is short.
The plant from the tropical rain forest of Belize will have wide and thick leaves. It will be high because there is a lot of competition for sunlight. The plant will be able to stop the intake of water through its roots as in certain periods of the year there's just too much water. It will be highly active throughout all of the year, as it is summer summer for the whole year, and there is sufficient precipitation for most of the year, or even when there isn't there's lot of water around. iT will have a very quick growth.
