The Green Water Apple Plant, like other apple trees, requires a cold winter period to set fruit and grows best in temperate climates with moderate temperatures and plenty of sunlight. The trees can grow up to 10 meters in height, and produce fragrant, showy flowers in the spring, which later give way to the familiar round, apple fruit. Green Water Apple Plant is one of the many cultivars of apple trees, which are distinguished by their skin color, texture, flavor, and other characteristics.
