Malus domestica is a hardy, deciduous woody perennial tree that grows in cold temperate zones. Also known by the common names Bramley apple or apple, this plant grows best where there is cold in winter, moderate summer temperatures, and medium to high humidity. It is moderately fast-growing, but growth slows with age. Apple trees can live for 100 years or more. Apple trees bloom in the spring, set fruit, and take from 100 to 200 days to reach harvest depending upon the variety. An apple a day is said to keep the doctor away!
