Size: Flowering crabapples vary greatly in size. At maturity, certain cultivars will only attain a height of eight feet, while others will tower to heights greater than 40 feet. However, most flowering crabapples reach mature heights of 15 to 25 feet.
Fruit: Apples and crabapples are in the rose family, Rosaceae, in the genus Malus. Crabapples are differentiated from apples based on fruit size. If fruit is two inches in diameter or less, it is termed a crabapple. If the fruit is larger than two inches, it is classified as an apple
Flowers: Depending on the cultivar and spring temperatures, full bloom could occur as early as late April or delay until mid-May. Flowers are classified as single (five petals), semi-double (six-ten petals), or double (more than 10 petals).
