The ornamental pear and its cultivars, Redspire and Aristocrat are the tallest of the flowering trees, reaching up to 50 feet high. Fauer is the smallest at a diminutive 20 feet tall. The Capital variety is in between, reaching up to 35 feet in height.
Ultimately it can grow to a height of 30 to 40 feet and about one-third as wide. Flowering pear has a relatively short lifespan of 15 to 25 years, many flowering pear trees live only 15 to 20 years because of inherent problems.Although flowering pear tolerates many soil types, air pollution and drought conditions, certain genetic traits often shorten its already short lifespan.lowering pear has a relatively short lifespan of 15 to 25 years, many flowering pear trees live only 15 to 20 years because of inherent problems.
