They can be distinguished by flower colour, creamy white in "P. spinosa", pure white in "P. cerasifera". They can also be distinguished in winter by

Its fall foliage is an attractive bronze-orangish-red. Due to its hybrid nature, fruit are rarely produced even though it produces large amounts of pollen, and so it
