NY9 Plum Tree

The NY9 plum tree, also known as Kenmore, was developed by Cornell University in 2009, renowned for its self-fertility, high productivity, and disease resistance. Medium to large plums with deep blue skin and yellow-green flesh ripen in early September, making them an excellent planting choice for orchards and gardens in USDA zones 5-8.

General Tree Height/Caliper: Most of our fruit trees (apple, peach, apricot, plum, pear, nectarine, quince, and cherry) are grafted/budded and are 4-6' tall with a caliper/diameter of about 1/4-3/4". Most have more than 5' height and 1/2" diameter. The other trees are seedlings, such as pawpaw, mulberry, persimmon, shade, berry, and flowering trees which range from 18-36" tall.

A rootstock primarily controls a tree's size and how early it bears fruit. Learn more about our specific rootstocks.
