The PRISTINE® apple is a yellow apple introduced in 1994, noted for its tart flavor and good keeping capability. This cultivar is one of many developed by PRI, a disease-resistant-apple breeding program, which is a cooperative among Purdue University, Rutgers University, and the University of Illinois.

Crabapples are small flowering trees that provide a showy display in the spring landscape for 1 to 2 weeks. In addition to the eye-catching buds and flowers, their foliage, habit, and fruit make them attractive plants almost year round. They are actively hybridized for flower color, leaf color, fruit size/color, shape and, most importantly, disease resistance. Crabapple fruits are usually not eaten by humans but are beloved by birds. Most crabapples benefit from modest amounts of pruning to eliminate water sprouts and improve airflow.
