A pomelo is a citrus fruit with a thick rind, sweet juice, and bitter membranes. They are very popular as a desert fruit in Hong Kong. A grapefruit is a hybrid of a pomelo and a Mandarin, and an Oroblanco (our tree) is a hybrid of a grapefruit and a pomelo, creating a complex sweet - bitter flavor.
This tree is the favorite of several people on campus.
Many of the pomegranate trees on campus were here when APU aquired the property and relocated to make room for Ronald and Wilden. They typically ripen in the fall into winter. Ripe fruits often split after rains. We don't know the variety, but they are smaller and a bit more sour than the newer Wonderful trees on campus.
A note about HLB (Citrus Greening) disease: HLB, or Citrus Greening, disease is an introduced disease that causes severe crop losses and death of citrus trees. It is caused by an insect-vectored bacterium. The APU campus is in a quarantine area to prevent the further spread of the insect and bacteria into other parts of Southern California. You are encouraged to eat campus-grown fruit while on campus. If you choose to take fruit off campus, please remove leaves and stems and wash the fruit prior to leaving campus.
Most of the peaches on campus (white and yellow varieties) are mid- to late-season varieties that ripen in late June through early August. The large tree in the Alumni House lawn is currently being reworked into a multi-graft tree using early season Desert Gold and Flordaprince scions, which ripen during the last weeks of the Spring semester.
Nectarine trees can be found on the edge of campus south of Building 28 and in the south fence of the bullpen. We believe the bullpen tree is the result of a baseball fan bringing a Snow Queen nectarine (a common backyard variety), dropping the pit, and possibly getting an assist from a squirrel to bury the pit in the fencerow. Whatever the story, an 8 foot tall tree was discovered in 2022, and it proven to be a very productive tree with tasty fruit,
June bearing strawberries, which have fruit from late May through early July, are established on the north side of Engstrom and in between some of the administration mods.
Day-neutral strawberries, which have fruit almost all year round (with limited production in January through March) are established in the community garden, around the trees in the Alumni House lawn, on the south side of the Faculty Quad, and on the 2nd floor of Segerstrom.
