Flowering Period & Overlap Window
Apricots flower before peach, plum and cherry, so bloom overlap and spring frost decide most outcomes. Self-fertility varies by origin: many Mediterranean-type cultivars set alone, while several North American releases need a compatible partner flowering at the same time.
Patterson flowers within the apricot Group 2–4 window. Partner-dependent cultivars need a compatible apricot whose flowers overlap in the same days.

Grower Commentary: Patterson as a Commercial Standard
Patterson is a diploid California apricot used for both canning and fresh sale. Our record lists Group 3 bloom, viable pollen and no required partner, and the source note describes it as a heavy regular bearer. It can carry a block by itself, though a second overlapping Group 3 cultivar can extend the harvest or supply a partner-dependent tree.
Heavy bearing is an advantage only if the load is managed. Thin early so fruit reaches a saleable size, and expect to support long limbs in a good year. Bloom is still exposed to frost, and no chill figure is stored for Patterson, so check regional winter records and local performance before planting.
It ripens in the middle of the season. Pick on a schedule that separates canning fruit from fresh fruit, and allow enough labour for a short, concentrated harvest. Confirm the rootstock and irrigation needs with the nursery, and site the block where spring cold air does not settle.
Key Orchard Considerations for Patterson
No required partner recorded; a second Group 3 apricot is optional.
Thin early on a regular bearer to protect fruit size.
Rely on regional winter records for this cultivar.
