Rochester

Later-flowering than Peregrine and reliably hardy, which is why it is the other name that comes up for an outdoor British peach.

A cultivar of Peach. Everything on this page is about the cultivar; how to grow the species is on the plant page, and how big the tree gets is on the rootstock page.

What that means in practice

Self-fertile and slightly later-flowering than Peregrine, which is a real advantage where frost at blossom is the recurring problem.

Partners for Rochester, from the 2 peach cultivars GrowingHQ holds

Computed by the pollination engine from the flowering groups, ploidy and recorded pairings on each record — not a hand-written list. The scope is exactly what the heading says: these are the answers that exist in this catalogue, not the answers that exist.

No partner is required

Rochester sets a crop on its own pollen. The table below is still computed, because a compatible neighbour does no harm and a grower planting two trees may want to know which pairs work.

No compatible partner in this catalogue

That is a statement about GrowingHQ’s coverage rather than about the cultivar. A nursery list will contain compatible cultivars this catalogue does not hold — the pollination mechanisms page explains how to work one out.

1 further cultivar returns no verdict, because a flowering group or an incompatibility group is not recorded on one side. The engine reports that rather than assuming a value: Peregrine.
