Jubilee

A Victoria seedling with larger fruit, ripening a little earlier. Chosen where Victoria is wanted but bigger plums are preferred.

A cultivar of Plum. 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.

Partners for Jubilee, from the 11 plum 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

Jubilee 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.

Cultivar	Verdict	Why
Blue Tit	compatible	Both flower at overlapping times (groups 3 and 3) and both produce viable pollen.
Cambridge Gage	compatible	Both flower at overlapping times (groups 4 and 3) and both produce viable pollen.
Czar	compatible	Both flower at overlapping times (groups 3 and 3) and both produce viable pollen.
Merryweather Damson	compatible	Both flower at overlapping times (groups 4 and 3) and both produce viable pollen.
Opal	compatible	Both flower at overlapping times (groups 3 and 3) and both produce viable pollen.
Oullins Gage	compatible	Both flower at overlapping times (groups 4 and 3) and both produce viable pollen.
Pershore	compatible	Both flower at overlapping times (groups 3 and 3) and both produce viable pollen.
Victoria	compatible	Both flower at overlapping times (groups 3 and 3) and both produce viable pollen.

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: Shropshire Prune.

On each rootstock

The size of the tree comes from the rootstock. What the cultivar contributes is a direction, in words — GrowingHQ does not multiply the range by a vigour factor, because no source supports the multiplier and the resulting number would look far more precise than the inputs are.

Rootstock	Height	With this cultivar
Pixy	250–300 cm source Sourced guidancehigh confidence Royal Horticultural Society: Plum rootstocks Checked 2026-08-13	Jubilee is of average vigour, so the rootstock's range applies as published.
St Julien A	350–450 cm source Sourced guidancehigh confidence Royal Horticultural Society: Plum rootstocks Checked 2026-08-13	Jubilee is of average vigour, so the rootstock's range applies as published.
