Merton Glory

An early white-fleshed cherry with very large fruit. Self-sterile, and its incompatibility group is not recorded here — pair it with a self-fertile cultivar, which sidesteps the unknown entirely.

A cultivar of Cherry. 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 Merton Glory, from the 7 cherry 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.

Cultivar	Verdict	Why
Lapins	compatible	Lapins is self-fertile and pollinates every other sweet cherry — its pollen is rejected by none of the S-allele groups. It will set Merton Glory even though that cultivar's own group is not recorded.
Stella	compatible	Stella is self-fertile and pollinates every other sweet cherry — its pollen is rejected by none of the S-allele groups. It will set Merton Glory even though that cultivar's own group is not recorded.
Summer Sun	compatible	Summer Sun is self-fertile and pollinates every other sweet cherry — its pollen is rejected by none of the S-allele groups. It will set Merton Glory even though that cultivar's own group is not recorded.
Sunburst	compatible	Sunburst is self-fertile and pollinates every other sweet cherry — its pollen is rejected by none of the S-allele groups. It will set Merton Glory even though that cultivar's own group is not recorded.

2 further cultivars return 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: Morello, Napoleon.

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
Gisela 5	250–350 cm source Sourced guidancehigh confidence Royal Horticultural Society: Cherry rootstocks Checked 2026-08-13	Merton Glory is a vigorous cultivar, so expect the upper end of this rootstock's range — though a dwarfing rootstock still keeps the tree small.
Colt	400–500 cm source Sourced guidancehigh confidence Royal Horticultural Society: Cherry rootstocks Checked 2026-08-13	Merton Glory is a vigorous cultivar, so expect the upper end of this range or beyond.
