Denniston's Superb plum trees

Prunus domestica
Denniston's Superb is listed in the RHS Plants for Pollinators

The small round green fruits of Denniston's Superb look like typical green gages, and have the rich gage-like flavor. However, illustrating how ill-defined the boundary between European plum and gage is, it is now generally considered to be a true European plum, on the basis of its upright growth habit and generally reliable productivity.

These niceties need not both the gardener - if you want a green gage without the fussy demands of some other green gages, this is the one to choose.

Denniston's Superb also has particularly attractive blossom, with larger flowers than most other plum trees.

Rated by the Victorian writer Hogg as "a first-rate dessert plum".

How to grow

Although the round green fruit resembles a green gage, Denniston's Superb grows more like a plum tree - upright, quite vigorously, and with good disease resistance. The long whippy branches soon adopt a weeping habit when loaded with fruit.

Denniston's Superb produces a lot of pollen over a long period in the earlier part of the plum blossom season, and is therefore an excellent pollinator for other early and mid-season flowering plum varieties.
