Ewing Blue is a large multi-purpose European plum that makes particularly good prunes. A reliable tree producing fruit of excellent quality.

The fruit

Ewing Blue is a European plum variety with a deep blue colour. The fruit are quite large with excellent flavour. Ewing Blue is a great plum for making prunes and is also very good for canning and fresh eating. Harvest is in early September and like most stone fruit it has a pretty limited fresh storage life.


The Plum Tree

Ewing Blue plum tree is a vigorous grower and reliable producer. It is hardy to zone 4.

Sadly, this varietyl has one major drawback. Like all European Plums, it is very susceptible to Black Knot: a major fungal disease which can affect the tree very badly. It is our last year propagating it, as it has proven itself too susceptible to disease. It produces really wonderful plums, so we are sorry to lose it, but we have chosen to concentrate from next year on more resistant varieties that are more in line with our philosophy of producing only trees that are hardy, resistant and easy to grow.

If you have noticed Black Knot in your area, we would not advise you to go for this plum tree as you will likely have some problems with it later on - however if you want to try it, now is your last chance!

It will need to be planted along with another european plum, such as Petite Soeur de la Mont-Royal.
