Opal Plum Trees

Opal Plum Trees

Opal plums are deliciously sweet, bite-sized dessert plums with a great colour range, from sunshine yellow to deep purple, often on the same fruit. They have pale yellow flesh with a signature Greengage flavour. Opal plums are really early cropping plum trees and in a good year you can look forward to the first fruit being ready at the end of July.  Because they are so early, Opal plums mature quite fast and so do better in the South of England; they also reward being planted in a south facing spot - trained against a south facing wall is ideal.

Opal's History and Parentage

Sweden may not seem like an obvious place for fruit trees to be studied and bred. In fact, the climate in the south is perfect for breeding hardy plants that will succeed in Northern Europe and Opal is just one of the creations of the Horticultural Research Stations in Alnarp and Balsgard, near Sweden's southern tip. It was crossed in the 1920's from two classic plum trees, Early Favourite and Oullins Gage, which are robust English and very tasty French cultivars respectively.

Plum Tree Pollination guide for Opal Prunus domestica

Your Opal plum tree is self-fertile, which means that although a pollination partner such as Marjories Seedling can improve the quality of the harvest, Opal is quite happy to bear a heavy crop all by itself. It is also reassuringly regular in the size of harvest each year.

Plum trees are natives of a warmer climate and need some special consideration to encourage strong growth, resistance to disease and bumper crops. Our section about plums in Fruit Tree Planting & Care will help you to give your tree an easy time here, which means more plums for you!

Please note that our bushes are on St Julien A rootstocks while our maidens are on Pixy rootstocks which we believe is preferable if you want to train a fan or espalier.
