We all know that Sweden is famous for Volvo Cars, Abba and Ikea, but we must also add to that impressive list of achievements, breeding very good plums! Over the years plant breeders in Sweden have released a series of plum cultivars that are among the very best in the world and are grown across the globe. One of those varieties, Opal is probably the best know, and for very good reason indeed.
Bred in 1925, Opal has excelled; giving very large crops of delicious tasting fruits year after year after year. Those delicious fruits are a testament to the breeder who crossed the varieties Oullin’s Gage with Early Favourite. The wonderful, sweet flavour and melting flesh of Oullin’s has been passed onto Opal, but given the gage’s golden colour, we must look to Early Favourite for Opal’s red to purple colour and its early ripening.
Considering all of that background and pedigree, it is no surprise that plum growers and gardeners around the world continue to plant Opal after almost 100 years. A century is a very long time for most things and alludes most of us. For a fruit variety to still be at the top of its game and amongst the best in the world; it is just remarkable.
Early April sees a mass of snowy white blossoms, which set fruit very easily and quite quickly start to show the tiny fruitlets forming. By the middle of July, the fruits have swelled to the size of a hen’s egg, and in early August, the green coloured fruits start to turn to yellow with red blushes that face the sun. Hang on though - don’t pick them just yet!
Give them another few days until mid-August, when the fruits have turned a dark red bordering on a purple colour. Now pick them - and be quick about it before someone else sees them!
