'Rubinstar' apples are a lovely, rich maroon colour, occasionally splashed of with yellow, and being related to 'Jonagold' they are big and fabulously juicy with a deliciously sweet flavour and a crisp crunch. A versatile apple, they are gorgeously tasty picked straight from the tree and also ideal for cooking, making tasty desserts. 'Rubinstar' is a mutation of 'Jonagold' and is a 'triploid' variety, meaning that it has three sets of chromosomes instead of the usual two. Triploid varieties are sterile, so they can't pollinate themselves or other apple trees. They need other trees nearby to pollinate them, not an issue if you grow more than one apple in your garden, or if a nearby neighbour does! Supplied as an established tree, 150cm (5ft) tall grown on an M9 dwarfing rootstock in a 24cm pot, growing to a height, and spread of 2.5m (8ft).
