Laxton's Superb is a classic English dessert apple from the Victorian era, still widely grown in gardens and small orchards in England. The apples have the orange/red flush which is characteristic of many English apple varieties.
The flavor is basically sweet, and the flesh is firm rather than crunchy. All in all, a typical Victorian apple.
One of the parents of Laxton's Superb is Cox's Orange Pippin, and it is often grown in England as a Cox-substitute. The appearance and flavor are quite close to Cox's Orange Pippin but the tree is hardier and better-cropping.
