Absolutely agree about Spartan, I also have a Greensleeves, an Egremont Russet, an Elstar and a Sunset. I'm in a dilemma about a Discovery tree which was here when we moved in. The apples don't keep, and the fruit is insipid in flavour, quickly becoming spongy and dry. The only thing it has going for it is the beautiful mass of blossom in spring, which my bees love. I'm loath to take out a healthy tree, but the fruit is such a disappointment.
