Blossom: Sturmer Pippin

This one is something of a mystery. It was ordered as Spartan, but when it eventually produced fruit, the latter were hard, brownish green and almost impossible to ripen. More detailed examination of shape, eye, bowl etc do show features that all match with SP. Blossom dates seem to match those given for SP in the literature too.  I've now reduced the cordon to a couple of feet, and will graft a more useful variety on to the extension growth next year.
