Columnar Apples

I forgot to mention this cool little apple tree. Perfect for apartment (and boat!) dwellers who love apples.
"Now you can grow delicious, full-sized apples in a sunny corner of the garden or in a pot on your patio. These special vertical varieties grow up to 10' tall, but their branches don't spread. With minimal pruning, you can maintain their slim profile and keep fruit in easy reach. We ship one Northpole™ and one Golden Sentinel™ to ensure good pollination."
