Washingtonia Robusta (Mexican Fan Palm) is a beautiful palm to grow. It's probably the most majestic palm tree around reaching heights of about 100ft. Hardy down to zone 8b (15°F or -9.4°C) this extremely fast growing palm can provide you with the best tropical look you could ever ask for.

The Red Delicious apple tree is a great plant to grow. It has beautiful lush foliage and can be very rewarding. I see nothing about it being a hybrid anywhere on the web so I can assume logically that the tree will bear fruit. This plant can grow in very cold climates, specifically in zones 3 to 8. It blooms in late May, starts producing in late June to August with a final harvest in September. It's fruit is very sweet when picked straight off the tree, and just one of these apples a day can keep you very healthy, although good luck stopping at one. ;-)
