Very excited about Epipactis....still not sure if that is what it is though. I will wait till it blooms. From what I have googled it looks like it gets numerous buds, these only have one at the top. Thanks!

Can you provide a close up picture of the leaves? Also, you could cut open a fruit and see if it has a single seed (like a cherry does) or multiple small ones (like a crabapple, for instance).

Planting two of the same cultivar is equivalent to planting a single larger tree. If the cultivar is self-fertile (or partially self-fertile, as is the case with Gala) some fruit may be produced without the presence of a cross-pollenizer, but you will get much better results from an appropriate second cultivar. If there are crabapples or other apples in areas around your yard (like a vacant lot or in a neighbor's yard) that may also work to provide sufficient cross-pollination. Below is an example of an Apple Pollenizer Chart. Contrary to what its title claims, it does not discuss pollinators (bees, etc). Here is a link that might be useful: Random Example of an Apple Pollenizer Chart

all fruit trees need a certain amount of "chilling hours", an amount of hours where the temperature is between 34 and 42 degrees or something, each variety has its own set amount of chill hours required to have a chance of fruiting, w/o adequate chilling the internal parts of the flower will not form properly and pollination will not occur. There are very few drought tolerant fruit trees. you will have to water. locate your annual average chill hours then, do some research on varieties that meet those required hours. http://fruitsandnuts.ucdavis.edu/Weather_Services/chilling_accumulation_models/about_chilling_units/
