They are almost certainly some time of fruit tree shoots but won't be Stella and won't make very good fruit.

I used to live in Tennessee and tried growing them there and didn't have any luck. I moved back to Indiana in 04 and live in the northern part of the sate. Have had some limited success here as they seem to like the cooler climates better. I do go to Eau Claire, MI every year to pick them, both the sweets and sours. the big thing I have found out about growing cherries is they seem to be more prone to diseases, pests, and weather. So far I have had only one year and that was last year (2013) that I got a small crop of cherries from my trees. My sour cherries (North Star and Montmorency) seem to be a little more hardy than the sweets (2 Rainer, Lapins, and a Windsor). Just my opinion and would like to see what others have to say about your post! This year with the harsh hard winter I didn't get any blooms, and then in their weakened state the aphids hit my sweet cherry trees and done some damage.

Tracy, I think you'll find plenty of information and opinions in the threads shown in the link below. It's the results from searching for 'dwarf spacing' in this forum (which should cover dwarf and semi-dwarf varieties). As you'll see, a big factor in spacing will be pruning. The cedars may present a problem from CAR (cedar apple rust). Since I'm not familiar with the prevalence of this disease in your area (and can't even tell where you live because you didn't include that info with your zone info or on your member page) , you might want to contact your local ag extension service for more locally-relevant information on that. If you want to supply your location, you might be able to get more information about CAR here, from someone close to your area. You may also want to do a search from pruning techniques. You'll find numerous threads on the topic (maybe to the point of overload). Once you've done a little studying on that, come back and ask questions to clear up any concerns you still have. I wish we had one single, really thorough thread about pruning, but unfortunately the information is pretty scattered. Finally, have you researched varieties that will do well in your area? That may be a "can of worms". If not, your local extension agent might be able to give you some initial ideas on that too, but you'll definitely want to supplement his/her recommendations with your own research. Here is a link that might be useful: Search for 'dwarf spacing'

The Meiwa is not going to get large as a standard. The Powell and the Cara Cara will naturally be large so using a Semi-Dwarfing rootstock will help keep them manageable. The Moro will get almost as big. My preference for those would be C-35 and prune to keep them about 8-10' tall and wide. A Standard Meyer at a friends house was planted 25 years ago and is about 10' tall but tries to be wider than that. I planted standards as I was concerned that anything smaller would not grow big enough to espalier against a 6' block wall. I can't imagine using Flying Dragon for anything as it will grow so slowly, you will need to wait many years to see much growth. Many of these varieties have compatibility issues with different rootstocks so thinking that you are going to decide on the best one and then use it on all varieties will not work out well in the long run. You need to talk to a grower that knows the requirements for you area. What originally was called Dwarf was gradually mostly called Semi-Dwarf as you are not really limiting the eventual size of the tree as mostly picking a slower growing tree. Dwarfs are also trimmed more into a bush shape that I don't find looking right. A Meyer trimmed as a Semi-Dwarf Bush shape will natrually want to be 15' wide and 5' tall.
