Hello!

I will greatly appreciate your help. I recently purchased two river birches. One a heritage the other a Dura Heat. Not exactly sure I know the difference between the two (leaves are different), they look similar, one currently is taller than the other. The Dura Heat was a lot cheaper than the Heritage, so I bought it as well.

My question relates to a landscaping design where a river birch heritage is to be planted near my deck in my back yard, about 10 feet away from the deck and about 6 or 7 away from the property line that divides my neighbor's property from mine. I love the tree, but not sure it would be wise to plant it there. Also, unsure about the heritage or the dura heat near the deck, not sure what is the difference in size. Will the Dura Heat get bigger than the Heritage? I also considered planting the second tree at the corner of my house in the front yard near a Sweetbay Magnolia currently planted about 6 or 7 feet from the corner and away from the Sweetbay. Would there be enough space and if so, will it look good with the sweetbay. I'm in zone 6. Trying to make this work..but feeling overwhelmed and confused. Please help!!
