I grow Magnolia "Susan" and if your space is limited then it is a good choice. It is very slow growing and I suspect it will take 20 years to reach 8ft at present rate of growth. Amelanchier will make a much quicker impact than the Susan, if that is important. Ultimate size will vary as ther are a number of different species, some reaching full size at 10 ft others going onto 30 ft, so ensure you choose the right one from a trustworthy source if going for the Amelanchier option.
