I have about 200' of frontage along a road at the back of my property that I would like to plant a row of trees along. My mother-in-law bought my wife an Oklahoma Redbud (5 gallon?) for her birthday and we planted it today. Our idea is to plant a row of trees that will grow at similar sizes/rates that will grow along the back there and look good most of the year. I looked up this tree she bought us and it actually looks like it's going to be a great looking tree most of the year long which I'm excited about. Looking to see what other options I should be looking at; I don't want all the same tree. Some purple/pink/white/blue etc. I am in PA. Thank you.
