Looking for tree advice
We built a new home in zone 5b about 2 years ago. We put in sod and are looking to add a few trees to the back yard. We already have a crab apple and another tree that I forget the name of (see pic). My DW asked me to pic up some magnolias from the local Lowes the other day as they were on sale. I went to pick them up and found out that they were Jane Magnolias, which are more bushes than actual trees. Which she doesn't want. I spent the rest of the day driving around to various local nurseries only to find that they didn't really have what we wanted. I found a nursery a good 90 minute drive from here that has the trees that she would like, but they are asking more than we have budgeted.
Which got me thinking that I may be making this more difficult than I need to. So here is my dilemma. Part of our lawn borders a 100 foot section of sidewalk. That sidewalk connects our subdivision with a public walking path.
We live in zone 5b and are looking for maybe 3-4 trees that we could plant 10-20 feet off the sidewalk. Our goals are to provide some shade in our yard and flowers in the spring. We want trees that are hardy and that will grow quickly enough that we don't have to stoop forever to mow underneath them.
We are willing to purchase smaller trees now and wait a few years to have them grow. I'd like to keep my budget less than $200 and I don't mind at all ordering the trees online.
Any suggestions from the group?
