Hello.

So I have a row of about a dozen pyramidal English oaks. I know over time they will get large. My issue is my neighbors are, ummm, difficult. They allow their lawn to grow knee high (and the weeds even taller!) this is Canada so there are no HOAs.

I am trying to screen their yard as much as possible. Even when the oaks eventually grow in, the 2-3’ underneath between trees will still be open. Any idea if there’s anything I can plant here?

I am zone 5. My yard is full sun south facing….the oaks are on the west side, so anything planted in front should still see sun for a good chunk of the day.

The space between the retaining wall and oaks is about 2’, and the oaks are planted either 8-10’ apart.

I’m wondering if there is a mounding shrub (flowering or not) that could go there…without looking odd?

Thanks in advance
