Hopefully some of you may be able to help

I have three Sons Peter, David and Alden
In an effort to get them involved in the Garden, I am trying to buy
plants that they can 'adopt'

I have planted a row of Alders around our pond which is as close to
Alden as I am likely to get!

I have planted Acer Davidii and Davidia Involucrate for David

But can I find a Tree or for that matter anything called Peter, no
Anyone know of any plants with Peter in their name?
