Last week’s solution was pretty straightforward, but took research for most. We had six people as long entries, and their first names suggested tree varieties:

Bing Crosby -> BING Cherry (C)
Garry Trudeau -> GARRY Oak (O)
Jack Nicholson -> JACK Pine (P)
Jeffrey Wright -> JEFFREY Pine (P)
Dutch Schultz -> DUTCH Elm (E)
Dawn French -> DAWN Redwood (R)
The first letters of the tree types spell out COPPER, which is a type of BEECH tree. (It is also apparently a type of birch, so that was an acceptable alternate answer.)
I’m not ready with a new puzzle right now; I’ve got a grid filled, but not yet clued. I have some work to do this afternoon but I will get it out soon, hopefully.
