Hello,

I have heard and read the expression "trash tree", but I don't know
what it means. If some trees are going to be offensive to my
neighbors, I want to know before I plant it! (And it's not as simple
as just asking my neighbors before buying. Lots of people don't know,
for example, what a blackgum, buckeye, or Euonymus is.)

So,
(1) What does the expression "trash tree" mean?
(2) How/where do I find out, before buying and planting, whether
species XYZ is a trash tree?

Thank you very much!
