The Valdosta Tree Commission is offering Chaste trees
“to citizens at wholesale prices with the hopes of planting 100 trees in the city limits”, but this may actually be a bad idea, since this

“has no serious pest problems and attract butterflies to the garden.”

That first phrase is a red flag after reading

So what to plant instead?
