But take an objective look at sumac shrubs this fall, and ask yourself the question, "What other shrubs have fall foliage to match this?" I know what my answer would be: "Other than burning bush shrubs, not many!"
For those in eastern North America who wish to avoid planting burning bush shrubs -- because they are alien invasive plants -- sumac shrubs may be your best option. Sumac shrubs are somewhat invasive, too; but at least they're native.
