Nandinas are the perfect landscape plant for beginners or experienced gardeners. Heavenly Bamboo Nandina â A virtual rainbow of red-tinted colors in one sun-loving shrub that is semi-evergreen. Fire Power Nandina â This is a compact shrub of contrasts.
It has another problem, though. Nandina berries contain a toxin called cyanide. Birds in the US haven't figured out how to deal with the poison, and some cedar waxwing birds have died from eating lots of the berries. The berries can be toxic to any other animal too, so don't eat them.
