Fun Facts
- 🌱 Nandina Firepower's dramatic color change is temperature-dependent—the colder the winter, the more intensely red the foliage becomes, sometimes turning nearly black-red in very cold climates.
- 🌱 The plant is native to East Asia and has been cultivated in Japanese gardens for over 1,000 years; the name 'Nandina' comes from the Japanese name 'nanten,' which means 'southern heavens.'
- 🌱 Despite producing attractive berries, all parts of Nandina contain small amounts of cyanogenic compounds and are toxic to humans if ingested in quantity, though birds can safely consume them.
