The Anthurium genus contains about 1000 species—the largest genus in the arum family—but only two of them are grown for their bright red spathes. This is Anthurium andraeanum, a native to Colombia, Ecuador, Venezuelan Antilles, and the Windward Islands. Common names include flamingo lily and painter’s palette, although I’ve only ever known it simply as Anthurium. Like many plants in the Araceae family, Anthurium species contain calcium oxalate crystals (CaC2O4(H2O)x) and are therefore poisonous to humans. They’re pretty, though.
