Originally named in Greek, Anthuriums have a lot of names such as Flamingo Flower, Boy Flower, Painted Tongue and Painter’s Palette because of their flamboyant shape and color.

Anthuriums may become harmful, as the plants contain calcium oxalate crystals which may lead to severe mouth pain if eaten. But for being poisoned, you must eat large amounts of anthuriums. Besides, these plants may cause eye and skin irritation if our body parts contact with their sap. These bad influences will cease in time, but additionally cool liquids and pain pills may help you to recover.

Despite their poisonous influences, Anthurium plants symbolize ”hospitality” with their open, heart-shaped flowers.
