American author Sara Stein writes in her Noah's Garden that if Americans look along their own street, they will find a yew and a rhododendron in every garden. In the USA, many native plants have been excluded from the artificial Noah's Ark of the garden.
美國作家莎拉．史坦因在《生機花園》書中說，如果美國人看看自家那一條街的院落，植物除了紅豆杉，就是「外加一株杜鵑花」，在美國，許多原生的植物已被排除在人工花園的挪亞方舟之外了。
