酒瓶蘭（學名：Beaucarnea recurvata）在園藝中很常見，屬天門冬科，原產於墨西哥。半耐寒性常綠小喬木，莖幹直立，成株可高達數公尺。下部肥大，狀似酒瓶，因而得名。

肥大圓幹莖具有厚木栓層樹皮，老株表皮粗糙龜裂，狀似龜甲，為其特色，地下根為肉質狀。葉綠色，密集叢生於枝幹頂部，無柄平滑革質單葉，線形軟垂狀，質薄而硬，葉端漸尖，具細鋸齒緣。花小色白，生於葉腋間而頂生呈傘房花序，在夏季全日照下成熟植株才會開花，子房3室而缺花柱，有3柱頭。果實稍扁平，3室含有1-3個種子。

酒瓶蘭生命力強，幼株適合盆栽，可移至室內觀賞，成株適合庭植。性喜高溫，生長適溫攝氏16-30度，但在0℃以上均能越冬。全日照、半日照均可。因下端膨大的莖幹能儲存水分，故頗耐乾旱。栽培土質以肥沃之砂質壤土最佳，排水需良好以免造成根部腐爛。繁殖多採用播種法，春至秋季為適期；亦可使用母株上自然萌發的側枝作插穗以扦插法繁殖。經常修剪老葉，可促進植株成長。

Beaucarnea recurvata (elephant's foot, ponytail palm) is a species of plant in the family Asparagaceae, native to the states of Tamaulipas, Veracruz and San Luis Potosí in eastern Mexico.^[2] Despite its common name, it is not closely related to the true palms (Arecaceae). It was discovered in Mexico by a Frenchman in 1870, becoming popular in Europe and worldwide as an ornamental plant. There are 350-year-old Beaucarneas registered in Mexico.^[3]

It is an evergreen perennial growing to 15 feet 6 inches (4.72 m) with a noticeable expanded caudex, for the purpose of storing water inside. The single palm-like stem produces terminal tufts of strap-shaped, recurved leathery leaves, sometimes hair lock-shaped in the ends, and with occasional panicles of small white flowers once the plant reaches over 10 years of age. There are 10 different species of this plant, according to the Institute of Ecology in Xalapa, state of Veracruz, which runs the Jardín Botánico Francisco Javier Clavijerobotanical garden, where over 400 Beaucarneas are exhibited and more are grown in greenhouses for conservation purposes, in the "Colección Nacional de Beaucarneas" (Beaucarneas National Collection). ^[4]

B. recurvata is often grown as a houseplant or outdoor plant in temperate climate gardens. It is hardy to −5 °C (23 °F), and grows in full sun to light shade. It needs a proper soil mix to drain when watered, and must never be over-watered or mudded, as this will foster pests like the mealybug and cochineal insect. It cannot resist cold temperatures so it must be an indoor plant in countries with strong winters. When repotted it must keep all its roots. To maintain its original shape, the ends of its leaves should not be snipped. It is very slow-growing and drought-tolerant. It has gained the Royal Horticultural Society's Award of Garden Merit.^[5]
