棒棰樹屬多肉質落葉小喬木，原產馬達加斯加島。高可達1~5m，有木質化地下莖。圓柱形莖幹直立，綠褐色，分枝棒狀，莖上散生3刺一簇的長刺。單葉簇生於莖端如傘狀，葉闊線形，先端銳尖狀，葉全緣，革質，葉面深綠色，葉背淡綠色。花白色。

A succulent deciduous small tree in the genus Pachypodium, native to Madagascar. It can reach 1~5m in height and has a lignified underground stem. Cylindrical stems are erect and greenish brown. The branches are rod-like, scattered clusters consisting of 3 long spines grown on the stems. Single leaves clustered at the stem end like an umbrella, leaves broadly linear, apex acute, entire leaves margin, leathery, blade dark green, pale green leaf underside. Flowers white.

栽培：全日照環境下可生長良好，室內僅能短期放置欣賞，久放會有徒長現象，種植時選擇排水透氣的介質。夏季炎熱時或有落葉休眠現象，可減少澆水頻度以助越夏。

The plant enjoys full-sun environments. Indoor plantation can only last for a short period of time and very likely grow water sprouts if kept indoors for too long. The plant is likely deciduous and dormant in hot summer, reducing the frequency of watering will help the plant to survive summer.

造型特異，幼樹是迷你盆栽的材料，常單植或作為多肉植物組合盆栽的主角。中、大樹多用於大盆缽單植或庭園造景，因樹幹密佈銳刺，應用時需避開人可觸及的位置。

The plant shape is unique. The seedling is a material of mini pots, often single planted or used as a feature in succulent combination pots. The medium and large-sized trees of the plant are mostly planted in large single pots or for garden landscaping. Because of the trunk is covered with densely sharp spines, it is advised to plant in places unreachable by people.
