The Alluaudia procera is indigenous to southern and southwestern Madagascar (Toliara). It is a spiny and scarcely branched (occasionally columnar), small succulent tree. This species follows an upright habit similar to Euphorbia milii ("Crown of Thorns"). Flowers take on a pretty yellowish-white color, forming crowded clusters at the end of branches. Outdoors, full sun exposure is required. Happily, this species can be grown as a houseplant as long as it is provided with high interior lighting. Utilize a well-draining soil mix.

Suitable for xeriscaping, this species is a terrific choice for those residing in hot, dry regions. A conversation piece, the unique and odd form of this plant is sure to earn a double take at your next barbeque. Although the Alluaudia procera can absolutely stand alone, it makes an interesting garden, fascinating. This is especially true when plants are grown in multiples, creating what looks like a miniature forest. Gratefully, the tough/sharp spines rarely pose a risk to passersby due to its upright habit.

In Madagascar, the bole (trunk), of the succulent is sawed into rough planks. This wood is locally known as "fantsilotra." It is used to construct houses, boxes, crates among other items.
