Bottle Tree Moringa

From the spiny forests of southwestern Madagascar, the Moringa drouhardii puts up a smooth pale trunk that swells into a tapered bottle and then breaks into a fine, sparse, feathery crown. The effect is closer to sculpture than to a tree, and it is achieved on some of the driest, thinnest limestone ground on the island.
Where an arid scheme needs a vertical element that will not ask for irrigation, this is one of a very short list of candidates.
Bottle Tree Moringa brings sculptural height to a desert scheme without adding to its water demand.
