Originating in southern Europe and Asia, this long-lived and slow-growing tree has proven to be well adapted to our deserts. The large palmate green leaves have a spicy fragrance, and drop in the fall. Large terminal spikes of indigo flowers set 'Montrose Purple' apart from variable seedlings. These fragrant flowers attract bees, butterflies and hummingbirds during the summer months. After blooming, narrow spikes of round, dark brown seeds are produced. Plant in full sun and provide moderate summer irrigation.
