Desert Smoke Tree, the Tree with a Wild Form

© Jared R. Shortman

To propogate plants seeds can be gathered in good numbers just beneath the plant which is often protected by low branches. Seeds can be infected by bruchid seed weevils (Acanthoscelides daleae a bruchidae). Scarification (physical or chemical) will make germination more even though it is not necessary. Sandy soil is preferred for germination and first stages of the plants life. I gallon pots are preferred. Smaller containers may restrict root growth. Mounding the soil in the container (with the seed planted in the top of the mound) will prevent problems with the base of the plant rotting. Germination is rapid (usually within a week), although a small percentage of seeds seem to take longer. Stem cutting root at a low percentage. Sow seeds two to three times their diameter (shallower sowing has caused seedlings to push themselves out of the potting media).

This is an unusual tree that has received little attention though deserving of more. It is also a tree that takes on a form not familiar in the temperate landscapes where many landscape design ideas have originated. It is being considered for commercial exploitation as an arid land crop. It has a lot of economic potential. The calyx and pericarp of the seed pod have potential as a source of aromatic resins for the cosmetics industry. Seeds contain Triglyceride oil with a unique fatty acid profile having potential as a cosmetic or specialty food item but being limited by low percentage oil (3-4%). Wood is close-grained and suitable for fire wood with aromatic smoke although in its geographical range, there are more suitable trees for burning.

Because it is a desert tree that shows economic potential it is of interest to those wishing to introduce new economic crops for arid lands. Because it fixes nitrogen, it is a suitable candidate for intercropping with other arid land crops because plants closeby benefit from the extra nitrogen in the ground.

As a landscape plant Smoke tree makes a large shrub or small tree with an unusual look, suitable for desert landscapes. It is a good soil stablizer, especially in difficult sandy soils, and can make a good wind break.
