Alluaudia dumosa is a beautiful, drought-tolerant large shrub or small tree native to Madagascar. It can grow up to 5-10 feet in height, with a wide spreading habit, and has thorns or spines that gives it a wild, exotic look. The tubular leafless branches are thick and white, with a fine gray powdery coating. The bark is gray and the flowers are white and fragrant.
Though Alluaudia dumosa can be grown in partial shade or semi-shade, it does best in a full sun position with adequate ventilation. It is moderately drought-tolerant and requires regular enough sunlight for attractive flowering. It needs regular watering when growing in warm climates but requires only moderate water in most other climates. It does best in USDA Zone 9-11.
For those living in colder areas, it is possible to grow this plant successfully in a pot. Make sure the pot is sufficiently large with adequate drainage. Potted Alluaudia dumosa should be watered only when the soil has dried out. It should be allowed to rest in winter and in cold conditions, but, if the root ball dries out, the plant should be reprimed with water to prevent damage. Place the plant in a light, warm location and in bright indirect light but avoid direct sun as this can cause scorching of the foliage. Keep the plant near a south or southeast facing window to get the most of the sun's rays during the day.
With proper care, Alluaudia dumosa will leave you with a beautiful, lush addition to your garden.
