Desert Senna

Desert senna can be seen growing along the highways and in the fields. It is very hardy and requires very little water. It can survive in the driest of climates. Occasion watering once a week will keep the flowers in bloom. It has a gray-green look and becomes woody with age. It gets about 1 1/2' tall with a 2' spread. Planting these in mass quantities gives you a very showy look in any rock garden.
