Desert Senna(Cassia armata)
Seeds of many desert plants do not sprout easily. Some need to be passed through the digestive tracts of animals before they grow. Some, like the Desert Senna, need to be soaked by a heavy rainfall and the scoured clean of its coated resin by the rocks in a wash.
If conditions are right, golden flowers will bloom in April and May but the plant will be leafless most of the year. The Desert Senna relies on green chlorophyll in its stems to manufacture food.
