Cultivation
editParkinsonia praecox is valued as a xeriscaping ornamental for its yellow wands of early-blooming flowers, its chartreuse-to-green bark, and its graceful branching habit.[3][4] A drought-adapted species, it drops its leaves in the dry season.[3][4] Overwatering will cause it to grow rapidly with weak wood, and then it is likely to collapse.[3]
