White purposeful residue on Palms and Tropicals?

Could someone tell me what that white sandy-like residue is that is spattered on most tropicals in garden centers? I've noticed Mandevilla, palms, jasmines, oleanders and more at several nurseries with this same residue. Is it some sort of lime from well water, wilt-proof agent, fungicide used in the nursery trade? It washes right off. Thanks!
