Hi Kosta, this is tree tobacco. It comes up here after any rain, and grows very fast but usually it's dead before the rains in the next year. Spreads very quickly. Some consider it a weed but we know that in drylands anything that survives is a bonus. It is poisonous tho, leaves, stems,
roots, flowers, seeds, everything.
