We had those in Chicago. They called them snowballs. Now that I look closer, they are not the same. But close enough. I don't know if they grow here in Arizona, but I have not seen any. I can't find any. Oh well....
You might be thinking of Queen Ann's lace or wild carrot. They are all related and look similar but hogweed is 10 x the size.

I don't believe it is known in California. Let's keep it out.
Giant hogweed is native to Caucasia and has spread to Europe at large as well as parts of North America. Its sap is phototoxic, getting it on your skin makes your skin sensitive to UV light and can cause blistering.
