Datura. Its a type of moon flower. Hummingbirds love them. After teh flowers , there will be a spikey ball that grows. Inside that ball are seeds. I usually cut and save teh balls in a paper bag untill it is completely dried. Then wearing leather gloves-cut it open adn save teh seeds. Be very careful, as teh seed pods are very prickly. It isworth the effort as they get huge beautiful flowers tht open at nite.
