Hi folks - new to the forum, and pretty new to gardening. I'm trying to find out what type of flower my neighbor has/had. It was a tall flower, shaped like a spikey white ball, sitting atop a long thick stalk, almost looking bamboo-like. About 3 feet tall. Imagine taking one of those big white 4th of July fireworks and popping it on a stick and you get the idea. Anyone? They have since dried out and I have seeds to plant, but know nothing about them and the neighbor's gone. Also, if anyone has any additional suggestions, like how to plant the seeds, maintenance, etc., that would be greatly appreciated. Thanks!
