When we bought our home 20 yrs ago, there were some planted. Something happened and they never came back. I have looked and looked for some of the prickly seed pods and cannot ever find any! We used to sit out at night & watch the lg moths flock to them. At first I thought it was Hummingbirds. LOL They are just stunning IMHO and I too loved the smell. Anyone have any seeds they would share?
