I know there are several vines called this, but I don't know the scientific name for the one I have. All I know is that is grows on the roadsides around here, and blooms such lovely fragrant white blooms. Very pretty. I would like to propagate this plant so I collected the seed in late fall and am now storing it in an airtight container in the refrigerator. I left the plumes on the seed. I have no idea on how to go about planting the seed. Any help would be greatly appreciated.
