I DO NOT have for trade:
Honeyvine Milkweed Ampelamus albidus
In Missouri, it is an INVASIVE WEED! I try to destroy this plant as fast as it pops up.
To see a photo of this plant, go to: http://ext.agn.uiuc.edu/wssa/subpages/weed/herbarium0.html
There are other invasive plant photos there as well.
It is amazing the number of different varieties of plants you can come up with when you do a search for morning glory using search engines. It is very true that common names in different parts of the country mean different plants.
I hope this clears up the confusion. I have added these links to my have list as well.
