We would like to know the differences between I. carnea and I. carnea ssp. fistulosa (Swamp Morning Glory) http://davesgarden.com/guides/pf/go/139641/ - no photos and not much info in Plant Files for I. carnea ssp. fistulosa). It is important for us to know the differences between I. carnea and I. carnea ssp. fistulosa because I. carnea ssp. fistulosa is prohibited as an exotic invasive noxious aquatic plant by both federal and Florida state law, whereas I. carnea is not regulated. I came across a JSTOR document that elucidates the differences between these two plants. I don't have JSTOR access on my computer, but our local library might have a JSTOR account whereby I can read the document. If anyone on this forum has JSTOR access and can provide any clearly discernable differences between the species and subspecies, or otherwise knows how to determine the differences, your input will be greatly appreciated. We are growing the Bush Morning Glory plants as terrestrial garden plants, so an easy determination might be that I. carnea ssp. fistulosa requiresa swampy or boggy environment while I. carnea can grow on dry land, but I don't know if there is such a simple method to tell the difference between the species and subspecies. Thanks greatly for any help you can provide! Jeremy |
