Menyanthes trifoliata, Bogbean. Here is a link that might be useful: Bogbean

Elaeagnus is on the invasive plant list in many states.....Texas, for example. It's a good idea to do a quick search to see if this plant is on that list in your state. If you've ever helped conduct a parkland cleanup of invasive thugs in your community, you'd never want to contribute to the problem. My suggestion is that you remove the plants, not only for their potential to cause ecological damage but because they are so unsuitable as a landscape ornamental.

If you have an eye for it, could get some differences. Most if not all may be in the flowers. Very top picture, top plant looks to be Huernia, bottom right looks to be Orbea, Looks like a Sansevieria Gold Hahnii in bottom half of top picture. I would pot them all up in a fast draining mix in small pots (2"). Them place them in a 10 gallon fish tank to keep moisture high but soil on dryer side. Spray with a 0.1 mix of Hydrogen Peroxide in a spray bottle. That's about one table spoon to 2 cup bottle. Keep in a warm spot with a bright fluorescent light on it 12 hrs. a day. Come spring you could plant up in larger containers. Would I love to come across something like this. Please keep us posted. I would love to see what all you got. Stush

Thanks! I now think so too. I will be moving it to a hanging planter in a much sunnier area, thanks to you. :)
