The other plant is Lysimachia nummularia
Rivercats said:It will be okay till you get back but my suggestion is trim the bottom inch or so off the stems before planting.
Neither one of the plants had roots....it was as if someone cut them off. Is this normal?
Not only is it normal but as the stems grow and get too tall cut them off to the height you desire them to be and replant the cut off tops. This is a cheap and easy way to propagate your plants.
Whoa. sounds nice. Plants can be expensive :/
If your water wisteria does not do well planted, float them. They will send their roots down into the water column, which looks kind of cool, IMO.

Are they losing color or melting? You said they came in as cuttings without roots and often time have to go through an adjustment period while developing roots. If you have multiple stems you need to seperate them and plant each stem individually. If your light is too low this could be an issue. What you can do is float the stems as mentioned above until they develop roots then try replanting them. Also you need to use a good liquid fertilizer once or twice a week as wisteria draws almost all it's nutrients from the water.
