Thanks everyone. It sounds like it should be treated a lot like the Lantana that I mentioned that I have at my old house. I'm not sure what variety it was, but that thing (actually several of them) was awesome. It grew big and full (probably nearly 5' across) with lots and lots of yellow blooms. In the winter, it would die to the ground leaving a nasty jungle torture device with lots of straight, pointy, woody twigs 3' long. In fact I just cut those back today to within a foot of the ground and the shoots were starting to appear at the ground. I'm sure, as always, they will grow back into beautiful, full plants in short order. That being said, I probably will cut these butterfly bushes back and see what I have there. Is it OK to go ahead and cut them back now? Thanks again for the advice!

As bboy said, 1 is a Portulacaria (I think probably Portulacaria afra). It is Elephant Bush, Elephant Food, and various other nicknames, and is sometimes called Dwarf Jade, but it is not truly a jade -- jades are in the Crassula genus, a different genus of succulents. [Though they resemble each other, Jade plants and Portulacaria afra are not in the same genus, not in the same family, and not even in the same order. They are distant cousins at best.] Here's some info about P. afra: http://www.smgrowers.com/products/plants/plantdisplay.asp?plant_id=1314

The first one looks like Nandina domestica.

there is a very active houseplant forum ... once you get all the names ... general observation ... a lot of non draining pots ... perhaps old media ... also.. have they always been this close to that big window ??? ... a few might look light deficient.. but they shouldnt be by this window ... ken
