That looks too stiff for Yucca gigantea, maybe Dracaena draco, assuming those are seedheads in the image. This post was edited by saltcedar on Thu, Jan 9, 14 at 14:19

aas178- As I understand it, you have a chrome-brass piece that looks like it goes through the escutcheon plate, but is so short that not enough thread sticks out the backside of the plate to provide a non-leaking connection at the wall. Here is what I don't understand: It sounds like the company provided you this threaded piece; but why would they send you something that clearly doesn't work with their escutcheon plate?

I'm not sure if it's the lighting or not but it looks like it may be getting a bit too much water. The leaves may be displaying signs of oedema or edema (whatever you want to call it). Again, it could just be the lighting though.

I would suggest the same thing. Pics to compare: https://garden.org/plants/view/75389/Birds-Nest-Fern-Asplenium-nidus/
