A few weeks ago I bought a little 6 pack of Celosias from a local nursery. I put a couple with some other plants and the bulk of them in their own little pot. These ones seem to be struggling. I read that they are very easy to grow and do well in most any type of soil as long as they get lots of sun. Which they have been.

One of the ones I put on it's own with some different flowers still looks pretty healthy, leaves are greenish and it seems to have rooted well. The ones in the photo here have all orange leaves (I think they should be greenish), haven't shown any signs at all of growth and they are all really wobbly (you can see I had to help them stay up with sticks). They just don't seem to be rooting well at all. They feel as if I could pull them right out of the pot no problem.

Are these guys goners or is there something I can do to turn them around and get them growing? Any help would be appreciated.
