I bought an assorted plant package once and this plant was one of the few that did okay. It had a long stem, but I laid it down sideways and covered it with substrate, and it came up more of this bush appearing plant. It was just kind of hanging in there with a few others I had, but when I got more diligent about my liquid fertilizer usage as well as turning the light down, it really took off. When I had the light high, it had a reddish tinge on the topmost leaves, but now it's more green. Any ideas what it is? I have looked in all the profiles and can't ID it.
