Hey Jay I am looking at putting some Utricularia Graminifloia in the foreground. Doesnt get tall but thats good with so much carpet.
I know a few club members have done the dry start to UG because it is a slow grower easier to establish that way as well then they flood. If I remember correctly it is a light demanding plant but I don't have much personal experience with it. Good Luck.
I too am looking into bucephalandra for some of it. I think it was the blue and purple.
The tough part is affording a large enough piece of buce to have an immediate impact or having the patience to grow it out.
