Moss Suggestions

[Jbram]

I would like to find some moss to attach to a couple rocks in my tank but I am not sure what will work the best.  I am not a fan of java moss as it just seems to take over and encroach on everything.  I have seen small patches of flame moss which looks good I am just not sure how fast of a grower it is and if will present any problems.
 
Any other suggestions would be most welcome.

Weeping and Christmas moss are lovely, as is flame.
 
Java is good for a wild look, but isn't all that structured, as you've noticed.
