yep. i'm a little late on this one, but that stuff will propogate VERY nicely from cuttings, and you can probably find a lot of sections to cut from that have roots shooting out already. i have the stuff in my azureus tank and it's growing like mad, with roots jetting out all over the place. have fun!
yeah, i've been meaning to take a couple new pics of it. added some wild moss (and lots of creepy crawlies that rode in on that stuff! ;-) ) and, as you guessed, the fig and lemon button fern have really taken off.
kinka of topic but i just thought it was kool, willow trees have some sort of feramone that stimulates plants to grow very quickly, i use it to keep my pyrocantha growing for my wandering leaf bugs to eat, but i plan to use it in my propagation tank
