how do plants reproduce

[Warr40]

I'm still confused on how plants spread i wanna know how java moss, java fern and horwort spread though-out the tank.
How long will it take for java moss and java fern to cover a 5 by 2 piece of driftwood
will java moss and fern latch on to the wood as it grows?
thanx

Some plants "reproduce" from seeds, but Javamoss just kind of spreads. Sometimes it grows really fast, other times it doesn't grow that fast, and yes it will just latch onto the wood.
