Lets start off with some of my pictures of my drosera bog...
Pretty innocent,... right?

Underneath, it's a battle for survival: or as Darwin stated, survival of the fittest.

Roots, roots and more roots, The plants on the surface are FIGHTING for survival through the many plants... and several of them have adapted into 'Capensis Trees'.
See the inch or two of black 'bark' there?

It's like it's walking:

Here's my finger for reference, now look down at yours and tell me, that these Capensis are not trying to survive and outlive their opponents.

Even the lone Utric has to survive.

Heh, this is all my thoughts but I was just wondering if it was the buildup of dead material that cause capensis to do this, or if it's something else. I remember a year or two ago, there was discussion for 'Capensis Tree's and I just wanted to bring this back. It's surprising but these plants will be turning 2 years old in a month or two.
EDIT: Here are the little monsters before becoming invasive. Man, they WERE cute..
