Sand:
The plants grew in almost pure sand. Unfortunately, I can't say I dug into the sand, so I don't know how deep it was. But as
I didn't see anything other than sand, I suspect it was pretty deep. Much of the sand was stained brown, yellow, or red with tannins
from the seeping water.
These plants were not quite as far along in growth as the plants at the first site.
The dead leaves, mired in the sand in swirling patterns, were almost psychedelic!
Here is a wider view of the same plants. In that photograph, see if you can
spot the Drosera capillaris almost completely submerged in the wet sand--only a few
red marks indicate the trap surfaces above the sand!
