Clumps:
It looks like I missed the prime time
of the year for these pitchers, as most were crisping.
These plants are being very carefully monitored by many different
people. I could tell because just about every clump of plants had
monitoring markers--either flags, tape, or permanent rebar stakes.
You cannot see this in my pictures because I used clever little tricks
to hide all the flags, such as placing dead leaves etc. over all of
the markers. But those flags were everywhere.
