The Carnivorous Plant FAQ Field Trip Report -

Okefenokee and Doerun Georgia in 2003.

Return to the Trip Overview

Color variations:
In contrast, these giant plants were deeply flushed red on the tops of the pitchers. After five days, Beth and I saw more specimens of this plant than we could ever possibly count. By the fifth day, we had concluded that the main dimensions of color variation were the following:
1)Degree of red flush on the top 1/2 of the pitcher.
2)Presence/absence of copper color on top 1/3 of pitchers (visible only in the plants without red flushes, of course).
3)Pitcher lip--red or green.
4)Underside of pitcher lid--green or pale, vs. deep red or orange.

It will take another trip for us to decide if these variables are independent. For example, while we saw red-flushed plants with both green and red pitcher lips, we were not sure we saw plants of every possible configuration. We did not notice any truly anthocyanin-free plants, although we could have canoed right past them.

It was a real eye-opener to me to see all the different kinds of plants--I did not know there were so many color variations of this variety.
