Cobra Plants with Spiders
2006 - May - 21,22,23
I visited a cobra plant habitat in
northern California. It was raining when I got there. But as
you can imagine, dangling flowers of Darlingtonia are well protected
from rain drops.

The new leaves sprouting out at
the time of flowering in cobra plant habitat. In a month of so,
the leaves develop into a functional pitcher.
Based on my past observations, I
always assumed the height of the flower to be around 70-80 cm at the
time of flowering. When the seeds mature in autumn, the flower stem
reaches 1 m. Some of my recent observations show, however, the scapes
are much shorter, say, only 30-40 cm. I have seen other people's
reports indicating similar scape length. My first thought was that
the length may differ depending on the year (due to severity of the
previous winter and the like). But I did find some remnants of previous
years scapes that are 1 m or longer. Now I think I know the reason why I
am seeing the shorter scapes in recent years: I am observing the flowers
earlier in the season (early May, as opposed to the end of May). I
believe the scape lengthens significantly during this period. I can tell
by looking at the density of bracts at the tip of the scape, just above
the flower. When the flower has freshly opened, the portion of the scape
close to the flower (a few inches) are not fully grown, as seen by a
short distance between neighboring bracts.
