Nearly everyone is familiar with the Venus flytrap, the famed carnivorous plant of the southeast that snaps shut on insects that might end up within its mouth-like leaves.
Many folks don’t know that its equally-carnivorous but much less dramatic
cousin, the pitcher plant, can be found in Western New York.
It just so happens that summer is a great time to find this rare plant. Its
large, brick-red nodding flower will be in full bloom, alerting you to the
pitcher below.
Those bladder-like leaves that give the plant its name are a vessel which collects water, and ultimately, insects on which it feeds.
It’s an evolutionary tool made out of necessity; pitcher plants grow in bogs,
mossy acidic wetlands like Moss Lake (near Rushford Lake).
In a bog, decay happens at incredibly slow rates. As an example, some happy
archeologists have found human bodies that were essentially mummified in
European bogs, well-preserved hundreds of years after their death. Because of
that slow rot, there is very little nitrogen available for flowering plants,
hence bogs being home to mostly mosses. Flowering plants that do remain need to
find nitrogen by alternative methods.
This is where the pitcher plant’s strange-looking anatomy comes into play.
Whereas the Venus flytrap appears to be a quick eater, the pitcher plant takes
its sweet time through an elaborate process.
The leathery, green sometimes burgundy leaves, with deep-red veins, which make
it look like a bodily organ, have pools of water within them. The stench of
that stagnant water and the death within draws flies and other carrion-eating
insects into the bladder. The downward facing hairs within the pitcher do not
allow the insects to fly or crawl out. Those hairs are said to issue a
narcotic, which stuns the insects that then fall into the water. Bacteria in
the water break down the drowned insects and the pitcher plant emits an enzyme
that converts the insect mush into nitrogen that the plant consumes through the
walls of the leaves.
It sounds like a lot of work, and it takes a lot of time, that is if the plant
is lucky enough to catch some insects. All of that, in conjunction with the
rarity of bogs, makes the pitcher plant one of the least common plants in
Western New York. It has a precarious diet while living in a precarious
habitat.
That has led New York State environmental officials to count the pitcher plant
as an exploitably vulnerable native plant, a classification teetering on threatened.
So, if you see one, do not pick it, even if you count yourself as a skilled
terrarium gardener. Not only is their harvest strictly prohibited on public
land, but doing so also compromises the long-term population of one of our more
interesting plants.
