Pitcher Plants GENUS
Sarracenia
Sarracenia purpurea ssp.
venosa
This species S. purpurea has by far the widest distribution
of all eastern North American pitcher plants, extending its territory all the
way north into a large part of Canada. The species has well-recognized
subspecies: S. purpurea ssp. venosa in the southern range and S. purpurea ssp.
purpurea in the north, which covers the majority of the entire distribution. The
plants produce decumbent, bulbous pitcher leaves no longer than a foot. The
pitcher color ranges from deep red to light green. A short, xxxx pitcher has a
lid growing vertically with an undulating margin. The lid offers little
protection from falling rain water, and the pitchers are often seen filled with
water to the rim in nature. Flowering starts in mid-March in the southern range.
Short flower scapes (up to 30 cm) support a single, dangling flower.
Wavy hood margins of the plant with deep red coloration. White,
downward-pointing hairs on the inner surface of the hood are clearly visible.

within the pitcher tube. A vertical wall of wavy hood grows into the blue sky.
Numerous, short, downward-pointing hairs cover the inner surface of the
red-veined hood where nectar is offered for visiting insects. One precareless
step leads to a dire consequence for a xxx diner.

purpurea pitcher. Compared with other taller species of pitcher plants, the
low-lying posture of the pitcher of S. purpurea tends to attract crawling
creatures such as ants.
