Habitat:
Marshy
areas are its best known habitat. |

Description:
The
leaves range from 4 to 12 inches long, narrow at the base giving way
to a bulbous middle which constricts at the top to form a narrow opening.
Above the opening, the leaf widens to form a somewhat horseshoe
or heart shaped surface, which is generally ruffled around the edges.
The upper surface of the leaf is covered by hundreds of downward pointing
hairs which direct the prey into the pitcher.
The prey is usually attracted by nectar which is produced at
the lip of the narrow section of the trap. The prey may also be attracted
by the color of the plant. Once the prey is inside, the plant absorbs its nutrients through
digestive glands at the bottom of the pitcher.
The
flowers are borne on 12 to 16 inch stalks which generally appear early
in the spring before the new leaves begin to appear. As with
all Sarracenia, the corolla is made up of 5 oval, very large petals,
sunk inwards at the ends which are numerous stamens, each composed
of a short filament terminating in a simple rounded anther.
The ovary is almost spherical and is surmounted by a short cylindrical
style, self topped by a shield in the shape of a five-cornered umbrella
covering the stamens. Underneath the ends of each of these corners
is a stigma. The fruit is a capsule of five compartments,
which hold the tiny seeds. When the seed matures it should
be collected, dried and stored through the winter. In
the spring sew them directly on wet peat, maintain high humidity and
temperature of at least 60 degrees.

Cultivation:
The plants prefer an acidic medium such as sphagnum or peat moss,
but will tolerate alkaline soils.
The soil must be kept moist at all times during the growing period.
Reduce the amount of water in the winter months, but do not allow
the soil to dry out. Rain
water should be used if possible.
If you must use chlorinated water, allow it to sit out for 48
hours before use. Plants
are usually difficult to grow indoors
because they require large amounts of sunlight, which gives them
their desirable red color. |

Prey:
The pitcher plant’s prey is generally flying insects, flies, bees and
wasps.

Pest and Diseases:
Aphids and Fungi are the two
major problems associated with Sarracenia purpurea.
Any insect problem can be eliminated by treatment with Orthene,
a product of Ortho, which can be purchased through your local garden
center. Fungi problems
can be eliminated by treating the plant with Daconil
2787.
In the U.S., these Sarracenia are attacked by the caterpillars
of three species of butterfly of the Exyra genus.
The caterpillar bores into the tuberous portion of the plant,
eating it from the inside out. |
