Family:
Sarraceniaceae
Genus: Sarracenia
Common Name: Red-Topped Trumpet
Origin: Southeastern United States

|
|
Habitat:
This species is found in damp, even swampy locations, usually
in the presence of spaghnum moss.
It can be seen growing in fields among other short plants and
grasses. May be seen growing in side ditches or anywhere sufficient
moisture is present. It
may also occur in a woodland setting but this is rare because of its
light requirements. |

Description:
The leaves of Sarracenia rubra
are shaped like tubular trumpets, are erect with a hood covering.
The mature height may reach 3 feet.
These leaves grow from a rhizome which grows at the surface
of the soil. Each rhizome will produce 3 to 20 trumpet shaped leaves annually
then will grow winter leaves (phyllodes)
in the fall. When
grown in full sun, these leaves are thick and firm which makes them
fairly resistant to wind and rain.
The hood generally keeps the rain water from entering the trumpet,
so it will be less likely to fall over.
Sarracenia rubra is a
passive pitfall plant, it doesn’t have to move to capture its insects.
The insects are attracted by nectar produced by glands around
the outer edge of the hood and underneath the hood where it attaches
to the mouth of the trumpet.
Nectar is also produced around the rim of the trumpet and along
the wing formed where the two leaf-edges join.
Any escape for insects venturing inside is virtually impossible.
Victims have no alternative but to make their way downwards where
they end up being digested by enzymes and bacteria.
Most of the trumpet tubes will become completely full of insects
in the season of growth.
The flowers of the red-topped trumpet are bore in the springtime
usually after one or two new trumpets appear.
The flower stalks usually are taller than the trumpets with
deep red, highly fragrant flowers. The flower is structured so that it will be crossed pollinated
naturally by insects. The
flower is in an inverted position and its ovary adjoins the stalk
at the top. Attached
to the ovary, is a style shaped like a five-pointed umbrella.
Each point is a tiny stigma.
Around the ovary are the stamens whose ripe pollen falls into
the umbrella, but not on the stigmas.
After pollination occurs, you may collect the seed after the ovary
turns brown and before it splits, releasing the seeds.
These seed should be stored in a cool dry place, until spring,
when they should be sewn on damp peat and kept moist until they germinate.
Germination usually occurs in about 2 to 3 weeks.
Don’t transplant your seedlings until after their first trumpet-shaped
leaves appear.
When flowering,
the plant produces a side stalk with blooms opening one after another
and ranging from light purple , pink to white.
The flowers self pollinate and produce large amounts of seed
which germinate readily. Plants
with red pigment on the leaves will have purple or pink blooms and
plants without red tent will have white blooms. Seed from either plant can produce blooms of each color without
being cross pollinated. The
healthiest and most colorful plants are achieved by exposing them
to strong sunlight, inside or outside.
This
plant is an active fly-paper trap.
With the digestive glands mainly in the center of the leaf,
the plant will move small insects there.
It will kink or completely roll around larger insects. A healthy
plant is capable of catching prey as large as a fly but normally catches
smaller insects, the larger ones are able to crawl off the leaf.

Cultivation:
For compost you may use peat, live or dead sphagnum or any combination,
thereof. Do not add fertilizer
to the soil, or water it with any liquid fertilizers, for the plant
will catch anything it needs for nutrients.
You may cause serious injury to your plant with a fertilizer.
Also do not use chlorinated water, because the chemicals will
build up in the soil, causing damage or death to your plant.
If you only have chlorinated water, allow it to sit out for 48
hours before using. The
soil must be kept constantly damp at all times during the growing period,
and not allowed to dry out completely when dormant.

Prey:
The Red-Topped Trumpet attracts all sorts of winged insects, such as
flies, wasps and bees and other related insects.

Pests and
Diseases:
When grown indoors, your plant may be attacked by aphids, mealy
bugs or scale. Any insect problem can be eliminated by treatment with
Orthene,
a product of Ortho, which can be purchased through your local garden
center. Fungus may also
become a problem, later in the growing season.
It can be eliminated by treating the plant with Daconil
2787, which is also an
Ortho product and can be purchased at your local garden center. |
