Family:
Sarraceniaceae
Genus: Sarracenia
Common Name : Yellow Trumpet, French, Sarracene a fleurs janunes.
Origin: Southeastern United States (Virginia to Florida,
favoring coastal plains). |

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 flava
are shaped like tubular trumpets, are erect with a hood covering.
The mature height may reach 4 feet.
These leaves grow from a rhizome which grows at the surface
of the soil. Each rhizome
will produce 3 to 5 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 flava
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
yellow trumpet are bore in the springtime usually before any of the
new trumpets appear. The
flower stalks usually are taller than the trumpets with bright yellow
or yellow-green flowers and petals.
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.

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
Yellow Trumpet attracts all sorts of winged insects, such as flies,
wasps and bees and other related insects.
Larger trumpets have been known to capture small birds.

Pest 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. |
