The Poison Hemlock Herb
Welcome!
This webpage is devoted to the knowledge
of Conium maculatum, commonly known as
poison hemlock. Throughout this site, you
will discover more about this species and
hopefully gain an appreciation for the beauty
of this plant.
Identifying Conium maculatum
The poison hemlock plant is usually 120-180 cm high. During the first year of
growth, C. maculatum reaches 45 cm in height, and forms dense stands around the
parent plants. In the second year, new plants grow from rosettes, with larger leaves
that are dark, green, bisected, and triangular. The root is long, forked, tuberous,
and has a pale-yellow color that resembles that of a carrot. The stem is hollow and
is mottled with irregular purple spots, is erect, bright-green and ridged. The leaves
are fern-like and it has flowers that are white and the plant produces a large number
of green fruits, 2 to 3 mm long and about 2 mm wide. Many of these characteristics
can help to classify this organism.
Why should you care about Conium maculatum?
C. maculatum actually brings forth quite a paradox with how humans have
interacted with this species. On one end of the spectrum, the by products of C.
maculatum's nutritional lifestyle provides us with oxygen. Without oxygen, we
would die. However, C. maculatum also produces a very toxic chemical that can kill
humans. In fact, these toxins were once used to kill condemned prisoners! Also, it
might be startling to know that C. maculatum has adapted to live in close perimeters
with us. This species covers quite a large range of habitat throughout the United
States.
What is my purpose in making this page?
As part of the organismal biology course at the University of Wisconsin - La
Crosse, students are required to create and publish a webpage on a particular
organism just as so. Each year there is a new theme and this year's was poisonous
and venomous organisms! You can find plenty of other cool organisms from the
giant pacific octopus to cat fleas, all done by students in years past at
