If you're an avid gardener like I am, you may want to listen up. There is a poisonous plant in Texas called Hemlock that is easily mistaken for a harmless wildflower or weed - and its touch can be deadly. Here's everything you need to know about it:

Hemlock - also known as poison hemlock - looks harmless enough, but in fact, quite the opposite is true.

This highly toxic plant is not native to Texas; it is indigenous to Europe and Northern Africa. The invasive species was introduced to the Lone Star State due to its aesthetically pleasing white flowers.

Partial to full sun and fertile soil, Hemlock primarily grows in northern and western Texas.

It is most highly concentrated near water sources in the Edwards Plateau region. Hemlock has also been found in Lancaster, which is a suburb of Dallas.

This is what the plant looks like in its seed stage. When Hemlock flowers, the blooms have five petals each and are grouped in umbrella-shaped clusters.

Flowers typically appear in the late spring and early summer, and the plant can grow up to nine feet tall. It also has a distinctive, unpleasant odor, and the hollow stems feature purple spots. Hemlock also produces a green, ridged fruit that turns a gray-brown color upon maturation.

What makes Hemlock so insidious is its reminiscence to common garden weeds.

All parts of the plant are toxic - especially when ingested, but simply touching it is enough to trigger a potentially fatal reaction.

Hemlock is so toxic, in fact, that it was used for political executions in ancient Greece.

The famous philosopher Socrates was sentenced to death via ingestion of Hemlock for his crime of corrupting the young people of Athens.

Symptoms of Hemlock toxicity can include everything from facial swelling to dizziness to shortness of breath. Poisoning can also occur through inhaling the plant's fumes.

As far as ingesting Hemlock, just 6-8 leaves can kill a human in about two hours.

If you see a plant that looks like Hemlock in your yard, first put on protective clothing such as gloves, long sleeves, pants, thick socks, and high-top shoes.

Then, dig up all parts of the plant to fully remove it, and dispose of them with the rest of your yard waste. Do not burn or mow the plants, as exposing your skin, lungs, and eyes to the toxic particles can prove deadly.
