What looks like wild carrot but is poisonous?

Answered by Jason Smith

One plant that closely resembles wild carrot but is highly toxic is poison-hemlock. Poison-hemlock leaves and roots may initially appear similar to those of wild carrot, but there are some key distinguishing features to look out for.

Firstly, let’s discuss the leaves. Both poison-hemlock and wild carrot have leaves that are deeply divided and feathery in appearance. However, when you examine poison-hemlock leaves closely, you may notice that they have a more fern-like shape with a lacy appearance. On the other hand, wild carrot leaves tend to be broader and have a more triangular shape. So, while they share some similarities, the leaf shape can help differentiate between the two plants.

Moving on to the stems, this is where we can find a distinct characteristic that sets poison-hemlock apart from wild carrot. Poison-hemlock stems, regardless of their age, always display some degree of reddish or purplish spotting. This spotting can be quite subtle in young plants but becomes more apparent as the plant matures. In contrast, wild carrot stems typically lack any purple or red markings and appear green throughout.

Another important aspect to consider is the overall growth habit of the plant. Poison-hemlock can grow quite tall, reaching heights of 5 to 8 feet (1.5 to 2.4 meters), whereas wild carrot tends to be shorter, usually around 2 to 4 feet (0.6 to 1.2 meters) in height. This disparity in height can be helpful in distinguishing between the two if you are able to compare them side by side.

It is worth noting that poison-hemlock is highly toxic if ingested. All parts of the plant, including the leaves, stems, roots, and even the seeds, contain poisonous alkaloids. These alkaloids can cause severe poisoning if consumed, affecting the central nervous system and respiratory system. Therefore, it is crucial to exercise caution when dealing with any plant that resembles wild carrot but displays the characteristic red or purple spotting on its stems.

To summarize, while poison-hemlock may initially resemble wild carrot, there are distinct features that can help differentiate between the two. Poison-hemlock leaves have a more fern-like shape, and its stems always exhibit red or purple spotting, even in young plants. Additionally, poison-hemlock tends to grow much taller than wild carrot. Remember, when in doubt, it is always best to err on the side of caution and avoid consuming any plant unless you are absolutely certain of its identity.
