The smaller version of hogweed is known as common hogweed, scientifically named Heracleum sphondylium. As a gardening and landscaping expert, I have encountered both common hogweed and its larger counterpart, giant hogweed, in various situations. It is important to be able to distinguish between the two, as giant hogweed can cause serious health issues if handled improperly.
Common hogweed closely resembles giant hogweed in appearance, but it is significantly smaller in size. While giant hogweed can grow to heights of 10 to 15 feet, common hogweed typically reaches only around 3 to 6 feet in height. This size difference can be quite noticeable when comparing the two side by side.
One of the key visual differences between common hogweed and giant hogweed lies in their stems. The stems of common hogweed are not blotchy like those of giant hogweed. Instead, they have a smooth color gradient, transitioning smoothly from green to purple. Additionally, the stems of common hogweed are ridged, giving them a slightly textured appearance. They are also hollow and covered in fine hairs, providing a fuzzy texture when touched.
When it comes to leaves, both common hogweed and giant hogweed have similar characteristics. The leaves of common hogweed are large, typically measuring between 6 to 12 inches in diameter. They are deeply lobed and have toothed edges, giving them a distinct appearance. The leaves are arranged in an alternate pattern along the stems, forming a lush foliage.
In terms of flowering, common hogweed produces clusters of small, white flowers that are arranged in umbels, similar to giant hogweed. These flowers attract pollinators such as bees and butterflies. The flowering period for common hogweed usually occurs from late spring to early summer, adding a touch of beauty to gardens and natural areas.
One important aspect to note is that while common hogweed is smaller in size and less harmful than giant hogweed, it can still cause skin irritations and reactions in some individuals. It is always advisable to wear protective clothing, including long sleeves and gloves, when handling any type of hogweed to avoid potential contact with its sap.
The smaller version of hogweed is known as common hogweed (Heracleum sphondylium). It can be identified by its smaller size compared to giant hogweed, with smooth green to purple stems that are ridged, hollow, and covered in fine hairs. The leaves are large, deeply lobed, and toothed, while the flowers are small and white, arranged in umbels. While less harmful than giant hogweed, caution should still be exercised when handling common hogweed to avoid potential skin irritations.
