Is Eryngium the Same as Thistle?
When it comes to the question of whether Eryngium is the same as thistle, the answer is both yes and no. While they share some similarities, they are not identical plants. Let’s delve into the details to better understand the relationship between Eryngium and thistle.
1. Taxonomy and Classification:
Eryngium and thistle belong to different plant families and have distinct taxonomic classifications. Thistles are part of the Asteraceae family, which includes a wide variety of flowering plants such as sunflowers and daisies. On the other hand, Eryngium belongs to the Apiaceae family, also known as the carrot family, which includes plants like carrots, parsley, and celery.
2. Appearance:
Both Eryngium and thistle have spiky or prickly leaves, which may contribute to the confusion between the two. However, there are some noticeable differences in their appearance. Thistles typically have larger and broader leaves compared to Eryngium, which often has narrower, more elongated leaves. Additionally, thistles are usually taller and more robust in stature, while Eryngium tends to be smaller and more compact.
3. Flowers:
One of the key distinguishing features between Eryngium and thistle lies in their flowers. Thistles typically produce large, showy flowers in shades of purple, pink, or white. These flowers are often surrounded by spiky bracts, giving them a distinctive appearance. In contrast, Eryngium flowers are usually smaller and have a unique blue color. The flowers of Eryngium are often arranged in globular or cone-shaped clusters, adding to their overall charm.
4. Common Names:
The common names given to plants can sometimes be misleading, as they vary from region to region. While thistles are commonly referred to as such, Eryngium goes by several different names, including blue devil, blueweed, sea holly, and viper’s bugloss. These common names may differ based on cultural, historical, or regional factors.
5. Cultivation and Uses:
Thistles are often considered invasive weeds in gardens and landscapes, as they can spread rapidly and be challenging to control. However, some species of thistle, such as the globe thistle (Echinops), are cultivated for their ornamental value. Eryngium, on the other hand, is a popular choice for gardeners and landscapers due to its unique appearance and ability to attract pollinators. It is often used in flower arrangements and adds an interesting texture to floral displays.
While Eryngium and thistle share some similarities in terms of appearance and spiky leaves, they are not the same plant. Thistles belong to the Asteraceae family, while Eryngium belongs to the Apiaceae family. The flowers, common names, and cultivation practices also differ between the two. Understanding these distinctions can help gardeners and plant enthusiasts appreciate the unique qualities of both Eryngium and thistle.
