Thistle plants are known for their medicinal properties.
They’re used to treat various diseases such as arthritis, asthma, diabetes, gout, kidney stones, liver problems, rheumatism, and ulcers. Thistle plants are also used to prevent hair loss, and in some parts of the world, as an aphrodisiac.
Let’s take a look at some fine specimens of the species, shall we:
1. Common Thistle
The common thistle is one of the most well-known and widespread thistle plants. Growing up to 5 feet tall in fields, meadows, and along roadsides, their spiky stems and leaves have prodded many a hiker, yet despite their prickly disposition, they have been intentionally cultivated for thousands of years.
Common thistles are perennial herbs that produce large, bulbous, purple flowers, which are quite striking, but not striking enough to shake the “weed status” given to this plant by green thumbs around the globe.
Not many people know this, but the humble artichoke is actually a type of thistle plant. Artichoke has become a popular vegetable because it grows quickly and can be harvested before it reaches maturity. It is very easy to grow from seed or cuttings.
The piece of the artichoke thistle we eat is actually just the bud of this amazing plant.
3. Carline Thistle
Carline thistles are native to Europe and Asia, where they grow wild on dry hillsides and waste areas. The carline thistle has long, slender, hairy stalks with small, round, grayish-green leaves. It produces white or pink flowers at the end of its stem.

Dandelions are one of nature’s most versatile plants. They grow easily in almost every environment, thrive in poor soil, and provide food for many animals.

As you can see, the thistle family is large and diverse. Each plant has its own unique characteristics and uses, so next time you see one cropping up in your yard, instead of reaching straight for the herbicide, pay your respects to this proud and helpful plant.
