Stachys floridana, also known as Florida betony, is a plant that belongs to the mint family. It is originally from the United States, likely only from Florida. However, it has spread and is now found all over the Southeast. It is considered an introduced species and a common weed. You can find it as far west as Texas, and it has even been seen in California. People call it by many names, including Florida hedgenettle and rattlesnake weed. Some even call it wild artichoke, but it is not related to the real artichoke.

What Does Florida Betony Look Like?
This plant is a perennial herb, meaning it lives for more than two years. It has a hairy stem that can grow up to about half a meter (about 20 inches) tall. The plant grows from a network of underground stems called rhizomes. These rhizomes have special parts called tubers.
The tubers are light-colored and unique. They are several centimeters long and about one centimeter wide. They have segments that look like the rattle on a rattlesnake's tail. This is why one of its common names is "rattlesnake weed." Some people say the tuber also looks like a "fat grub." In sandy soils, these tubers can grow very long, sometimes up to one meter (about 3 feet)!
The leaves grow in pairs opposite each other on the stem. Each leaf blade can be up to 5.5 centimeters (about 2 inches) long. They grow on stalks called petioles, which can be up to 3.5 centimeters (about 1.4 inches) long.
The flowers grow in groups of 3 to 6. They appear where the leaves meet the stem. The flowers have a hairy cup-like structure called a calyx, which has pointed tips. The flower itself is shaped like a tube and has two lips. It can be up to 1.3 centimeters (about half an inch) long. The color ranges from white to pink, often with purple spots or darker lines. After flowering, the plant produces a fruit called a schizocarp. This fruit is a few centimeters long and splits in half. The tiny seeds inside are about a millimeter long.
How Does Florida Betony Grow and Reproduce?
This plant produces many seeds. However, it often spreads in another way, using its rhizomes and tubers. This is called vegetative reproduction. Even small pieces of a rhizome can grow into a new plant. The tubers can also be moved to new places, which is probably the most common way the plant spreads.
Florida betony likes to grow in places where the ground has been disturbed. You can often find it along roadsides, especially in wet soil. It also grows well in lawns and in garden beds where people plant ornamental plants.
Why is Florida Betony a Weed?
Until the 1940s and 1950s, Florida betony was mostly found only in Florida. But then it started to spread across the southeastern United States. Its rhizome system can easily grow into the loose soil of gardens and cultivated areas. Because of this, it became a common weed in homes and businesses.
You can find it in lawns and other grassy areas. It is especially common in certain types of grass like centipedegrass and St. Augustine grass. It is also a problem weed for ornamental plants. It can be harder to control in these areas than in lawns. This is because there are fewer chemicals (called herbicides) approved for use on ornamental plants compared to lawn grasses.
Florida betony is one of the worst weeds for a cultivated ornamental plant called leatherleaf fern (Rumohra adiantiformis). To get rid of it in ornamental gardens, people often have to pull it out by hand. They must be careful to remove all the tubers to stop it from growing back.
Can You Eat Florida Betony?
Yes, the tuber of the Florida betony plant is edible! It is similar to its relative, the Chinese artichoke. The tuber is described as "crisp" and "succulent." It has a pleasant crunchy texture and a mild, slightly sweet taste.
