Hartwrightia is a special type of flowering plant found in North America. It belongs to the sunflower family, which is a very large group of plants. There is only one known species in the Hartwrightia group, and it's called Hartwrightia floridana. This plant grows naturally in the US states of Georgia and Florida. Sometimes, people call it the Florida hartwrightia.
This plant looks a bit like some other plants in the Eupatorium group. However, you can tell it apart by a few key features. The Florida hartwrightia has leaves that grow in a circle close to the ground, like a rosette. Its flowers also have a different shape. Plus, its fruit doesn't have the fluffy, parachute-like part that helps other sunflower family seeds fly in the wind. This plant usually grows to be about one meter (about 3 feet) tall. It blooms in the fall, and its flowers can be white, pink, or even blue.
The name Hartwrightia was given to honor Samuel Hart Wright (1825–1905), who was a plant collector.

Understanding the Florida Hartwrightia
What is Hartwrightia?
Hartwrightia is a genus (a group of closely related species) of plants. It is part of a larger group called the Eupatorieae tribe, which is a big part of the sunflower family. Other plants in this tribe include Liatris, Carphephorus, and Garberia.
Scientists study the DNA of plants to understand how they are related. For Hartwrightia, DNA tests show some interesting things. Some tests suggest it is closely related to a plant called Trilisa. Other tests show it is very similar to Carphephorus corymbosus. These mixed results make scientists wonder if Hartwrightia might have come from a mix of two different parent plants a long time ago.
Where the Florida Hartwrightia Lives
Hartwrightia floridana is a perennial herb. This means it's a plant that lives for more than two years and has soft stems, not woody ones like a tree. It grows in the southeastern United States, specifically in Georgia and Florida.
You can often find this plant in open areas, like sunny pine flatlands. However, it doesn't do well if animals graze on it too much, or if it's completely covered by a dense forest. It seems to grow best in places where there are regular fires. These fires help clear out other plants and keep the area open and sunny.
Why This Plant Needs Our Help
The Florida hartwrightia is considered a threatened plant. The biggest danger to its survival is the loss of its natural home. It needs wet soil to grow, so changes in water levels or drainage can really hurt it.
The plant's seeds are sticky and don't have a fluffy "parachute" like some other seeds that are carried by the wind. Because of this, scientists believe its seeds are likely spread by animals that brush against them or eat them.
