Stachys floridana is a species of betony in the mint family, Lamiaceae. It is native to the United States, where its true native range is probably limited to Florida, but today it is known throughout the Southeast as an introduced species and common weed. It occurs as far west as Texas, and it has been recorded in California. Its common names include Florida betony, Florida hedgenettle, and rattlesnake weed.

Paronychia rugelii, common names Rugel's nailwort and sand-squares, is a plant native to the US states of Georgia and Florida. It can be found in woodlands and on disturbed sites at elevations below 200 m (667 feet). They are sometimes referred to as sand squares. Paronychia rugelii is an annual herb up to 50 cm (20 inches) tall, nearly the entire above-ground parts with hairs. Leaves are ovate to lanceolate, up to 6 mm (0.24 inches) long.

Rugelia nudicaulis (Rugel's Indian plantain or Rugels ragwort), the sole species of the genus Rugelia, blooms in summer. It is a wildflower endemic to higher elevations in the Great Smoky Mountains. It is a rare species in Tennessee. Genetic diversity in this plant, assessed using allozymes, is so low that the species may not survive changing environmental conditions. Both the scientific name and the common names honor Ferdinand Rugel, a botanist and plant collector who collected plant specimens throughout the southeastern United States during the period 1840–1848.
