Houstonia rosea, commonly known as the rose bluet, is a species of flowering plant in the family Rubiaceae. It is native to the central and southeastern United States, where it occurs in a variety of disturbed and open habitats.[2][3]
Description
Houstonia rosea is a small herbaceous plant or subshrub. It produces delicate flowers that are typically pink to rose-colored, a feature reflected in both its scientific and common names.[2]
Flowering occurs primarily from March to April, occasionally beginning as early as February in warmer portions of its range.[3]
Distribution and habitat
The species is endemic to the central and southeastern United States, including Alabama, Arkansas, Louisiana, Mississippi, Missouri, Oklahoma, and Texas.[2][4]
It is typically found in bottomlands, lawns, and other disturbed or open habitats.[3]
Taxonomy
The species was originally described as Hedyotis rosea by Constantine Samuel Rafinesque in 1817 and later transferred to the genus Houstonia by Edward E. Terrell in 1986.[5]
Synonyms
Synonyms of Houstonia rosea include:[2]
- Hedyotis rosea Raf.
- Hedyotis minima f. albiflora Lathrop
- Hedyotis taylorae Fosberg ex Shinners
- Houstonia minor var. pusilla (A.Gray) Small
- Houstonia patens var. pusilla A.Gray

Conservation
Houstonia rosea is ranked as globally secure (G5) by NatureServe, indicating that it is widespread and not currently at risk of extinction.[1]
At the state level, conservation status varies; for example, the species is considered apparently secure (S4) in Mississippi but possibly extirpated (SH) in Missouri, while remaining unranked or not assessed in several other states.[1]
The global conservation status has not been recently reviewed.[1]
