Houstonia pusilla (tiny bluet)[1] is a plant in the family Rubiaceae native to the United States and common in the southeastern and central parts of the country, from Texas to Florida north to [[Long Island ]] and South Dakota, plus an isolated population in Pima County, Arizona.[2]
Houstonia pusilla is a short plant 6 inches (150 mm) or less in height with a tiny blue toned, yellow centered four lobed flower with a 0.25–0.33 inches (6.4–8.4 mm) diameter. The plant has a center rosette form and green herbaceous foliage with leaves up to 0.5 inches (13 mm) long. The leaves are opposite and each flower grows from a single branch growing from the leaf axil. This plant requires full sun and blooms in spring and early summer. It is a groundcover multiplying by self sowing and grows in mildly acidic soil where the grass is thin and moisture is adequate to support the plant.[3][4] Its habitats include dry open places, rocky ledges, granite glades, and outcrops.[5]

Houstonia pusilla est commune dans le Sud-Est et le centre des États-Unis. Elle se rencontre du Texas à la Floride et, vers le nord, jusqu'au Delaware et au Dakota du Sud. Il y a également une population isolée à Pima Comté en Arizona.
Houstonia pusilla est une plante basse de 15 cm de hauteur voire moins. Sa fleur à quatre lobes et au centre jaune mesure de 6,4 à 8,4 mm de diamètre. La plante a une forme de rosette centrale et un feuillage herbacé vert avec des feuilles jusqu'à 13 mm de long. Les feuilles sont opposées et chaque fleur pousse à partir d'une seule branche poussant à l'aisselle des feuilles.
Cette plante a besoin de plein soleil et fleurit au printemps et au début de l'été.
C'est un couvre-sol qui se multiplie par auto-ensemencement et pousse dans un sol légèrement acide où l'herbe est fine et l'humidité est suffisante pour soutenir la plante.
