FutureStarrSabatia Angularis or
Like other species in this genus, Common Rose Pink is a showy and attractive plant. It resembles an oversized version of Centaurium pulchellum (Branching Centaury) from Europe, which is also in the Gentian family. Another species, Sabatia campestris (Prairie Rose Pink), also occurs in Illinois; it is usually found in drier habitats. Prairie Rose Pink differs from Common Rose Pink by its tendency to branch alternately, rather than oppositely. It also has 5 vertical ribs along the tubular portion of its calyx, while the calyx of Common Rose Pink lacks such ribs. Other common names that have been applied to Sabatia angularis include Rose Gentian, Marsh Pink, and Bitterbloom.
Similar species: Sabatia angularis is quite similar to S. campestris (though it is now believed extinct in our area), but that species is an annual lacking basal rosette leaves, the branches of the inflorescence are mostly alternate, the fused sepal tube is longer and has very strong wings or ridges running up its outer sides, and although it has a noticeably angled stem, there are no wings. The other similar species, S. campanulata, has a very restricted distribution (only in one county in the Chicago Region) and differs because it is a perennial, the stems are round in cross-section, the leaves do not clasp the stem at their bases, and the fused sepal tube is shorter (about as tall as broad), not angled, and thin and papery in texture, rather than green.Latin Name/Common Name- Sabatia angularis is one of the approximately 20 species in Gentianaceae family of flowering plants. Sabatia angularis, is named for Liberato Sabbati, an 18th Century Italian botanist. The term angularis, Latin for angular, refers to the angled stem. Among the many common names used in various parts of the country are Sabatia, Rose gentian, Rosepink, Rose Marsh, Bitter Clover, Eyebright, Red Centaury, American Centaury, Wild Succory and Bitterbloom. Sabatia is in the Gentianaceae family.
Habitat- On Ozarkedge, I find sabatia seem to prefer low, moist areas at the edges of rocky, open woods and in fields where they can find the sun. Sabatias grow in loose groups rather than tight clusters. If you find one, you will likely see more nearby. In the literature, Sabatia angularis is described variably as an annual, perennial or biennial. However, in 1971, J.D. Perry confirmed that it is a biennial plant. The seeds germinate in spring and develop a basal rosette that persists through winter and sends up blooms the next summer.Gray, 1877 N Triodanis biflora (Ruiz & Pavon) N Greene, 1894 Clusiaceae Hypericum mutilum L., 1753 N Commelinaceae Tradescantia ohiensis Rafinesque, 1814 N Fabaceae Aeschynomene viscidula Michaux, 1803 N Chamaecrista fasciculata (Michaux) N Greene, 1897 Desmodium incanum de Candolle, 1825 Medicago lupulina L., 1753 Melilotus albus Medicus, 1787 Trifolium repens L., 1753 Gentianaceae Sabatia angularis (L.)
