Perennial of the Polemoniaceae family, selected from Phlox amoena, a species native to the southeastern United States, where it grows in open pine forests, sandy clearings, and sunny edges of the southern Appalachian states.
The 'Rosea' cultivar forms semi-upright, bushy clumps 15 cm in height, wider than tall, with evergreen foliage of small, dark green, slightly hairy, lanceolate leaves densely arranged along the stems. The young stems are often tinged with dark red, enhancing the contrast with the flowers.
These are a bright, warm pink, with five widely spread and slightly notched petals, gathered in generous terminal corymbs that can almost hide the foliage at the peak of flowering. The center of each flower is marked with a small orange to red eye.
In its natural habitat, the species blooms from April to June. In cultivation, 'Rosea' generally blooms in April-May, sometimes with a slight resurgence.
It requires well-drained, moderately fertile soil, in full sun or very light partial shade. Robust and floriferous, this cultivar fits well in rock gardens or sunny borders.
