A perennial of the Primulaceae family, this primrose is native to Yunnan and Sichuan, in southwestern China, where it grows in wet meadows and stream banks at altitude, between approximately 2,500 and 3,500 meters. It belongs to the Proliferae section, the group of candelabra primroses.
It forms rosettes of elongated, oblong-spatulate leaves, with finely toothed margins, bright green, slightly rough. The floral stems, upright and robust, reach 20 to 40 cm and bear the flowers in superimposed whorls according to the typical candelabra habit of the section. The color is one of the most distinctive traits of the genus in this group: the flowers are bright orange to true orange-red, with an orange eye, borne by pedicels and calyces of a very pronounced dark red to purple-brown, visible on the tight buds that crown each whorl before anthesis. This contrast between the warm tones of the open flowers and the dark mass of the still-closed buds is immediately striking.
In its natural habitat, its flowering extends from May to July depending on the altitude. In cultivation, it generally blooms in May-June.
It requires a humus-rich soil, constantly fresh to moist, in a sunny or lightly semi-shaded position. It is suitable for the edges of water bodies, moist woodland gardens, and natural compositions in a sufficiently cool and rainy climate.
