Primula
The genus Primula has about 500 species in the world. Two-thirds of them are distributed in Himalayas and Hengduan mountains. These species and many others are valued for their ornamental flowers. They have been extensively cultivated and hybridized - in the case of the primrose, for many hundreds of years.
Primula sikkimensis
These plants bloom mostly during the spring, with flowers often appearing in spherical umbels on stout stems arising from basal rosettes of leaves. Their flowers can be purple, yellow, red, pink, blue, or white, even black.
