Sometimes there are spots on the leaf plates or a border of cream color. Single large periwinkle flowers growing from the leaf axils are colored pink, white or purple. The funnel-shaped Corolla has a cylindrical long tube.
Mass flowering of this periwinkle plant is observed in the spring. At this time, the periwinkle flower looks especially attractive due to the fact that its flower stalks rise up. After most of the flowers wither, the plant will continue to bloom. Individual flowers are present on the Bush throughout the growing season. The fruit is a pair of cylindrical leaflets. In the wild, about 12 species of this periwinkle plant grow.

Planting cuttings for rooting is performed in open soil and done in the spring or in the last days of August or the first-September. The distance between the cuttings should be from 0.2 to 0.3 m.
For the reproduction of evergreen species, dead shoots are used, and the technique of horizontal layering is used. To do this, sprinkle the stem with a thin layer of soil, and soon it will have roots.
