The genus Vinca has five species in Central and Southern Europe, but only the little periwinkle (Vinca minor) is present in our hardwood forests.
At the level of horticultural production, we find at home especially Vinca minor as well as Vinca Major and Vinca balcanica, but in much smaller numbers.
The plant retains its lanceolate leaves divert dark brilliant, during the whole season.
Thanks to its long stolons, it quickly sets out to conquer large areas. Its natural locations are forest edges and clearings with loose, nutrient-rich soils.
That the periwinkles feel the most, and that all their splendor may be displayed.
I prefer to see periwinkles in sunny to semi-midden locations, associated with dwarf shrubs or perennials of large size.
Vinca is also suitable as a cover for shaded areas, but they give fewer flowers.
This is the ideal time to plant the periwinkles: plants spin very well, even when temperatures are low, and start the spring in a solid way.
Before planting, it is advisable to rid the soil of all perennial weeds.
Varieties from of culture
As the purple wild blue variety is little demanding, but does not bloom a lot and is prone to diseases, it lends itself very little to use in the garden. My father, Herbert Menke, has managed to obtain seeds that can germinate by crossing selected male varieties and the parent variety Jekyll ‘. He created four new varieties. The goal was to have a compact habit, with many branches and flowers and a healthy foliage.
Periwinkle carpets are an important source of food. When combined, the different varieties are particularly attractive.
