The small leaved evergreen Vincas (Vinca minor) are available in several shades of blue, white - V. minor Alba - as above and also a deep purple. There are also a few with variegated leaves - aureovariegata with golden blotched leaves probably the best. There are also one or two double-flowered cultivars available. (There are also the larger leaved Vincas - Vinca major. Not my favourites!)
The periwinkles are great for ground-cover, flowering best on a sunny bank, though also happy in part shade beneath trees and shrubs. They do not like the soil to be too dry, so if planted on banks, then ensure a supply of water in hot summers. They will spread well after establishment, and can be restrained - to a certain extent - by cutting back in early spring.
Propagation of Vinca minor Alba - and the other Vinca varieties is easy. Either divide the mature plants, or dig up rooted 'layers' in Autumn or Spring and plant into new position.
