No, they're not all rampant! We offer some really good groundcovers for dry shade, many with variegated foliage and pretty flowers from winter throught spring and into summer.
Unfortunately most people's experience of Vinca is limited to the invasive Vinca major so often planted in public open spaces in the middle decades of the 20th Century, and the overspill into private gardens from these plantings. The reality is that most Vincas are much more suitable for gardens and even containers than Vinca major.
We grow several forms of the diminuitive Vinca minor (the botanical Latin names do help!) wich will make carpets of evergreen, often variegated, foliage to 15cm and a profusion of flowers mostly in late winter and spring. Surface rooting it is easy to chop through and fork out any excess. Vinca minor is an excellent groundcover for shady areas, even quite dry.
The other Vincas we grow are formed of the mid-sized Vinca difformis and the closely related species Vinca sardoa, which has been moved in and out of Vinca difformis more than once! These are more clump forming plants, with bigger, winter, flowers that will spread by rooting in from runners. The spreading of these types can be controlled by cutting back all the runners in winter, this prevents any rooting in. Vinca difformis and it's forms are favourites here as they produce a lot of their flower in winter but will be found with some flower nearly all year round.
