If you are looking for a colourful groundcover that is slower growing & not going to take over, then consider Trachelospermum – Tricolour.
 
TrachelospermumTricolourCu420With beautifully variegated leaves this creeper can be easily kept in check and can be maintained into decorative mounds throughout a garden bed. With leaves that range from green though to white to pink, this plant is worthy of a spot in most gardens.
 
Left to sprawl over the garden bed surface, this groundcover will provide a dense coverage ensuring to minimize weeds from germinating. Trachelospermum Tricolour lacks a stunning flower like other varietes (Star Jasmine) but rather a small, fragrant pinkish-white flower.  The variegated foliage of this plant is a feature in itself.
