Cranberries are self-fertile, but two plants are a quicker route to cranberry sauce than one. As they last in the fridge for ages, you can harvest over a long period, so it's possible to make your own cranberry sauce for Christmas. Firstly, it is incredibly hardy and can withstand a range of conditions, from hot and dry to cool and damp. If your soil is acidic and naturally damp, try American cranberries, Vaccinium macrocarpon underneath rhododendrons and other ericaceous plants. Thyme is an excellent ground cover for a number of reasons. Or perhaps prostrate rosemary ( Rosmarinus officinalis 'Prostratus') that will cascade down a wall or around paving slabs. Thymus herba-barona, commonly called caraway thyme, is a creeping, woody based perennial which is used as an ornamental ground cover and/or as a culinary. Try the very hardy, 20cm tall broad-leaved thyme, Thymus pulegioides, for general purpose cooking. Unlike its cousin, the thyme, the creeping thyme is not edible, but it does give off a very pleasant fragrance that you are going to like. It is an excellent plant that serves as ground cover to provide protection from the sunny regions in your garden. A slightly unusual one to look out for is caraway thyme, Thymus herba-barona, which is 5cm tall. The creeping thyme is a perennial species of the Thymus. Low-growing herbs are an obvious choice for sunny, well-drained spots: true, there is not a great deal to eat, but they please the bees and bring cheer to many a dish. The prickles are soft, so you can harvest even in bare feet. This is a very low-growing raspberry, which fruits intermittently from late summer into autumn.

The Nepalese raspberry ( Rubus nepalensis) is another suited to the shade cast by trees or buildings, and works well around the base of deciduous trees. I've seen a lovely display under shrub roses and they tolerate a little foot traffic. Caraway Thyme is the only culinary Ground Cover Thyme in the bunch. When transplanting, set the plants 8 to 12 inches apart to allow room for the bushy thyme to expand. This herb grows well from seed which should be started indoors in the early spring before transplanting outside once the risk of frost passes. It cascades nicely down hillsides that aren’t too steep. Creeping thyme can also be divided in the spring or early fall. It can be walked on and is extremely rugged. Its cherry-red fruits are disappointing if you expect a sweet berry flavour, but added to salads they have a satisfying watery crunch, like a mild, sweet radish. Caraway Thyme is the fastest growing and has a pillowy mounding habit instead of a looks like a lawn habit.

The false or mock strawberry, Duchesnea indica, thrives in shade and is evergreen or semi-evergreen, depending on what winter brings. They make the most of space and require little maintenance other than a chop when they meet your boundary. Edible ground cover plants – those that creep and sprawl below tall plants – are invaluable.
