Large slopes or gardens with severe gradients can be a bit of a challenge.Exposure, poor soil quality, accessibility and maintenance are usually issues.These are actually the conditions that so many plants thrive on, like herbs, grasses and meadow perennials. In good nurseries there is a wide variety to choose from. Ideally, the smaller the pot size the better the plants adapt to the situation and produce a good root system deep into the ground. Many will self seed and fill empty spaces. Eventually the slope will be covered, and maintenance will be little to none.
