The dry conditions of a rock wall make it difficult for many plants to thrive. However, there are good candidates for these environments, and they are often plants that have small root systems and are reseeding annuals.

The pink and white color of the fleabane is a hardy option, and it has the ability to reseed in the smallest of cracks. Other plants that can be grow in a wall include the candytuft, ice plant, hens-and-chicks, lavender cotton, pinks, rock cress, snow-in-summer, thrift, wooly thyme and yellow corydalis. Thyme and sedum are also known to thrive in small spaces.

Some tips to make it easy for the plants to grow include planting as you build your wall or at least leaving enough space between the rocks to plant the root. Also, a landscape fabric can prevent your nutrient-rich soil and seeds from being washed or blown away. If you want to plant on an existing wall, use a butter knife to get the seeds into the crevices and make sure there is enough soil and water.
