Planted natural stone walls made of sand-lime brick, greywacke or granite go well with natural gardens. But the wall does not have to stay bare. For planting there is a considerable selection of small perennials that have specialized in this barren habitat and mostly get along with very little water and soil.
The right plants
Among the most popular wall plants include the stonecrop (Sedum), the numerous house root species (Sempervivum), the weed (Alyssum) and the soapwort (Saponaria). These species also tolerate the most dryness. Where it is a bit wetter, also flourish flower (Iberis), Campanula portenschlagiana, Hornwort (Cerastium) and Cymbalaria (Cymbalaria). Even small fern species, such as the pretty striped fern (Asplenium trichomanes) and the stag beetle (Phyllitis scolopendrium), grow in moist, not too sunny wall joints.
The wider joints of a natural stone wall can also be planted with nasturtium, provided the soil is moist enough in it
Wall plants for sun and shade
On a sunny spot in the woods you'll find grasses, bluebells, blue cushions (Aubrieta), St. John's wort, carpet phlox, saxifrage, fat hen, pasqueflower, starfish (Erophila), honorary prize, heather carnation (Dianthus deltoides) and gypsophila. In shady areas, you can plant Larkspur (Corydalis), Toadflax (Linaria), Spotted Fungus, Waldsteinie, Zimbelkraut, Goose Cress or Moss Quarry. Even herbs are suitable for the stone wall planting, because the stones of a drywall warm up in the sunshine. At night, they release this heat gradually - a "natural heating" for Mediterranean herbs such as rosemary, lavender or thyme.
Sedum feels in a sunny location probably in the wall joints, as here in the natural stone wall by Userin Woidgarten
Leave joints open
Already during the stratification of the stones for the drywall, the joints are filled with nutrient-poor earth (no humus) and the plants are used. For retaining walls, pay attention to the ground connection to the rear, so that the plants can hold tight. If you want to plant your natural stone wall later, you should already leave enough wide joints when laying the stones. A gap about two fingers wide enough, many plants even manage with less.
Plant natural stone walls
Natural stone walls can be planted from March to September. First, fill the joints with a substrate that is as permeable as possible, because the roots of all rock garden plants immediately rot in waterlogged conditions. Ideal is a mixture of approximately equal parts potting soil and coarse gravel. It is best to fill the substrate with a narrow spoon in the joints.
Before inserting the plants, fill some of the substrate into the gap (left). The root ball must be cut to the right size (right)
After all joints have been filled, dedicate yourself to the actual planting. Take the perennials out of the pot and split the root ball into several smaller pieces that fit comfortably in the wall joints with a sharp knife. Do not squeeze the roots together, but in case of doubt cut off the bale. Some rock garden species such as the sandflower have only a single, barely branched taproot. They are not easy to divide, so in this case you simply have to reduce the root ball from outside to inside with a knife until it reaches the required size.
Insert the plants in a horizontal position with the root ball as deep as possible into the joints, so that they can anchor well. Embed the root ball on the already filled substrate layer and then fill in some more substrate above the bale. In longer joints is with a few centimeters distance quite some space for two to three plants. When all perennials are in place, they are well watered with a shower or watering can. You must be very careful so that you do not rinse the substrate out of the joints again. In a few weeks, the small plants will grow and nothing will stand in the way of a colorful flower summer.

The sun-loving carnation belongs to the plumbago family and forms a taproot
Alyssum saxatile, to German Alps or Rock Stone Luggage, forms dense cushions and flowers in bright yellow in April and May
The striped fern has a distinctive drawing and is only about 10 cm high. This makes it particularly suitable for the planting of cracks in the wall
The blue pillow is easy to care for and very resistant to drought.On a sunny to partially shaded spot, it forms sweeping upholstery, from March to May with strong flowering flora
The midday flower (Dorotheanthus) is one of the succulents. It blooms only during the day with sunshine in the summer until September
The Paddy Bellflower is an evergreen ground cover that is very hardy. It is also suitable as a subplantation, for example for roses
Sempervivum, the houseleek, comes, as the Latin name says, also in very barren habitat cope. She saves water in her thick leaves
The soapwort belongs to the carnation family. It has strong roots and smells especially in the evening and at night, attracting moths to the garden
The saxifrag (Saxifraga) got its name because it looks through its growth place in crevices, as if it would split the stone. There are now almost 500 different Saxifraga species
