Trees and shrubs are getting bigger - and with it, their shadow. Therefore, when designing your garden, take into account the places where partial shade or shady corners will emerge over time - and select the plants accordingly. Large trees are in the garden but not the only shade donors. Terraced gardens are often surrounded on all sides with walls, screens or hedges and therefore have different bright areas depending on the position of the sun, which are often sharply separated from each other. Since the shade can vary in severity, when selecting a suitable cookie for each garden plant, a distinction is made between the serene location, penumbra, light shade and full shade. We explain the differences.
The term "absonnig" is not clearly defined. Often sites are considered to be absonnig, although they are very bright, but get no direct sunlight. A typical example is courtyards whose bright walls reflect the sunlight. From an absonnigen location but also speaks, if it is protected only at lunchtime from direct sun. Abandoned locations are usually so bright that even hungry perennials and shrubs grow well here.
The penumbra is a shadow front that arises during the day, for example through walls, hedges or tall trees with dense crown. Beets in partial shade are sunny during the day for up to four hours, but are otherwise shadowed. The ideal plants for such areas tolerate at times blazing sun and keep out short soil dryness. Morning suns tolerate most of the half-shade plants better than afternoon sun: Early in the day, the risk of burns is lower because the high humidity compensates for part of the heat. Typical plants for the penumbra are star umbels (Astrantia), autumn anemones, digitalis and various cranesbill species (geranium).
The star-throde is a beautiful perennial for partially shaded locations
A light shadow is when the sun's rays and shorter shadow times are constantly changing. This spectacle, often intensified by the wind, can be seen under the light canopy of birches or willows, but also a bamboo hedge or a covered pergola let mild stray light through. In such places grow essentially the same plants that thrive well under half shady conditions.
The small, thin leaves of the birch cast a light shadow. But beware: their roots dry out the soil
Garden areas into which hardly a ray of light penetrates all day are in full shade. Such a low-light location is often found under coniferous trees, evergreen shrubs or on the north side of higher walls and buildings. They are an ideal location for true shade perennials such as Rodgersien, Christ and Lenzrose (Helleborus), Funkien (Hosta) and ferns. Deep Shadow is a case of Liliaceae (Liriope muscari), Bleeding Heart (Dicentra spectabilis) or Foam Blossom. Also evergreen (vinca) and pops (Astilbe) illuminate the full shade.
The hellebore (Helleborus Orientalis hybrid) is usually in the shade during the flowering season in February / March, because the treetops in the spring still have no leaves. During the summer, however, their location is often in full shade
The transitions between the different shadow types are fluid. Some shade plants such as woodruff (Galium odoratum), spurge (Euphorbia amygdaloides var. Robbiae), hellebore (Helleborus foetidus) and lady's mantle are flexible and grow in almost all different intense shadow areas. By the way: Sunny is almost always enough with sufficiently moist soil. Even large-leaved perennials such as the funerals grow in the sun as long as the roots can supply enough water to cool the leaves. But if the soil becomes too dry, its leaves will burn very quickly.
