The structure must also comply with current standards (FLL, DIN). Roof structures are subject to many regulations; these must be observed and adhered to! The potting soil mentioned in the video was only lightly sprinkled on top for fertilization. The substrate must not contain more than FLL-compliant organic matter! To the video: How can green roofs be designed to be biodiverse? So-called "biodiversity roofs" can be created using roof substrates with approximately 50% water retention capacity by volume, an "FLL-compliant" organic component, and a substrate depth of at least 12 cm. These substrates allow for the development of low-nutrient, diverse perennial planting areas. Since many insects benefit primarily from native wildflowers, a species-rich green roof can potentially support greater biodiversity (plants and animals). We explain where you can find information and which regulations provide valuable guidance. We'll also take you to a biodiversity green roof currently under construction and show you exactly how to plant and sow wildflowers. Of course, we'll also share the initial results after just a few months of development. Reinhard Witt coined the term "biodiversity roof." Green roofs offer significant potential for biodiversity—but only if they are properly planned, constructed, planted, and maintained. Biodiversity on the roof: With native wildflowers, without invasive species! ``` Substrate: "Höfter Roof Garden" (https://hoefter.de/search?search=dach...) The following wildflowers were used on the roof shown: • 2x Spring Gentian (Gentiana acaulis) • 2x Cross Gentian (Gentiana cruciata) • 2x Stem Carlina acaulis ssp. simplex • 2x Carlina acaulis (varietal?) • 2x Rattle Flower (Catananche caerulea) • 2x Globe Thistle (Echinops ritro) • 2x Musk Mallow (Malva moschata) • 2x Prostrate Speedwell (Veronica prostrata) • 2x Tufted Speedwell (Veronica teucrium) • 2x Dalmatian Bellflower (Campanula portenschlagiana) • 3x Round-leaved Bellflower (Campanula rotundifolia) • 3x Dwarf Bellflower (Campanula cochleariifolia) • 1x Bloody Cranesbill (Geranium sanguineum) • 2x Germander (Teucrium chamaedrys) • 6x Pasque Flower (2 Pulsatilla vulgaris, 4 varieties) • 2x Hyssop (Hyssopus officinalis) • 2x Creeping Yarrow (Achillea tomentosa) • 2x Crown Campion (Lychnis coronaria) • 2x Golden Aster (Aster linosyris) • 2x Maiden Pink 'Albus' (Dianthus deltoides 'Albus') • 2x Common Rue (Ruta graveolens) • 2x Large-flowered Selfheal (Prunella grandiflora) • 2x Purple Toadflax (Linaria purpurea) • 2x Mountain Avens (Dryas octopetala) • 2x Rock Pink (Petrorhagia saxifraga) • 2x Wulfen's Alyssum (Alyssum wulfenianum) • 3x Sticky Catchfly (Lychnis viscaria) • 2x Rock Alyssum (Aurinia saxatilis) • 2x Common Goldenrod (Solidago virgaurea) • 2x Whitlow Grass (Draba aizoides) • 2x Kidney Vetch (Anthyllis vulneraria) • 2x Creeping Soapwort (Saponaria ocymoides) In addition, the "Roof Greening" seed mix from Rieger-Hofmann was sown. Available, for example, here: https://naturgartenshop.com/products/... In autumn, numerous bulbs were planted (approx. 5-10 per m²). These included several Allium species (leeks), such as Allium sphaerocephalon, as well as wild tulips, such as Tulipa sylvestris, Tulipa turkestanica, and several others.
