Extensive Green Roof “Rockery Type Plants” – Sophisticated Design and Individual Character

Extensive green roofs call for plant communities that can easily deal with sun, wind and drought. The system build-up “Rockery Type Plants” leads to an extensive green roof with sophisticated design and individual character. The substrate has a minimum depth of 80 mm and the vegetation consists of various species which provide a long blooming period and set different accents throughout the vegetation period.

Water and nutrients are mostly supplied through natural processes. Rainfall collects in the Floradrain® storage cells and roots are provided with water through diffusion. Water is also stored in the protection mat. Excess water is drained away by the Floradrain® element.

Sedum species and other perennials are primarily used as a ground cover. The vegetation of “Rockery Type Plants” is obtained by root ball plants. Hand-planting ensures the design agrees with the landscaping drawings.

The system build-up “Rockery Type Plants” can also be combined with seed-sowing. Different seed mixtures, such as “Meadow Scents”, “Country Colours” and “Grassy Pasture” provide green roofs with a very attractive back to nature appearance.
