We believe in green roofs and carry a variety of sedums that are particularly well-suited to grow on roof-tops, as well as our grass seed called Enviro-Turf.

Major benefits of green roofs include:

  • storm water retention
  • provides insulation
  • provides cooling
  • cleans the air
  • saves energy
  • sound absorption
  • food production
  • provides a wildlife habitat
  • looks nice
  • can be a place for urbanites to grow food

Bluestem Nursery predicts that by the turn of the next century, most roofs of the world will have plants growing on them. Switzerland requires that all new buildings have a green roof.

More Information

We are not experts on the subject of green roofs (we merely grow the plants). However in the past few years the amount and quality of information available on the Internet has grown considerably, so we provide here a number of links where you can find information. Please research these sites and/or contact them for further info regarding a green roof:

Jim recommends these 2 books: Planting Green Roofs and Living Walls and Green Roof Plants.

A number of grasses have a shallow root system which makes them suitable for a green roof - Bouteloua gracilis and Carex flacca.

Our Enviro-Turf also works well, as is shown in the picture above.
