The Ford Plant in Dearborn,MI
These men are installing a Green Roof at the Ford Motor Co.( the photo was taken by J. Kyle Keener and ran in the Detroit Free Press.) This is Very Good News. Green roofs have been used all over Northern Europe for decades with Germany taking the lead, but now are just beginning to be favored in the U.S. by the corporate world.  Green roofs improve the famous bottom line .No,we are not talking about how well you will look in your new jeans but something closer to the corporate heart---profit.Suddenly sedums are IN. Not to mention sempervivums.

Semperviums are alpine plants, sedums come from all over. Sedum are also called "stonecrop". They work better on roofs than grass since their succulent leaves store water.They are also quite beautiful.You can see lots of them on this site: www.sempergreen.com .
