For some, growing a garden in the backyard is a challenge, but imagine growing one on your roof.

In this week's "Your Green Life" Meteorologist Jeff Edmondson checks up on a green roof that was planted just over a year ago.

What a difference a year can make...this green roof on the Yellow Jacket Student Union Building at the University of Wisconsin–Superior began with several different layers of material before the Sedum was planted.

"It has got a nice base layer; a lot of the other sedum plants are starting to sprout up and starting to propagate," said Tom Fennessey at UWS.

Besides some occasional irrigation, the UWS Green Roof has held up well.

"The roof has been performing excellently; it's the first year of the growing season, within a couple of years it is going to be fully matured, said Tom"

The staff says with full maturity the roof–top garden will be able to eliminate storm water runoff and even cut down on some of the energy used to heat and cool the interior.

"Its such a thick layer with soil and plantings it creates an excellent blanket for heating and cooling, it reduces our heating loads it reduces our cooling loads during the summer," said Tom.

Since the Student Union center opened in January, the staff has been gathering results to see how the energy usage matches up with that of other buildings on campus.

UWS staff says the reddish plants that are visible now will, by next summer, mature into tall green plants with four colors of blossoms.
