Green roofs are finally hot, hot in the U.S. and Emory Knoll Farms is working hard to fill 'em with plants.
The only nursery in N. America dedicated exclusively to supplying plants for green roofs, it has 230 projects under its belt - in the U.S. and around the world - and business is booming. That's our Business Section report.
The Home Section might include the findings that green roofs hold up better than traditional roofs in the leak department. Seems counter-intuitive but it's the heat, stupid! All that growing medium and all those plants keep the roofin
g membrane much cooler, not to mention protected from puncture by flying objects and humans. And now there are even green walls, built using these nifty planter components, and they're not only better looking but greener in every way.
Our Sty
le Section story starts with the sign that greeted me on my recent visit to the Maryland nursery. (Wearing my best Frank Zappa T-shirt, I headed straight for the side door.) And here's Ed, Mr. Green Roof himself. His family's farmed this land since - would you believe? - 1709. Not long ago Ed put 60 of his 145 acres into an agricultural preservation trust for indigenous trees and meadow. Then to support his family he transitioned the homestead from traditional monoculture farming to the production of green roof plants using sustainable growing techniques. So on the enviro-scale he's up there with Al Gore.
Now the A Section should but probably wouldn't tell you that with global warming, green roof
plants may become our most popular garden plants. And what ARE the
world's most drought-tolerant hardy plants? Mostly sedums, plus ice
plants and chives. They're watered in just once after installation and
never again. My kind of plant. (Check their website for lots more info.)
Having read all about Chicago's great adventures in greening,
including on its rooftops, I was surprised to learn that D.C. has more
greenroof acreage than any U.S. city, thanks to the sheer size of its
buildings. That's because the decidedly unsexy agency in charge of
federal buildings (the GSA) is a BIG promoter of green roof technology
(go Bureaucrats!). And while lots of research is going on in green
roof
engineering,
on the hort side of the picture - not so much. So Ed here puts on his
lab coat, teams up with some universities, and does the research.
Finally, the Book Section. Sometimes good things happen to good people and in
this case Timber Press jumped at the chance to publish Ed (and wife Lucie's) book, being released this week. Advance orders
are being taken. Now let's all place our orders and demonstrate to the
publishing world the immense reach of a gardenblogger endorsement!

This is amazing. I grew up in northern Maryland and worked for a few years at manor view farms. My friend Marc and I have been working in the landscape and construction fields for a long time. Marc lives in Baltimore and I live in Asheville NC. Both of us have been very excited about these ideas for some time. Marc has some very interested clients and would love to bounce some ideas and make these things happen in both areas. I will be in Baltimore soon and I would love to visit the farm and talk more. Keep up the good work!

You may offend some people, especially outside the U.S., by the trying to be clever and funny with the (stupid) remark. I wanted to copy this to a company but will have to alter it as it sounds juvenile.
