Chicago's City Hall is one of the United States' best known green roofs. Installed in in 2001, this green roof is actually quite similar to the Berry Prairie in concept: it was installed as an experiment, an education and outreach tool and to create a diverse mini-ecosystem. They have over 100 species on that roof!

It could be argued that asters are the most successful plants in the world. The family named for them, the Asteraceae, is the largest plant family (with nearly 23,000 species!), and contains many familiar wildflowers. Also called the Sunflower Family, the Compositae, or composites, the members of the family are united in having “flowers” that are really inflorescences composed of many small flowers.

Some of you may know Dorothy, the Berry Center's associate director. She's a native plant guru - slash non-native plant bouncer - who broke the undercover identity of the Sphaeralcea munroana, the horticultural variety of Sphaeralcea coccinea. As you may have read earlier, Sphaeralcea coccinea is our lovely native plant called Cowboy's Delight or Scarlet Globemallow. Dorothy noted there were two species that were both labeled Sphaeralcea coccinea, but they had obvious visual differences.

Not a prairie plant guru? No problem! Now on the Berry Prairie are plant identification tags so you can stroll through and know what you're looking at. There are nearly 60 species of grasses, forbs (wildflowers) and shrubs on the Berry Center's green roof, so the name tags will help you recognize a number of the plants that grow in the Laramie basin.

Green roofs are not a new concept. Centuries ago, Norwegians began using turf roofs to insulate their houses through the long winters, home owners and builders in Iceland and Germany have been improving the green roof technology over the past 250 years, and if you really want to stretch it back, the floating gardens of Babylon were maybe the first uses of green roofs. Heck, even Frodo Baggins and Laura Ingalls Wilder had one… supposedly.

The Berry Prairie includes four of the 11 species of Penstemon that are native to the Laramie Basin. Also known as beardtongues, many penstemons are adored by gardeners for their form and their vivid colors, which range from white through pink, red, purple and blue.

The Berry Prairie, and likewise the native prairie, is dominated by grasses. In fact, there are nine species of grasses on the roof, and they account for ¾ (3,500 individuals) of the plants! On the opposite end of the spectrum, cacti are the least represented category of Wyoming vegetation; 15 cacti individuals of two species were planted. The prickly pear cacti are in bloom right now - come check it out!
