Prairie Smoke (Geum triflorum) has +r <br /> beautiful smokey red flowers which bloom ` <br /> April to June and reaches about a half- <br /> foot in height.6 <br /> r <br /> Although native plants are not as ideal as many succulents and need more water <br /> and maintenance (keeping in mind that succulents need almost no water), this list <br /> provides a good native alternative to our Elk River partners from the boring sedum <br /> beds. Keep in mind there are many more native plants suitable to green roof conditions, <br /> these listed are simply the plants we think would work best at Elk River. Native plants <br /> have recently begun to be grown with more success on Minnesota green roofs. In 2009 <br /> the Target Center received a green roof with 16 different species native to Minnesota <br /> prairie bluffs. The Minneapolis Library and St. Paul Fire Station Headquarters also have <br /> green roofs with native plants.2 We recommend a mix of the two; the native plants, <br /> especially the field pussytoes and the prairie smoke, with a nice "mat" cover of sedum to <br /> fill in gaps and limit water needs. <br /> Can we set up the green roof ourselves? <br /> Green roof self-installation is definitely a possibility. After the materials are <br /> obtained from a green roof supplier, the roof can be installed by people on site, ensuring <br /> that the installers are using proper safety techniques. According to The Minnesota <br /> Occupational Safety and Health Act (MNOSHA), all personnel participating in roof <br /> installation must use a harness to ensure that no one falls from the roof.' The other <br /> option would be contacting contractors that could help obtain materials and install <br /> themselves. These contractors would be recommended or contracted by the green roof <br /> suppliers. Most of the people we contacted suggested using LiveRoof® for roof supplies <br /> and help with installation. LiveRoof is especially useful as they can come to the roof site <br /> and make an installation grid that fits the need of that roof, then provide their signature <br /> "trays" that they install themselves. LiveRoof claims on their website several other <br /> advantages, including: <br /> • Adds only 10-12 lbs extra weight per ft2 <br /> • Certified for green roof installation <br /> • Installation Experience <br /> • You have someone to carry the warranty <br /> 7 <br />
