Choosing the correct plant type is the first step to a successful vegetated roof. It is important to note your USDA plant zone, sun exposures of the planting area, potential wind exposures, irrigation logistics, and the pitch/slope of the roof. Time frames and maintenance burden are also key items to consider. Based on these plant characteristics, the correct plant palette can then be chosen. Hanging Gardens offers plant material for all vegetative roofing projects, regardless of their idiosyncrasies. We offer sedum cuttings, perennial plug varieties, fully vegetated sedum blankets, tiles and fully vegetated modules.
