This residential project is 500 sq.ft of sedum with 2 grasses, sage, rosemary and prickly pear cactus. It was planted with plugs and cutting and took about a year and a half to fill in, and is maturing beautifully. It serves as a laboratory for Green Top and gets plants added and subtracted regularly.
Garden Walkers, here is the plant list for the roof you saw. Thank you very much for visiting during the Buffalo Garden Walk. I hope you enjoyed what you saw!
