I am trying to find a Sedum expert to help figure out better uses for this plant as a green roof material. Can you help point me in the right direction? Also, are there native Sedums?
Here is a list of the books the Miller Library has on this subject, including the following titles:
- Planting green roofs and living walls by Nigel Dunnett and Noel Kingsbury (Timber Press, 2004)
- Ecoroof: questions & answers by Portland Environmental Services (Portland, Or. : Environmental Services, 2004)Note: Portland’s Ecoroof Program is a cooperative effort of the Bureau of Environmental Services and the Office of Sustainable Development. The program promotes ecoroofs by researching ecoroof technologies an providing information and technical assistance to community members.
- Green roofs: their existing status and potential for conserving biodiversity in urban areas by Ecoschemes Ltd (Peterborough: English Nature, 2003)
An article by Jessie Keith from The American Gardener (March/April 2005, pp. 38-41) mentions different types of Sedum appropriate for a green roof, which I will list here:
- Sedum album ‘Coral Carpet’
- Sedum ‘Green Spruce’
- Sedum lydium
- Sedum rupestre (syn. S. reflexum)
- Sedum sexangulare
- Sedum spurium ‘John Creech’
- Sedum telephium ‘Matrona’
You might also want to speak with someone at the Cascade Cactus and Succulent Society of Washington State.
There are some Sedum species native to the Northwest.The Sedums that are native to the Pacific Northwest, according to
The Encyclopedia of Northwest Native Plants for Gardens and Landscapes by Kathleen Robson, (Portland, OR: Timber Press, 2008) include:
- Sedum divergens Cascade stonecrop
- Sedum laxum Roseflower stonecrop
- Sedum oreganum Oregon stonecrop
- Sedum oregonense Creamy stonecrop
- Sedum spathulifolium Broad-leaved stonecrop
- Sedum stenopetalum Wormleaf or narrow-petaled stonecrop
Two additional species are listed in Plants of the Pacific Northwest
Coast, edited by Jim Pojar and Andy MacKinnon (Richmond, WA: Lone Pine Publishing, 1994):
- Sedum integrifolium Roseroot
- Sedum lanceolatum Lance-leaved stonecrop
