Best Tall Sedum?
Comments (4)Maybe it depends on what you mean by "best". If you're hoping for a plant that really does well all year in your California climate, the "tall sedums" of back east aren't your "best" bet. The two common eastern types, S. telphium and S. spectabile, aren't dependable in most gardens. I have seen a few nice ones but none compare to their beauty in midwestrn and eastern gardens. We have plenty of tall sedums that are almost "California signature" plants, doing extraordinarily well here: Sedum 'Black Jack' Sedum 'Postman's Pride' Sedum 'Purple Emperor' Sedum 'Samuel Oliphant' Sedum dendroideum, S. praealtum Sedum oxypetalum If you're interested in a tall succulent, you might also look at the flowering Kalanchoes and Cotyledons. Do you know what Sunset Western Garden Book zone you're in? Joe...See MoreWhat is the best sedum species for a greenroof?
Comments (5)Thanks for the replies. First some specs. I have a brand new epdm roof with a 1% grade and is 800 sq ft. It gets mainly full sun and has a commercial size gutter on one side. Some of the ideas I have been kicking around are to use a product called versicell which are interlocking polyethylene panels with moulded studs on it and will be placed directly over the top of the epdm. The product is mainly used on the outside of foundation walls to provide a drainage space but is also sold for greenroof applications. On top of this I will place 4'x4' bags of 80% inorganic material i.e. expanded shale, clay or slate, what ever is cheap and available, and the rest manure. The bags will be made by folding over a sheet dupont's pro landscape fabric and sewing around the edges. The growth medium could be mixed in a concrete mixer. The landscape fabric is $42 dollars for a 4'x 100' ft. roll and that would make appox. 10 bags which would cover say 160 sq. ft. So say maybe 5 rolls which would be $210. If each bag is 3 inches thick than every four bags would be 16 sq. ft. of soil medium. What that would cost I still have to figure out. I just place an order for 30 sheets of rockwool , $168, each sheet has 98 cells. I planning to start at least at least 8 of those on the roof with sedum seeds. They will be placed in 10x20 trays with plastic domes and I would assume take at least a 1 year to get to the planting stage. So you could figure thats $45 in rockwool and at least $15 in seeds matter what I get. This is all a work in progress and I would appreciate any suggestion and or corrections in this one of my latest porjects....See MoreSoil for Sedum
Comments (1)Any kind of soil will work - cheaper the better :-) Sedum only needs good drainage. Bagged topsoil from your local home improvement store should be just about perfect....See MoreSoil for Sedum's
Comments (1)Potting soil will work if amended to increase drainage. The addition of crushed granite, pumice or a product called "dry stall" (or whatever equivalent the feed stores carry) will work. The people in the c&s forum love this formula called "gritty mix" but keep in mind many are growing in containers in colder climates. Just increase drainage and monitor your watering until sedums are established, then you can slack off. Sedums are really fairly tolerant plants IMO. -Ming...See Moreponderinstuff
