I am trying to cover a large hillside with a groundcover for sunny sites. I read that sedum acre is aggressive a tolerates hot dry conditions. I bought 60,000 seeds (they're tiny) from a website called outsidepride.com. I have planted them in starter peat pot flats. However, when looking around for growing tips, I have found a few websites that say that this sedum does not grow true to it's cultivar from seed. Is this the case? Has anyone successfully grown it from seed? Thanks.
