i used to use roseflora. i found their website, but you couldn't actually order it. i called, and was told they have a similar product. see http://www.better-flora.com/Mity%20Gro.htm
i was actually only interested in roseflora again because messenger brand harpin is out of commerce. i eventually found that gardensalive.com is selling a harpin product.
hope that helps.

Here is a link that might be useful: source of current version of roseflora
