Pleione formosana and their unfortunate demise

We also got these at the Venice Orchid Show in February 2013, but they didn't survive. We got three "nuggets" as I was calling them. We had read about them in an old issue of the AOS magazine, and thought they were really cool and lovely. We were so excited to find them. We planted them in a 1" deep maybe 5" round saucer like pot with holes in the bottom. We filled it with sphagnum and tucked the nuggets about half way into the moss. We kept the moss evenly moist. The nuggets started growing right away. Two of them made growths out the side that turned into flowering spikes, and one of them made leaves out the top center of the nugget and didn't flower. The flowers were beautiful and lasted a week or two. The nuggets then started making leaves out the sides like they were making a new pseudobulb, and the other one made leaves and roots from the top of the nugget. The leaves seemed to be doing well at first, but then they started to look a little shrively. We read about them some more that they grow on rocks with humus like leaf litter in cool temperate forests. We tried to take the nuggets out and mix perlite in with the moss to give more drainage. We didn't realize there were so many roots in the medium, so that really disturbed them and they did not like that at all. That, I think, pretty much spelled their doom. The nuggets were kind of rotting and it just got worse and worse until the leaves were totally shriveled and the nuggets were totally rotten. We had to throw it all away by the end of May when we moved to Chicago. We still aren't really sure what exactly went wrong. We think it just needed more drainage. We think if we ever plant them again we will do a similar pot with some stones and try to get some leaf litter humus from the woods to put around the rocks.
