Re blue noid phal: I seem to remember something about pulcherima (which is in a lot of the blue phals) forming a distinct 'ring' of growth each year? So the fast growth and die back might be natural? Hope so: my Purple Martin is acting a bit like that, though not to that extent.
Lily of the Valley: don't know if it's the same plant (the Pilgrims seemed to name a lot of things after things they remembered from the old country!), but we used to have what we called that growing pretty much wild in my garden when I was a kid: that was in Cheshire, UK. Cheshire's one of the wettest parts of the UK, climate not extreme, but does get freezing weather in the winter. Soil was sandy, black in colour. Position light shade.
I have loads of stuff struggling a bit. I have a bad habit of trying lots of things and not really sorting out what they need! I lose a few but it's great when I do get it right in the end!
I just won a phal equestris keiki in my orchid group raffle last saturday. Totally shriveled! I'm keeping it bare root at the moment and wetting the roots every time they go to silver, which is several times a day at the moment! A couple of it's leaves are plumping up, the other two are gone I think.
A stuartiania var nobilis I bought in flower went downhill afterwards and I'm not sure it's got much in the way of roots: lots of dead ones! But it's just started a new one so I'm hoping!
On the other hand I just lost my zygo triste I think
Accidentaly snapped off a new growth and next thing I know it's other new growth is rotting from the centre and other pulbs rotting. Not checked the pot for survival yet (it's a plant that grows it's pulbs partly underground) but I think it's gone.
