I have one (G. baueri) since last autumn, it flowered repetitively and now is in resting mode (and a bit shriveling), I am holding my thumbs for it to wake up again rather soon... (or at any time as long as it wakes up...). It is now potted (as it was when I bought it, but if it survives the resting period, I am considering mounting it on a tree (living in Okinawa helps for that).
