Hi,

I don't have any experience with this species directly, but there are a lot
of Bulb. species that only open up fully at certain times of the day,
usually in the morning.

Bulb. pardolatum is one:

I can never get a photo of this species fully open because by the time I get
to the OrchidMania greenhouse on Sundays, it's about 11am and the darn thing
has closed up like that again.

Good luck!

hi there everyone,
does anybody know about the behavior of bulb. masdevalliaceum. i just
bought one today, and now it has closed up but doesnt appear to be
wilting. does it close up at night or during cold weather? i would hate
to think that i am already doing something wrong?
