Mini orchid- B. hirundinis or B. purpurascens?

[epiphyte_neophyte]

Hello! I have a small, warm/intermediate terrarium and I am trying to decide between Bulbophyllum hirundinis and B. purpurascens. Can someone share their opinion on which is more floriferous, easier, more compact, etc.? I have a B. tingabarinum in the terrarium which is doing great and flowering. Tell me which one is worth getting! Attached is a picture of a bud on my Bulbophyllum tingabarinum in the small terrarium. Other plants are:

Haraella retrocalla (in bud)
Lepanthes telipogoniflora
Lepanthes calodictyon (in flower)
Bulbophyllum tingabarinum (in bud)
Macodes petola
Sinningia pusilla (sprouts in the front)

Sorry the picture is upside down- i tried a few uploads but it seems to come up this way.

Oy I have figured out I have to take the pictures with my phone side ways to make the pictures actually show up correctly.

Can't help you but it looks very neat.

I have a Bulb purpurascens and it is a nice tight clumper but it needs to have several pbulbs before it blooms. It does have very pretty dark foliage with a hint of purple on the small leaves.

Sorry I've never had the other Bulbo.

Though both species are what I would call miniature, hirundinis is vegetatively about 1/2-1/3 the size of purpurascens, with more colorful and proportionately larger flowers (but plainer foliage). hirundinis does best for me in intermediate or cooler temperatures whereas my purp died when I let night temps drop below 55 F, so purpurascens may be better suited for the temp range of your tank.
