These two plants are currently blooming in my greenhouse...
Paph. bellatulum is an old (5 years) plant I have, which blooms regularly and grows very well... every season (since 3 years) it produces up to 5 flowers, however it rarely gets more than one at the same time...

Paph. hirsutissimum... I have this plant since 3 years, and this is the first time it blooms... flower is not very large (9 cm NS)... somehow, I do not get the curve very well with this plant, and in spring it will go back to pine bark medium, as S/H doesn't seem to help much here...
