Largest = Grammatophyllum speciosum

Smallest = Platystele jungermannioides

Someone correct me if I'm wrong.

Is Grammatophyllum the biggest flower or the biggest plant?

I always thought Sobralia was bigger flowers.

>> Largest = Grammatophyllum speciosum
That plant appears to be a vandaceous variety. If each individual flower is the biggest flower, then those spikes would be MASSIVE.

There is a record for Paphiopediluum sanderianum being the "biggest" flower, but in my opinion it is cheating lol. It appears to be a regular sized flower with an insanely long "tail".

I was thinking more along the lines of the overall proportion of the flower.

There appears to be a consensus on the Platystele jungermannioides being the smallest flower though.

Thanks for the info.

The Biggest Orchid in Record is a Blc. "Brassolaeliocattleya Hybrid" , . . .

The Biggest Plant is Grammatophyllum speciosum but also the biggest flower spike.

sorry and the biggest orchid flower species is Cattleya warscewiczii
