question: most floriferous

[Leafmite]

Dendrobium auriculatum blooms all the time. They do not form spikes, just buds off the stem of the plant but the flowers are pretty and fragrant. Not only is it nearly always in bloom, it is easy to grow and the leaves are pretty, almost like a fern.

Phal-type Dendrobians if you are willing to be patient for a year or two while they get established in a medium that does not decay. Once their roots are established and happy, they can be in bloom ten months out of the year. I have a Dendrobium Classic Gem 'BFC' that has already bloomed four times since November. The blooms are long-lasting (but peloric, which I really do not like).

There are quite a few options from The Pleurothallid Alliance that can be in bloom all the time under the right conditions. I am sure that Ecuagenera or Andy of Andy's orchids could recommend some good ones.
