Phalaenopsis with Largest Blooms?

[camille1585]

By variety I assume that you mean species?

Many of the large white flowered hybrids have Phal amabilis, philippinensis or aphodite in their ancenstry. Selective breeding then helped create Phals with specific traits, such as very large blooms.

Largest Phal (plant size) is Phal gigantea. Individual leaves can grow to be over 25 inches long.

Floriferous species include Phal schilleriana, some stuartiana, equestris (though flowers are sequential and short lived)
