Griffinia liboniana is free flowering and if well grown can bloom several times a year. G. liboniana likes a very organic mix that drains fairly well but it's important that the medium is kept moist as the plants can decline quite fast if left to dry for a period of time. The medium should feel like a well wrung sponge with just a hint of moisture. Some grow Griffinia species in pure Sphagnum Moss while I grow mine in a Sphagnum/Bark/Perlite mixture at even parts.
Griffinia species grow amongst the forest floor which is littered with plant debris and handles very low light levels making it a prime candidate for houseplant culture. Sadly Griffinia aren't too common in cultivation but with recent breeding work by Kevin Preuss hopefully this changes in the future.
