The flowers of the species are large and showy, often produced on bare parts of the stem. The underside of the leaves are sometimes a nice red or marked with red veins, making an overall favorable impression when flowering and viewed from underneath.

N. flumensis grows horizontally, and in a basket can easily become more than a meter across. The plant featured above was exhibited in the 2021 virtual show of the Gesneriad Society.
