Though Cryptocoryne auriculata is well known from literature and is quite
often imported to Europe, the plant proved to be very difficult to cultivate. There are
very few reports on the flowering of this species. After a short time the species fades
away from cultivation. In nature, C. auriculata grows between stones (see the
whitish lower part of the petioles in the pictures at top), what indicates that the water
is running fast in the rainy season
