Description
Cryptocoryne wendtii ‘Mi Oya’ is another beautiful variety from the group of plants related to C. wendtii, with its reddish-brown well-structured leaves. It is only found in Mi Oya river on Sri Lanka, where the water is very warm. Tropia company was the first aquatic plant nursery to add this plant to their product range and to distribute it commercially. All in all, this species is a variety of C. wendtii that’s not so very common in the hobby.
The cultivation of Cryptocoryne wendtii ‘Mi Oya’ is quite easy. A substrate rich in nutrients enhances growth. Light plays a decisive role in the growth habit of this variety. Lots of light results in a horizontal leaf position, whereas little light prompts C. wendtii ‘Mi Oya’ to grow vertically.
An addition of CO2 is not required. Cryptocoryne wendtii ‘Mi Oya’ does not tend to rot, like so many other representatives of the C. wendtii group.
This species is easy to cultivate emersed. All it needs are a substrate rich in nutrients and a high air humidity. Cryptocoryne wendtii ‘Mi Oya’ adapts quickly from submersed to emersed cultivation.
Propagation is as uncomplicated. Runners provide the keeper with a continually high number of plantlets, which can simply be replanted to the place their keeper wants to cultivate them further.
As one of the largest-growing Cryptocorynes from the wendtii group, Cryptocoryne wendtii ‘Mi Oya’ is best placed in the middleground or in the background of smaller aquaria, where it forms a nice eyecatcher.

Cryptocoryne Wendtii ‘Mi Oya’ Care in Singapore
‘Mi Oya’ brings reddish-brown, well-structured leaves to the wendtii group, originating from a notably warm river in Sri Lanka. That warm-water heritage is a real advantage here: our ambient 27-29C suits it perfectly, so most Singapore hobbyists run it heaterless. Under stronger light the brown tones deepen and the leaf texture stands out more, making it a striking midground choice among driftwood or to break up swathes of plain green planting.
Plant the rhizome at the substrate surface with roots tucked under, and expect the usual crypt melt as it transitions from emersed nursery leaves. Leave it undisturbed through this phase. Like its relatives it feeds heavily from the roots, so a nutrient-rich substrate or root tabs noticeably improves colour and density. Stable water and consistent light bring out its best, while sudden parameter swings can trigger another round of melt.
Our wendtii care guide and root tabs guide cover the details, and you can compare more varieties across our cryptocoryne live plants range.
