Cryptocoryne Wendtii Varieties Compared: Green, Brown, Red and Tropica
No planted tank collection is complete without at least one Cryptocoryne wendtii. It is the workhorse of the aquascaping world: undemanding, attractive and available in a surprising range of colour forms. This cryptocoryne wendtii varieties comparison guide from Gensou Aquascaping at 5 Everton Park, Singapore helps you distinguish between the main cultivars and choose the right one for your layout.
A Brief History of Cryptocoryne Wendtii
Cryptocoryne wendtii originates from Sri Lanka, where it grows along riverbanks and in seasonally flooded forests. It was first described in 1958 and quickly became one of the most popular aquarium plants worldwide. Decades of cultivation have produced numerous colour variants, some occurring naturally and others selected by nurseries. Today it remains one of the top-selling aquatic plants in Southeast Asia.
Green Wendtii
The green form is the most widely available and affordable variety, typically costing $3-$5 per pot in Singapore. Leaves are a bright olive-green with slightly ruffled edges, growing 10-15 cm tall under moderate light. It is exceptionally hardy, tolerating low light, no CO2 and a wide range of water parameters. This is the variety to start with if you have never kept crypts before.
Under higher light, green wendtii develops a more compact growth habit with shorter petioles and wider leaves. It makes an excellent midground plant in tanks of 30 cm height or taller.
Brown Wendtii
Brown wendtii produces leaves in shades of bronze, copper and dark olive, sometimes with reddish undertones. It grows slightly larger than the green form, reaching 15-20 cm in mature specimens. The colour intensifies under moderate to high light and iron-rich fertilisation. In low-light setups, it tends to revert toward a dark green-brown that lacks the warm bronze tones.
This variety pairs beautifully with bright green foreground plants like Eleocharis or Marsilea, creating natural colour contrast without resorting to demanding red stem plants.
Red Wendtii
Red wendtii displays leaves ranging from deep burgundy to wine-red, particularly along the undersides and margins. New growth often emerges copper-pink before darkening. It reaches 12-18 cm and responds well to iron supplementation, which deepens the red colouration. Without adequate iron, the red fades to a brownish hue that looks underwhelming.
Position red wendtii where it catches direct light. Shaded specimens lose their red colouration significantly. Combining red wendtii with green wendtii in alternating groups creates a striking effect in the midground.
Tropica Wendtii
The Tropica variety, named after the Danish aquatic plant nursery that popularised it, is the most compact cultivar. It grows just 8-12 cm tall with broad, hammered leaves in dark bronze-green. The leaf texture is distinctly more ruffled and puckered than other wendtii forms. Tropica wendtii works exceptionally well as a foreground-to-midground transition plant in smaller tanks.
It demands slightly more light than the green variety to maintain its compact form. Under very low light, it stretches upward and loses the characteristic broad, textured leaf shape.
Growing Conditions for All Varieties
All C. wendtii varieties share similar care requirements. They prefer pH 6.0-7.5, GH 3-12, KH 2-8 and temperature 22-28 degrees C. Singapore’s water conditions suit them perfectly. Plant them in a nutrient-rich substrate; root tabs or aquasoil dramatically improves growth compared to inert gravel. Liquid fertiliser supplements iron and micronutrients but cannot replace substrate nutrition for these heavy root feeders.
CO2 injection is not required but accelerates growth and improves colour. Without CO2, expect a new leaf every one to two weeks per plant. With CO2, that pace doubles.
Dealing With Crypt Melt
Nearly every newly planted crypt experiences some degree of melt, where existing leaves turn brown, become translucent and disintegrate. This is a stress response to changed conditions, not a death sentence. Leave the roots and crown undisturbed in the substrate. New leaves adapted to your tank conditions will emerge within two to four weeks. Removing melted leaves prematurely by uprooting the plant often kills it entirely.
Crypts purchased in tissue culture cups tend to melt less severely than pot-grown specimens, as they have fewer leaves adapted to emersed growth. Tissue culture plants from local suppliers typically cost $5-$8 per cup on Shopee.
Choosing the Right Variety for Your Aquascape
For a natural, jungle-style layout, mix green and brown wendtii in irregular clusters. For a more structured Dutch-style design, plant each variety in distinct groups separated by contrasting species. Use Tropica wendtii in nano tanks or as a transition between foreground carpet and taller midground plants. Red wendtii works as an accent, drawing the eye to specific focal points in the layout. All four varieties are readily available in Singapore’s aquatic plant shops and online marketplaces.
