Cryptocoryne Wendtii Green (Cryptocoryne wendtii 'Green') — low light, 22-28 °C, pH 6-7.5, no CO2.
Compiled by Aquairi from published sources · Published · Updated
Overview
Cryptocoryne Wendtii Green (Cryptocoryne wendtii 'Green') is a broad-leaved plant of the family Araceae, grown as an aquarium plant. Classic green form of C. wendtii with mid-sized, slightly textured leaves. A workhorse midground plant that tolerates a huge range of water parameters and lighting once established. Ideal for nature aquariums and biotopes.
Taxonomy
- Family: Araceae
- Genus: Cryptocoryne
- Scientific name: Cryptocoryne wendtii 'Green'
- Common synonyms: Crypt Wendtii Green
Habitat
Cryptocoryne species inhabit slow-flowing forest streams, peat-swamp creeks and seasonally flooded lowlands across South and South-East Asia. Most grow rooted in soft mineral or organic sediments under partial shade. In the Aquairi knowledge base this species is recorded from Sri Lanka.
Growth requirements
- Lighting: low
- CO2: not required
- Temperature: 22-28 °C (72-82 °F)
- pH: 6-7.5
- GH: 4-14 °dGH
- Substrate: nutrient-rich aquasoil
- Maximum height: 25 cm
- Growth rate: slow
- Nutrient demand: low
- Recommended placement: midground
Placement
In aquascapes this plant suits the midground. It is planted into a nutrient-rich substrate; emersed-grown stock often melts after submersion and regrows submersed leaves within weeks. Stable parameters minimise repeated melt.
Propagation
This species is spreads vegetatively by runners that form daughter plants on the substrate; clumps are divided once the colony has filled the area.
Common issues
Sudden parameter shifts, particularly temperature drops or large water changes, trigger so-called Crypt melt in which existing leaves dissolve while the rhizome regrows new ones; stable conditions prevent repeat events.
Propagating Cryptocoryne wendtii 'Green': Runners and Rhizome Division
Overview
Cryptocoryne wendtii is native to Sri Lanka and is one of the most robust and easy-to-grow species in the genus Cryptocoryne (family Araceae). The 'Green' form is the classic green selection, very common and widely found in the aquarium trade. Its origin is Asia, growth rate is medium, and it reaches 10-30 cm with rosettes 8-15 cm wide.
It is a rosette plant that grows from a rhizome, not a stem plant, so it is not propagated by topping. It is highly variable under different light and other environmental conditions and works well in the midground.
Propagation Method (Runners / Division)
Cryptocoryne wendtii is propagated by runners. Submerged crypts reproduce vegetatively: the plant sends stolons under the substrate, and each forms a daughter plant with its own roots. A mature clump can also be lifted and its rhizome divided into several independent plants.
Step-by-Step
- Allow the parent rosette to establish and send out runners that form daughter plants in the surrounding substrate.
- Wait until a daughter has its own roots and several leaves before separating it.
- Cut the connecting runner with clean scissors and gently free the daughter from the substrate.
- To multiply faster, lift a mature clump and divide the rhizome into sections, each with roots and leaves.
- Replant daughters or divisions in nutrient-rich substrate, keeping the crown above the substrate surface.
Conditions for Healthy Growth
Light demand is low and CO2 demand is low; the plant thrives in almost all conditions, even in the shadow of larger plants, and tolerates hard water well. As a root feeder it does best in a nutrient-rich substrate. In open space the leaves will virtually lie on the bottom.
Maintenance
Keep parameters stable and avoid unnecessary uprooting. Thin the colony by removing rooted daughter plants when it grows dense. Established clumps need little intervention beyond occasional removal of old outer leaves.
Common Challenges
Leave the rhizome in place; it typically regrows new submersed leaves once conditions stabilise. Hold parameters steady and be patient through the recovery.
