Cryptocoryne Ciliata care guide
Cryptocoryne Ciliata (Cryptocoryne ciliata) — medium light, 24-29 °C, pH 6.5-8, no CO2.
Compiled by Aquairi from published sources · Published · Updated
Overview
Cryptocoryne Ciliata (Cryptocoryne ciliata) is a broad-leaved plant of the family Araceae, grown as an aquarium plant. Large brackish-tolerant crypt that grows tall, rosette-shaped clumps. Native to mangrove estuaries; can be kept in fresh water but truly thrives in slightly brackish setups (1-5 ppt).
Taxonomy
- Family: Araceae
- Genus: Cryptocoryne
- Scientific name: Cryptocoryne ciliata
- Common synonyms: Hairy Crypt
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 South-East Asia.
Growth requirements
- Lighting: medium
- CO2: not required
- Temperature: 24-29 °C (75-84 °F)
- pH: 6.5-8
- GH: 6-20 °dGH
- Substrate: nutrient-rich aquasoil
- Maximum height: 40 cm
- Growth rate: medium
- Nutrient demand: medium
- Recommended placement: background
Placement
In aquascapes this plant suits the background. 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 ciliata var. latifolia
Overview
Cryptocoryne ciliata var. latifolia is the broad-leaved form of C. ciliata, a large crypt and one of the few aquarium plants that tolerates salt. C. ciliata grows across India, Bangladesh, Indochina, Malaysia, Indonesia, New Guinea and the Philippines, and is found in semi-brackish water in some areas. Unusually for a crypt, it can be multiplied by true seeds in addition to vegetative means.
Propagation Method (Runners / Division / Seeds)
Submerged crypts reproduce vegetatively, mainly through stolons: runners that creep through the substrate and raise daughter plants. An established rhizome can also be divided into rooted sections. When grown emersed it may flower via a spadix enclosed in a spathe and reproduce sexually, so C. ciliata can additionally be raised from true seeds.
Step-by-Step
- Grow the parent strongly, optionally emersed, to encourage runners or flowering.
- For runners, expose the stolon and wait until each daughter has leaves and roots before cutting it free.
- For division, split the rhizome so every section keeps roots and a growing crown.
- For seeds, let an emersed plant flower and set seed, then sow into damp nutrient-rich substrate.
- Replant divisions and rooted daughters at their original depth.
- Keep new plants in stable, optionally slightly brackish, conditions to settle in.
Conditions for Healthy Growth
This is a large background crypt that handles medium light, warm tropical temperatures, harder water and even slightly brackish conditions over a nutrient-rich substrate. As a root feeder it relies on a rich bottom and root tabs; CO2 is not required. Its salt tolerance sets it apart from most crypts.
Maintenance
Give it room for its large leaves, keep parameters stable, replenish substrate nutrients and remove decayed foliage. If kept brackish, change salinity only gradually to avoid stressing the rhizome.
Common Challenges
Hold conditions steady and a melted plant regrows from the rhizome. Its large size demands space, and sudden swings in salinity or other parameters are the other things to watch.
Propagating Cryptocoryne ciliata: Runners, Division and Seeds
Overview
Cryptocoryne ciliata is a large rosette crypt of the family Araceae, notable as one of the few aquarium plants that tolerates semi-brackish water and is listed among brackish aquarium plant species. It grows as a clump of tall leaves from a creeping rhizome, so it is propagated vegetatively, not by cuttings.
Propagation Method (Runners / Division)
Ciliata offers three routes. Most reliably it spreads by runners (stolons) that carry daughter rosettes, and an established clump can be lifted and divided at the rhizome. Unusually for the genus, emersed plants flower readily and can set true seeds, giving a sexual route in addition to vegetative spread.
- Runners (stolons): daughter rosettes form along the rhizome.
- Rhizome division: split a mature clump into rooted sections.
- Seeds: emersed flowering plants can produce true seeds.
Step-by-Step
- Let the parent develop several daughter rosettes on runners or grow into a wide clump.
- Ease the rhizome partly out of the substrate to expose runners and growing points.
- Separate a rooted daughter rosette, or cut the rhizome into sections that each carry leaves and roots.
- For seeds, grow plants emersed so they can flower; collect ripened seed once a flower has set.
- Replant divisions with the rhizome at the surface and only the roots buried, then leave them undisturbed.
Conditions for Healthy Growth
Ciliata grows in fresh water but truly thrives in slightly brackish setups, reflecting its mangrove-estuary origins. The broader Cryptocoryne genus tolerates roughly 12-33 C and neutral to slightly alkaline water. As a heavy root feeder it wants a nutrient-rich substrate, and it is commonly grown emersed before submersion.
Maintenance
This is a tall background plant, so give it room. Remove melted or yellowing outer leaves, keep the rhizome at the substrate surface, and thin daughter rosettes once a clump becomes crowded.
Common Challenges
Crypt melt is the first thing to expect: after transplanting or a rapid change in conditions a newly planted crypt may shed all of its leaves. This is normal, the rhizome usually survives, and fresh leaves typically appear within about a month. With ciliata, abrupt changes in salinity are an extra trigger to avoid.
