AI illustration Overview
Cryptocoryne wendtii is the easy 'crypt' - a low rooted rosette in green, bronze or wine-red that, once it stops sulking, is one of the toughest plants in the hobby. Its trademark is 'crypt melt': it dissolves after any big change, then quietly regrows from the roots. (Cryptocoryne wendtii.)
Origin & Natural Habitat
Sri Lanka, on the beds and shaded banks of streams and rivers.
Appearance
Clumping rosettes of textured, wavy-edged leaves 10-20 cm tall; colour shifts from green to bronze-red with more light.
Why People Grow It - Qualities & Benefits
- Very hardy once settled
- Thrives in low light, no CO2
- Colour options from green to red
- Great low midground plant
Care
Light: Low to moderate; more light brings out red tones and keeps it compact.
Water: 22-28°C, pH 6.0-7.5, soft to moderately hard.
Substrate: Rooted feeder - nutrient substrate or root tabs; leave it undisturbed to settle.
CO₂ & feeding: Not needed; grows slowly and steadily without it.
Placement: Foreground to midground clumps.
Extra: Expect 'crypt melt' - the leaves may dissolve after planting or a big water change. Do NOT rip it out. The roots are fine and will push fresh, water-adapted leaves within weeks.
Propagation
Sends up runners with new plantlets around the parent; separate and replant once rooted.
Common Problems & Pests
Crypt melt (transition/instability); slow to establish. Otherwise nearly bulletproof.
Toxicity & Safety
Not on the ASPCA lists. The ASPCA Animal Poison Control Center's plant lists for cats and dogs have no entry for this plant, and we have no other checked source either way. If a pet chews it and seems unwell, call your vet or a pet poison helpline.
Best Suited For
- Beginners (with patience for melt)
- Low-tech midground planting
- Red-tone colour without CO2
- Undisturbed established tanks
FAQ
All the leaves melted after I planted my crypt - did I kill it?
No. Crypt melt is normal after planting or big changes. Leave the roots in place; new submerged leaves regrow in a few weeks.
How do I get the red colour?
More light. In low light C. wendtii stays green; brighter light brings out the bronze and wine tones.
