Propagating Cryptocoryne 'Flamingo': The Pink Crypt by Runners

How to propagate the demanding pink Cryptocoryne wendtii 'Flamingo' by runners and rhizome division, why its pink leaves grow slowly, and how to handle crypt melt.

Overview

'Flamingo' is a pink-leaved cultivar of Cryptocoryne wendtii, a very variable rosette species native to Sri Lanka and one of the most robust and widely traded crypts. The wild species is propagated by runners; the cultivar keeps that habit. Its signature pink tissue lacks chlorophyll, so it photosynthesizes poorly and grows noticeably slower than the green wendtii forms, demanding strong light to hold its color.

Propagation Method (Runners / Division)

Like its parent C. wendtii, 'Flamingo' reproduces vegetatively underwater by sending out runners (stolons) through the substrate, each ending in a daughter plantlet. A well-grown clump can also be divided at the rhizome. Expect both methods to be slow, because the low-chlorophyll pink leaves limit how much energy the plant can store.

Step-by-Step

1. Grow the mother plant under strong light until it is firmly rooted and producing healthy pink leaves.
2. Wait for runners to appear and let each daughter plantlet develop several leaves and its own roots before separating it.
3. Cut the runner cleanly between mother and daughter, or lift and divide the rhizome into rooted sections.
4. Plant each piece in rich aquasoil, burying the roots but keeping the crown clear of the substrate.
5. Provide bright light and stable CO2-enriched conditions so the pink coloration returns.
6. Leave the plantlets undisturbed for about 30 days to root in.

Conditions for Healthy Growth

Because the pink pigment masks chlorophyll, 'Flamingo' needs strong light, added CO2, and a rich aquasoil to keep its color and grow at a usable pace; under weak light it slows further and can revert toward green. As a root feeder it relies on a nutrient-rich substrate. Lighting strongly influences the appearance of wendtii forms, so light intensity is the key lever for this cultivar.

Maintenance

Trim away melted or faded outer leaves at the base and harvest runners to keep the clump tidy. Keep parameters constant; this demanding cultivar reacts poorly to swings in light, CO2, or water chemistry.

Common Challenges

Crypts adapt poorly to transplantation and may need about 30 days to settle, and the low-chlorophyll pink leaves make recovery slower than for green crypts. Patience and a mature, stable tank give the best results.
