Cryptocoryne spec. 'Flamingo'

Geographical Origin and Habitat: Cryptocoryne spec. 'Flamingo' is a cultivar selected in vitro and propagated under submersed greenhouse conditions; it does not exist in the wild. However, the parent species from which it mutated is native to Sri Lanka, where it colonizes shaded stream beds rich in organic matter and minerals. The 'Flamingo' selection was isolated due to its extraordinary

Color & Texture: mutation that partially inhibits chlorophyll, allowing pink anthocyanin pigments to dominate.

Taxonomy & Genetics: It belongs to the Araceae family, genus Cryptocoryne. It is considered a stable and patented mutation of Cryptocoryne wendtii (or related species). Genetically, the stability of the pink coloration is strictly linked to strong light stimuli and a constant supply of nutrients; under insufficient light, the plant can regress, producing dull green leaves.

Physical Structure: It develops compact and low rosettes, reaching an average height of 5-10 cm. The leaves are lanceolate or slightly ovate, with flexible petioles growing inclined relative to the substrate. The root system, though originating from tissue culture, is capable of developing vigorously, forming strong fibrous roots and lateral runners.

Color & Texture: The absolute highlight is the leaf coloration, which varies from pale pink to baby pink or intense magenta and cherry red under intense lighting. The lower page retains purple hues. The leaf texture is smooth, slightly glossy, with wavy margins that add a dynamic look to the rosette.

Lighting & CO2: Requires medium-high to high lighting. Without adequate light, the plant loses its characteristic pink color, shifting to green-brown. Constant CO2 injection is highly recommended to support its delicate metabolism and promote steady, compact growth.

Nutrition & Substrate: An active and fertilized fine-grain substrate is essential. It requires abundant iron-based root fertilization to stimulate and maintain the pink pigmentation. A balanced liquid column fertilization prevents chlorosis and foliage decay.

Water Chemistry: Prefers soft to moderately hard water with a KH between 2 and 8 dKH and a stable pH between 6.0 and 7.2. It is particularly sensitive to nitrogenous waste accumulation and sudden shifts in chemical parameters. Optimal temperature is between 20°C and 28°C.

Space Management & Placement: Place in the foreground or front midground, preferably in a central or prominent position to utilize its strong color contrast. Plant individual crowns spaced 2 cm apart. Do not place it under the shadow of larger plants.

Pruning: Pruning consists of removing older outer leaves showing signs of yellowing or algae. Cut the leaf near the crown using sharp aquascaping scissors, avoiding pulling petioles by hand to prevent pulling the plant from the soil.

Risks & Diseases: It is considered one of the most delicate Cryptocorynes and is highly prone to "Cryptocoryne melt." Any sudden variation in water changes or lighting can trigger leaf decay. Absolute stability is recommended.
