Anthurium crystallinum 'Red Crystallinum'
Cultivated/collector form; do not assign a wild range.
Crystallinum-type velvet leaves with red to bronze emergent growth or red-toned venation/petioles, fading or intensifying depending on line and conditions.
Upright velvet Anthurium grown for colourful emergents and contrast rather than formal botanical identity.
Trade name refers to red emergent leaves, petioles, or venation in crystallinum-type plants.
“Red crystallinum” is used inconsistently for forms, lines, and hybrids. Collector_form is safer than cultivar unless a named clone/line is documented.
Provide bright filtered light to support colour without burning leaves. Keep warm and humid with consistent moisture in airy media.
Use a chunky aroid mix with bark, perlite/pumice, coco chips or coarse fibre, and a moisture-retentive component. Repot gently when roots fill the pot.
Monthly at quarter to half strength during active growth. Flush occasionally if using mineral fertiliser.
- Root rot in dense media; leaf edge burn from low humidity, salts, or inconsistent watering; spider mites, thrips, scale, or mealybug; cold damage in cool indoor conditions.
- Red emergent colour alone is not enough to prove a distinct cultivar or hybrid identity.
