Velvet, heart-shaped foliage gives Anthurium ‘Red Crystallinum’ its crystallinum-line look, with warmer red tones appearing in the new growth, veins or petioles. As the leaves harden, the darker blade colour and pale venation become more defined.
This is a foliage Anthurium for warm, bright indoor growing, especially where the soft surface of new leaves can expand without drying too fast. Warm red tones appear most clearly while leaves are young, then the mature blade settles into a darker velvet surface with pale venation.
Young leaves on Anthurium ‘Red Crystallinum’ are the most delicate stage. They expand soft, thin and colour-rich, then gradually harden into darker velvet leaves with clearer venation. Stable moisture and humidity during this phase reduce the chance of stuck, creased or undersized leaves.
The roots need air as much as moisture. A chunky mix keeps oxygen around the roots after watering, which is especially important for velvet Anthuriums that react quickly to compact, wet substrate.
Keep Anthurium ‘Red Crystallinum’ away from pets and small children. Anthuriums contain calcium oxalate crystals, which can cause irritation if plant tissue is chewed and may irritate skin or eyes after sap contact.
The genus name Anthurium comes from Greek words for flower and tail, referring to the spadix. Anthurium crystallinum Linden & André was published in 1873 and is accepted as a species native from Panama to Colombia. The Latin epithet crystallinum means crystal-like or resembling crystal, referring to the pale, glassy-looking vein contrast associated with the species. Anthurium ‘Red Crystallinum’ carries crystallinum-line foliage with red-toned new growth, petioles or veins.
New growth often shows the warmest red tones before the leaf darkens and the pale veins sharpen.
