Anthurium regale × magnificum

Peruvian and Colombian giants brought together

This cultivated cross combines Anthurium regale from humid terrestrial forest around Peru’s Huallaga drainage with Anthurium magnificum from wet foothill and intermediate-elevation forest in Colombia. The hybrid joins two large Andean velvet-leaf lineages under cultivation, where seedlings may differ in vein contrast, petiole form and mature scale.

Growing Anthurium indoors

• Humidity and airflow: Maintain high humidity for the large developing blades, balanced by gentle air movement around the plant. Let wet foliage dry quickly.
• Watering: Water after a definite dry-down in the upper part of the root ball, reaching every side of the pot before letting all excess drain from the coarse mix.
• Temperature: Stable indoor warmth suits Anthurium regale × magnificum; avoid cold root conditions and sustained heat around the large leaves.
• Substrate and repotting: Let Anthurium regale × magnificum settle in the original container first, using pot weight, root activity and clean new growth through the well-aerated root zone and emerging foliage to decide when a later repot will cause the least disruption. Afterwards, use a slightly larger pot with fine bark, coco coir, chopped coco husk and pumice or perlite.
• Leaf care and propagation: Stabilise the pot early and keep expanding leaves away from walls and neighbouring plants. Brush mature foliage dry and propagate from rooted offsets or node-bearing stem sections.

When Anthurium regale × magnificum needs attention

• Yellowing linked to moisture: Flexible leaves paired with low pot weight show that moisture has run short; give one complete soak and keep the drainage path clear. Persistent pot weight with a damp centre points to lost air around the roots; pause the routine and examine the roots before adding more water. A lone oldest leaf may yellow naturally while the rest stays firm.
• Firm roots versus hollow roots: A firm cream or tan root remains useful; fresh tips provide an extra sign of activity. Remove failed root sections once their slippery or hollow texture is clear; use a ventilated pot sized to the surviving roots and a fine open substrate.
• A dark patch that changes size: A mark caused by handling usually stops changing once the leaf hardens; movement at the edge would point to a different problem. An expanding damp lesion needs attention as soon as its border moves; move the plant away from others.
• Brown margins after a dry cycle: Low humidity can sharpen damage caused by an uneven watering cycle; check which condition changed before the mark appeared. Check the centre of the mix as well as the surface; correct dryness first, then address salts or heat only if browning continues.

Anthurium regale × magnificum is toxic to people and pets

• Keep this plant away from children, cats and dogs.
• Its leaves and stems contain insoluble calcium oxalate crystals, which can irritate the mouth, throat, skin and eyes.
• Chewing may cause burning pain, drooling, swelling, vomiting or difficulty swallowing. Contact a veterinarian or medical professional after exposure, especially if swelling or breathing problems occur.

Where do the names Anthurium regale and Anthurium magnificum come from?

The genus name Anthurium combines Greek anthos, “flower”, and oura, “tail”, referring to the tail-like spadix. The epithet regale is Latin for royal. The epithet magnificum is Latin for magnificent.

Heinrich Wilhelm Schott established the genus Anthurium in 1829 in Wiener Zeitschrift für Kunst, Literatur, Theater und Mode, volume 3, page 828.

Jean Jules Linden first described Anthurium regale in 1866 in La Belgique Horticole, volume 16, page 200.

Jean Jules Linden first described Anthurium magnificum in 1865 in Catalogue des Plantes Exotiques, volume 19, page 2.
