In short

Anthurium faustomirandae, sold as Fausto Miranda's Anthurium, is a member of the largest aroid genus and a Neotropical epiphyte or terrestrial rainforest plant. A Mexican species named for the botanist Faustino Miranda, with very large arrow-shaped leaves up to a metre long on robust upright petioles, sometimes grown as a statement floor plant. Like most Anthurium, it needs bright filtered light, a chunky free-draining aroid mix, and humidity above 60 percent — the leaf surfaces brown and curl in dry indoor air.

Overview

Anthurium faustomirandae is one of about 1,000 species in Anthurium, the largest genus in the aroid family Araceae. A Mexican species named for the botanist Faustino Miranda, with very large arrow-shaped leaves up to a metre long on robust upright petioles, sometimes grown as a statement floor plant. Most Anthurium are epiphytes or hemi-epiphytes in their native rainforest, which is why they need open chunky mixes rather than dense potting soil.

Care Priorities

  • Bright filtered light, never direct midday sun.
  • Use a chunky aroid mix — orchid bark, perlite, coco coir.
  • Water thoroughly when the top 2 to 3 cm of mix is dry; let excess drain.
  • Humidity above 60 percent — group with other tropicals or use a humidifier.
  • Provide a moss pole for climbing species; terrestrial species are fine in pots.

Common Problems

Yellow lower leaves with mushy stems mean overwatering or compacted mix — repot into chunky aroid mix. Brown crispy edges signal dry air or fluoride-heavy tap water. Webbing under leaves is spider mites; rinse the foliage and treat with insecticidal soap.

Frequently asked questions

How big does Anthurium faustomirandae get indoors?

Mature indoor specimens reach 1 to 1.5 m tall with leaves up to 90 cm long. Provide a heavy pot, chunky mix, and floor space — this is not a tabletop plant.

What soil mix should I use for Anthurium?

A chunky aroid mix works best — roughly equal parts orchid bark, perlite or pumice, and coco coir or peat. Standard potting soil compacts and holds water around the roots, which causes the rot Anthurium are notorious for.

Is Anthurium toxic to pets?

Yes — all Anthurium contain calcium oxalate crystals and are listed as toxic to cats and dogs by the ASPCA. Ingestion causes oral burning, drooling, and vomiting. Keep out of reach of pets that chew leaves.
