Philodendron gloriosum
Colombia (POWO); often also reported from Central America to Venezuela in horticultural sources
First described by André.
Large, velvety (velutinous), heart-shaped leaves with striking pale silvery-white veins and pink-tinged margins; emergent leaves brightest.
Terrestrial crawler: the rhizome grows horizontally across the soil surface rather than climbing; grow in a long, shallow planter.
Genus from Greek 'philo' (love) + 'dendron' (tree), referring to many species' habit of climbing trees. Epithet 'gloriosum' means 'glorious/splendid', for the velvety, silver-veined foliage.
Philodendron gloriosum was described by André; POWO gives its native range as Colombia, though horticultural sources frequently extend it through Central America to Venezuela. Unlike most climbing philodendrons it is a 'crawler' — its thick rhizome creeps horizontally along the ground, sending up large, velvety, heart-shaped leaves veined in pale silvery-white.
Because it crawls, grow gloriosum in a wide, shallow pot or trough so the rhizome can spread horizontally; keep the rhizome at the surface, not buried. Bright indirect light, an airy moisture-retentive mix, and high humidity give the best velvet and veining. Water when the top 2–3 cm dries; avoid soggy soil.
Chunky, moisture-retentive aroid mix (40% orchid bark, 30% coco coir, 20% perlite, 10% charcoal). Use a long, shallow planter; lay the rhizome on top with the growing tip pointing into open space.
Monthly during growing season (spring–summer)
- Rhizome/root rot if buried or overwatered; spider mites in low humidity; brown crispy edges from dry air or hard water; slow recovery if disturbed too often.
- Unlike most houseplant philodendrons, gloriosum is a 'crawler' — its rhizome creeps across the ground rather than climbing.
- Its velvety leaves with bright white veins make it one of the most coveted foliage philodendrons.
- Because the rhizome grows sideways, it's best displayed in a long, shallow planter.
