Philodendron patriciae care

Aroids · fussy to keep

Last updated 26 October 2026

Long, narrow, matt dark-green leaves that hang straight down from short stems and turn wavy, almost pleated, as they age — a mature plant is a curtain of them. Described only in 2010, from the Chocó of Colombia. Grow it high up, where the leaves can hang.

Quick facts

Water

Water every 6 days. Water when the top third of the pot is dry. Philodendrons wilt visibly when genuinely thirsty and recover within hours, which makes them easy to read.

Light

Bright indirect light; tolerates a shadier spot than most.

Humidity

Above 70%.

Soil

Loose, airy aroid mix with plenty of bark and perlite.

Feeding

Balanced liquid feed at half strength every third watering through the growing season.

Repotting

Repot once a year.

Toxic to pets

Toxic to cats, dogs and people if chewed — the sap carries insoluble calcium oxalate crystals, which burn the mouth and throat. Keep it off the floor if anything in the house tastes its way through life. The ASPCA lists Philodendron Pertusum (Philodendron spp), the genus as a whole, as toxic to cats and dogs (checked 26 October 2026).

Difficulty

Fussy.

Mature size

Hanging leaves 50 cm to 1 m with age.

Native to

The Chocó region of Colombia.

Watering a Philodendron patriciae

Water every 6 days. Water when the top third of the pot is dry. Philodendrons wilt visibly when genuinely thirsty and recover within hours, which makes them easy to read.

That cadence is the one PlantParlour sets for this species when you name it, and it is deliberately on the cautious side — a plant that asks a day early is safer than one that asks a day late. Log each watering and the reminder moves with the plant rather than with the calendar.

Light

Bright indirect light suits them, and most philodendrons cope with genuinely dim corners better than a monstera will — they just grow slower and stretch. Variegated forms are the exception: white and pink tissue cannot photosynthesise, so those plants need more light than their green siblings, not less.

Humidity and temperature

Above 70%. Central heating in winter is what turns a comfortable room into a dry one, and it is the usual reason an established plant suddenly browns at the edges or picks up spider mites.

Soil and potting

Almost all of them climb or creep rather than sit in deep soil, so the roots want air. Half potting compost, half bark and perlite is the standard recipe. Crawlers like gloriosum want a shallow wide pot rather than a deep one — the rhizome runs along the surface.

Feeding

Balanced liquid feed at half strength every third watering through the growing season. Stop feeding in autumn and start again when you see new growth in spring — feeding a plant that isn't growing just builds up salts in the pot.

Repotting

Repot once a year. Every spring or two, one size up. A philodendron that has filled its pot pushes roots out of the drainage holes and dries out within a day or two of watering — that is the signal.

Common problems

• Long bare stems with leaves far apart

  Too little light. The plant is reaching.

  Fix: Move it brighter and cut the leggy growth back — it will branch from the nodes below the cut.

• Yellow lower leaves

  Usually overwatering; occasionally just age, one leaf at a time.

  Fix: If several go at once, check the roots. Brown and soft means rot; trim them and repot into fresh airy mix.

• Variegation fading back to plain green

  Not enough light for the plant to afford the white tissue.

  Fix: Give it more light, and prune back to a node that still shows variegation — the plant grows on from the last variegated point.

• Brown tips on new leaves that were fine in the old pot

  Low humidity while the leaf was still unfurling.

  Fix: Group plants together or run a humidifier while new leaves open; the damage is cosmetic and permanent on that leaf.

Propagation

Stem cuttings root readily: take a section with at least one node and a leaf, and put it in water, perlite or damp sphagnum. Crawling species are divided instead, by cutting the rhizome between two growth points.

A cutting taken in PlantParlour keeps its link to the plant it came from, so a propagation years later still traces back to the mother plant — which is the point if you ever sell or trade it.

Toxicity and safety

Toxic to cats, dogs and people if chewed — the sap carries insoluble calcium oxalate crystals, which burn the mouth and throat. Keep it off the floor if anything in the house tastes its way through life.

The ASPCA lists Philodendron Pertusum (Philodendron spp), the genus as a whole, as toxic to cats and dogs (checked 26 October 2026).
