Heartleaf Philodendron Care: The Vining Philodendron, Not Split-Leaf

Philodendron hederaceum is the trailing, heart-shaped-leaf vine that gets sold in hanging baskets next to pothos at every garden center. It tolerates low light, forgives missed waterings, and looks generous and lush within months. It's toxic to cats and dogs per the ASPCA — keep it out of reach of pets that chew.

What it is

The accepted scientific name is Philodendron hederaceum (Jacq.) Schott per Kew POWO. You'll see Philodendron scandens on older labels — that's a synonym per MBG, not a different species.

Family: Araceae. Native range is Mexico through tropical America, including the West Indies, Central America, and South America down to Bolivia, per Kew POWO. The plant is a hemiepiphyte — it climbs trees in the wild using aerial roots, grows in the wet tropical biome.

This is the vining philodendron — distinct from the upright self-heading philodendrons (like 'Pink Princess' or 'Birkin') that don't trail. For care of the broader philodendron genus including the climbing and self-heading types, see our philodendron care guide.

Light

Bright indirect light. MBG describes the requirement directly: "Place in bright indirect light. Avoid full sun. Tolerant of shade, but if conditions are too dark, stems become spindly."

NC State lists the tolerance range as deep shade to partial shade. In practice, an east-facing window or a few feet back from a south window works well. Direct hot afternoon sun scorches the leaves.

If the plant looks leggy with long bare stems and small leaves, the light is too low. Move it closer to a window.

Watering

Keep the soil slightly moist; reduce watering in winter. NC State describes it as "slightly moist" — not soggy, not bone dry. MBG recommends regular watering during the growing season with reduced watering from fall to late winter.

Root rot is the main watering failure mode — same as every other tropical aroid. Make sure the pot drains.

Humidity

Medium humidity. NC State calls for "medium relative humidity" — meaning the plant tolerates average indoor air well. You don't need a humidifier or pebble tray for this one, unlike calatheas or Boston ferns.

Soil

Soil-based potting mix with good drainage per MBG. Standard houseplant mix with extra perlite works fine. The pH preference isn't documented in primary extension sources for this species.

Temperature

Average indoor temperatures per NC State. MBG lists USDA Hardiness Zones 11–12 outdoors, meaning the plant won't tolerate frost. Bring it inside before the first cold snap if you've been growing it outdoors in summer.

Pet safety

Toxic to cats and dogs per the ASPCA's Heartleaf Philodendron entry. Toxic principle is insoluble calcium oxalates. Symptoms include oral pain and swelling, drooling, vomiting, and difficulty swallowing. NC State also notes contact dermatitis from the sap.

Common problems

Symptom	Likely cause	Fix
Leggy stems, small leaves, long gaps between leaves	Light too low per MBG	Move to brighter indirect light; pinch back trailing stems to encourage bushier growth
Yellow lower leaves, mushy stems	Overwatering, root rot	Unpot, trim rot, repot in fresh airy mix; let dry between waterings
Brown crispy edges	Underwatering or low humidity	Water more consistently; consider pebble tray if your home is very dry
Aphids, mealybugs, spider mites, scale	All possible per MBG	Wipe leaves, treat with insecticidal soap or neem, repeat weekly for 3–4 cycles
Fungal leaf spots	Wet foliage from overhead watering per NC State	Water at soil level, not from above; trim affected leaves

Propagation

Stem cuttings root easily in water. Take a 4–6 inch cutting just below a node, remove the lowest leaf, and drop the node in water. Roots appear in 1–2 weeks. Pot when roots are 2 inches long.

You can also lay a long vine across moist potting mix in a separate small pot and pin one of the nodes down — it'll root in place, after which you can cut the connection to the parent plant.

Heartleaf philodendron vs. pothos

These two get confused constantly. Both are vining aroids with heart-shaped leaves. The reliable differences, per Illinois Extension:

Petiole groove: Pothos has a distinct channel running along the petiole; heartleaf philodendron has a smooth rounded petiole. This is the easiest single test.
New leaf emergence: Heartleaf philodendron's new leaves emerge wrapped in a thin papery sheath called a cataphyll, which turns brown and falls off as the leaf matures. Pothos doesn't have cataphylls.
Aerial roots: Pothos has one thick root per node; heartleaf philodendron has multiple thin roots per node.
Leaf texture: Pothos leaves feel thicker and waxy with slight surface texture. Heartleaf philodendron leaves are thinner and smoother.

Frequently asked

Is heartleaf philodendron safe for cats and dogs?

No. The ASPCA classifies Philodendron hederaceum as toxic to cats and dogs. The toxic principle is insoluble calcium oxalates, which cause oral pain, drooling, vomiting, and difficulty swallowing. NC State also notes contact dermatitis from the sap. Keep out of reach of pets that chew.

How do I tell heartleaf philodendron from pothos?

Look at the petiole (the stem connecting leaf to vine). Pothos has a deep groove running along it; heartleaf philodendron is smooth and rounded. New growth also differs — heartleaf philodendron leaves emerge wrapped in a thin papery cataphyll that browns and falls off, while pothos leaves unfurl without one.

Why is my heartleaf philodendron leggy?

Light is too low. Missouri Botanical Garden notes that in dark conditions, stems become spindly with long gaps between leaves. Move to brighter indirect light. You can also pinch back the leggy stems just above a node — the plant branches from the cut and fills out.

How often should I water heartleaf philodendron?

Keep the soil slightly moist during the growing season per NC State. Typically every 5–7 days in summer, less in winter. Stick a finger an inch into the soil — if the top is starting to dry, water. Reduce frequency from fall through late winter.

Can heartleaf philodendron grow in low light?

It tolerates low light better than most tropicals — NC State lists tolerance from deep shade up to partial shade. But the plant gets leggy and slow in dim conditions. Bright indirect light gives you a full, bushy plant. Deep shade gives you a thin vine with small leaves and long stems.
