Indoor Heart Shaped Plant: Best Varieties and How to Care for Them

There’s a reason heart-leaved plants are everywhere on windowsills and shelves, the romantic shape is charming, and most of these plants happen to be forgiving for beginners. An indoor heart shaped plant brings softness and life to a room without demanding much in return. But before you fill your home with them, there’s one honest caution worth getting out of the way: several of the most popular heart-shaped houseplants are toxic to pets and small children if chewed. We’ll cover the best varieties, how to keep them thriving, and exactly which ones to keep out of reach.

Heartleaf Philodendron

The heartleaf philodendron (Philodendron hederaceum) is the icon of the category, glossy, deep-green hearts on trailing vines that look great cascading from a shelf or climbing a small trellis. It’s wonderfully easy: it tolerates lower light, forgives the occasional missed watering, and grows quickly.

Give it bright, indirect light for the fullest growth, though it copes with medium light. Water when the top inch of soil dries out, and pinch back leggy vines to keep it bushy. It’s one of the most beginner-friendly houseplants you can buy.

Heart-Leaf Pothos and Other Pothos

Pothos (Epipremnum aureum) carries the same heart-shaped leaves, often splashed with golden, white, or marbled variegation. It’s nearly indestructible and a favorite for first-time plant owners. Pothos trails beautifully and roots easily in water, so one plant becomes many.

It thrives in bright, indirect light but survives in low light, with less variegation. Let the soil dry between waterings; pothos is far more forgiving of underwatering than overwatering, which causes root rot.

Hoya Kerrii (Sweetheart Plant)

If you want the heart shape at its most literal, the Hoya kerrii is a thick, succulent-like single heart leaf often sold as a Valentine’s gift. The full vining plant produces strings of these chubby hearts over time, though it’s a slow grower.

As a semi-succulent, it wants bright light and infrequent watering, let it dry out completely between drinks. Note that a single-leaf “heart in a pot” often won’t grow into a full plant unless a bit of stem was included, so manage expectations with those gift versions.

String of Hearts

String of hearts (Ceropegia woodii) is a delicate trailing plant with tiny silver-marbled heart leaves on thin vines that can grow several feet long. It’s stunning in a hanging pot where the strands can dangle.

Treat it like a succulent: bright light and sparse watering. Its slim vines and small leaves make it more of a statement piece than the fuller philodendron or pothos.

Important Safety Note: Toxic to Pets and Kids

This is the part too many plant guides skip, so let’s be direct. Many of the most popular heart-shaped houseplants contain insoluble calcium oxalate crystals, which cause mouth irritation, drooling, vomiting, and swelling if chewed or eaten.

• Toxic if ingested: heartleaf philodendron and pothos both contain calcium oxalate and are toxic to cats, dogs, and children if chewed.
• Generally considered non-toxic: Hoya kerrii and string of hearts are commonly listed as pet-safe, though any plant can cause mild stomach upset if eaten in quantity.

If you have curious pets or toddlers, keep philodendron and pothos well out of reach, on a high shelf or hanging planter, or choose the non-toxic options instead. If ingestion happens, contact your veterinarian, a poison control center, or your doctor. When in doubt about a specific plant, verify its toxicity with a reputable source before bringing it home.

General Care That Keeps Them Thriving

Most heart-shaped houseplants share the same basic needs, which is part of their appeal:

• Light: Bright, indirect light is the sweet spot. Direct sun can scorch leaves; deep shade causes leggy, sparse growth.
• Water: Let the top inch or two of soil dry before watering. Overwatering and soggy roots are the number-one killer.
• Soil and pots: Use a well-draining potting mix in a pot with drainage holes.
• Humidity and temperature: Average household conditions work; most prefer temperatures between 65 and 80°F and appreciate a little extra humidity.
• Feeding: A diluted balanced fertilizer during the growing season keeps them lush.

Styling Heart-Shaped Plants at Home

These plants are as decorative as they are easy. Let a pothos or philodendron trail from a high shelf, train one up a moss pole for vertical interest, or group several in a bright corner for a layered, green look. Hanging planters keep trailing varieties out of reach of pets while showing off their cascade, solving the safety problem and the styling problem at once.

Common Problems and How to Fix Them

Even easy plants run into trouble, and the symptoms usually point to a clear cause:

• Yellow leaves: Most often overwatering. Let the soil dry more between waterings and make sure the pot drains.
• Brown, crispy edges: Usually low humidity or underwatering; raise humidity or water a touch more consistently.
• Leggy, sparse vines: Not enough light. Move the plant to a brighter, indirect spot and pinch back to encourage fullness.
• Faded variegation: Variegated pothos lose their pattern in low light; give them brighter conditions.
• Pests (gnats, spider mites): Often tied to overwatering; let soil dry, wipe leaves, and treat as needed.

The single most common mistake across all of these plants is overwatering, so when in doubt, wait a day or two before reaching for the watering can.

Propagating for Free Plants

One of the joys of heart-shaped trailing plants is how easily they multiply. Heartleaf philodendron and pothos root from stem cuttings in water within a couple of weeks: snip below a node, set the cutting in a glass of water in bright indirect light, and pot it up once roots are an inch or two long.

String of hearts and hoya can also be propagated from cuttings, though they root a bit more slowly. Propagating lets you fill more of your home, share with friends, and replace any vines that get leggy, all without buying new plants. Just remember the toxicity note still applies to the propagated cuttings of philodendron and pothos.

The Bottom Line

An indoor heart shaped plant is one of the easiest ways to add warmth and greenery to a home, with the heartleaf philodendron and pothos leading for sheer toughness, and Hoya kerrii and string of hearts offering pet-safer charm. Match the plant to your light, water sparingly rather than generously, and, above all, keep the toxic varieties away from pets and small children. With a little awareness and very little effort, these heart-leaved beauties will reward you for years.
