Arrowhead plant (Syngonium podophyllum) grows well in bright, indirect light, soil kept lightly moist and allowed to dry slightly between waterings, and warm temperatures with moderate to high humidity. Named for the arrow-shaped leaves it produces as a young plant, its leaf shape actually changes dramatically as it matures, especially if given something to climb. It’s a fast, easy-to-propagate houseplant, though its leaves and sap are toxic if chewed or ingested by people or pets.

About the Arrowhead Plant
Arrowhead plant, botanically Syngonium podophyllum, gets its common name from the distinctive arrow- or heart-shaped leaves it produces in its younger, juvenile growth stage. It’s a member of the aroid family, Araceae, making it a relative of philodendron, pothos, and monstera, and it’s native to tropical rainforests of Central and South America.
Arrowhead plant is available in a wide range of cultivars with different variegation patterns, from solid green varieties to those splashed with white, cream, pink, or burgundy, sold under names like ‘White Butterfly,’ ‘Pink Splash,’ ‘Neon Robusta,’ and ‘Albo Variegatum.’ Care is essentially the same across cultivars, though more heavily variegated types generally need brighter light to maintain their coloring than solid green varieties.
It’s also sometimes sold under the older botanical name Nephthytis, particularly in older gardening references or from growers who haven’t updated their labeling. Both names refer to the same plant, and you may still see “Nephthytis” used interchangeably with “Syngonium” or “arrowhead plant” at some nurseries.
Where to Display Arrowhead Plant
Because arrowhead plant’s look changes so much depending on whether it’s kept pruned into a bushy form or allowed to climb, it works well in a couple of very different display styles. As a compact tabletop or shelf plant, regular pinching keeps it neat and full, similar to how many aroids are displayed in offices and living rooms. Given a moss pole or trellis and left to climb, it becomes a much more dramatic vertical statement piece, gradually producing the larger, more divided mature leaves described above as it grows upward. Either style works well in a hanging basket too, where the trailing juvenile growth can spill attractively over the edge.
Juvenile vs. Mature Growth: Why Arrowhead Plant’s Leaves Change Shape
One of the most interesting and least-known facts about arrowhead plant is that its leaf shape genuinely changes as the plant ages, not just in size but in overall form.
Young plants produce the simple, arrow-shaped leaves the plant is named for, and stay relatively compact and bushy, which is how most arrowhead plants are sold and grown in homes. However, if the plant is given something to climb, such as a moss pole or trellis, and allowed to mature rather than being kept pruned back, its growth shifts into a vining habit, and new leaves emerge larger, more deeply lobed, and more divided, eventually looking quite different from the simple arrowhead shape of a young plant. This same general pattern, dramatically different juvenile and mature leaf forms within the same species, also shows up in its aroid relative monstera, which develops its famous split leaves only once it matures and is given support to climb.
Most home growers keep arrowhead plant pruned and pinched in its compact, bushy juvenile form, which is easier to manage on a shelf or tabletop. If you’re curious to see the more dramatic mature leaf form, though, providing a moss pole and allowing the plant to climb without heavy pruning is the way to unlock it. Keeping the moss pole lightly misted or damp encourages the plant’s aerial roots to attach to it more readily, helping the climbing stems support themselves as they grow taller and produce larger leaves.
Light Requirements
Arrowhead plant does best in bright, indirect light, which helps maintain vivid variegation on patterned varieties.
A spot near an east- or west-facing window works well. It also tolerates medium, and even fairly low, light reasonably well, particularly solid green varieties, though variegated types tend to lose some of their coloring and grow more slowly in dim conditions. Avoid direct, intense sun, which can scorch the leaves.
Watering
Water when the top inch of soil is dry, keeping the soil lightly, evenly moist rather than alternating between soaked and bone dry.
Arrowhead plant is more tolerant of slight underwatering than of consistently soggy soil, which can lead to root rot and yellowing leaves. During the growing season, this typically means watering roughly once a week, adjusting based on your home’s light and humidity levels. Always use a pot with drainage holes and let excess water drain away.
Soil and Potting
A standard well-draining potting mix works well, ideally with some added perlite to improve drainage further. Repot every year or two in spring as the plant grows, or sooner if you notice roots becoming crowded or growing out through the drainage holes. If you’d like to encourage the plant’s mature climbing growth form, this is also a good time to add a moss pole or trellis for it to grow up as it develops.
Temperature and Humidity
Arrowhead plant is comfortable in typical indoor temperatures, ideally 65-80°F (18-27°C), and should be kept away from cold drafts, exterior doors, and air conditioning vents.
It prefers moderate to high humidity, and while it tolerates average household conditions reasonably well, low humidity can contribute to dry, browning leaf edges over time. A humidifier, pebble tray, or grouping it with other humidity-loving plants can help, particularly during winter when indoor heating dries the air throughout the home.
Fertilizing
Feed with a balanced, water-soluble liquid houseplant fertilizer once a month during spring and summer while the plant is actively growing. Reduce or stop fertilizing in fall and winter, when growth naturally slows.
Pruning
Regularly pinching back the growing tips keeps arrowhead plant compact and bushy in its juvenile form, which is how most home growers prefer to display it. If left unpruned, particularly with a support to climb, the plant will naturally begin vining and producing the larger, more divided mature leaves described above. Either approach is a valid way to grow the plant; it simply depends on which look you prefer. There’s no need to worry about harming the plant by choosing one style over the other, since both juvenile and mature growth are perfectly healthy stages of its natural life cycle.
How to Propagate Arrowhead Plant
Arrowhead plant is one of the easier aroids to propagate from stem cuttings:
- Cut a stem section a few inches long, making sure it includes at least one leaf node.
- Place the cutting in a glass of water, or directly into moist potting soil.
- Keep it in bright, indirect light while it roots, changing the water every few days if rooting in water.
- Roots typically develop within 1-2 weeks; once established, transplant water-rooted cuttings into soil.
Multiple cuttings can be potted together in one container for a fuller-looking new plant right away.
Is Arrowhead Plant Toxic to Pets or Humans?
Arrowhead plant is toxic to cats, dogs, and humans if chewed or ingested.
Like many members of the aroid family, its leaves and sap contain calcium oxalate crystals, which cause immediate irritation, burning, and swelling in the mouth and throat if bitten into, along with drooling, vomiting, and difficulty swallowing in pets. This is a different toxicity mechanism than the saponins found in plants like Dracaena, but the practical advice is the same either way: keep the plant out of reach of pets and small children, and contact a veterinarian or poison control center if ingestion occurs.
Common Problems and How to Fix Them
Legginess or vining growth This is often just the plant’s natural mature growth habit taking over rather than a problem, though insufficient light can also contribute. Prune and pinch regularly if you want to maintain a compact, bushy form instead.
Brown, crispy leaf edges Usually linked to low humidity or inconsistent watering. Increasing humidity and watering more consistently typically helps.
Yellowing leaves Most often a sign of overwatering. Let the soil dry out more between waterings and check that the pot drains well.
Fading variegation Typically caused by insufficient light. Move the plant to a brighter spot with indirect light to help new leaves develop more vivid coloring.
Pests Spider mites, aphids, mealybugs, and scale can occasionally appear. Wipe down leaves periodically and treat promptly with insecticidal soap if pests are spotted, checking new growth and leaf undersides closely since that’s typically where infestations start.

Frequently Asked Questions
How do you care for an arrowhead plant?
Give it bright, indirect light, water when the top inch of soil is dry, use well-draining soil, and provide moderate to high humidity for the healthiest growth.
Why is my arrowhead plant vining instead of staying bushy?
This is often simply the plant’s natural mature growth habit, especially if it’s been given something to climb. Regular pruning and pinching keeps it in a more compact, bushy juvenile form instead.
Is arrowhead plant toxic to cats and dogs?
Yes, it’s toxic if chewed or ingested, due to calcium oxalate crystals in the leaves and sap that cause mouth and throat irritation, and it should be kept out of reach of pets.
How often should you water an arrowhead plant?
Water when the top inch of soil is dry, typically about once a week during the growing season, keeping the soil lightly and evenly moist.
Can arrowhead plant grow in low light?
It tolerates medium to fairly low light reasonably well, particularly solid green varieties, though variegated types grow more slowly and lose some color intensity in dim conditions.
Why does my arrowhead plant’s leaf shape look different from when I bought it?
Arrowhead plant leaves change shape as the plant matures, especially when given a support to climb, growing larger and more deeply lobed than the simple arrow-shaped leaves of a young plant.
Is arrowhead plant easy to propagate?
Yes, it’s one of the easier aroids to propagate, rooting readily from stem cuttings in either water or moist soil within one to two weeks.
Is arrowhead plant the same as Nephthytis?
Yes, Nephthytis is an older botanical name still used by some growers and nurseries for the same plant now classified as Syngonium podophyllum.
Should I let my arrowhead plant climb or keep it pruned bushy?
Either approach works well; it’s purely a matter of preference. Regular pinching keeps a compact, tabletop-friendly plant, while providing a moss pole and allowing it to climb unlocks its larger, more dramatic mature leaf form over time.
