Last updated
Arrowhead plant (Syngonium podophyllum) wants bright indirect light; the pink forms need more. Water it weekly. 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. Pot it in loose, airy aroid mix with plenty of bark and perlite. Balanced liquid feed at half strength every third watering through the growing season, and repot once a year. Humidity: fine at room humidity, faster growth above 60%. Toxic to cats, dogs and people if chewed — the sap carries insoluble calcium oxalate crystals, which burn the mouth and throat.
Arrowhead vine: it starts as a compact rosette of arrow-shaped leaves and then, given something to climb, turns into a vine with completely different lobed adult foliage. It grows fast, roots from anything, and comes in more colour forms than almost any other houseplant — pink, cream, speckled, near-white.

Watering an Arrowhead plant
Water weekly. 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. Plain green syngoniums manage in medium light; the pink, white and speckled cultivars lose their markings without a bright spot.
Humidity and temperature
Fine at room humidity, faster growth above 60%. 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 while young — they grow fast. A syngonium that is allowed to climb changes leaf shape entirely, from the arrowhead most people know to a large lobed adult leaf.
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
Node cuttings root in water within two or three weeks.
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 Arrow-Head Vine (Syngonium podophyllum) as toxic to cats and dogs (checked 26 October 2026).
If your pet has eaten a plant, call your vet, the ASPCA Animal Poison Control Center on (888) 426-4435, or the Pet Poison Helpline on (855) 764-7661. Both are open around the clock and may charge a consultation fee. Take the plant or its label with you.
This is general information, not veterinary advice. We don't test plants: what we say about toxicity follows the ASPCA's published plant list as it stood on 26 October 2026, and that list can change. "Non-toxic" means not poisonous — a pet that eats enough of any plant can still vomit, and fertiliser, pesticide or leaf shine on a plant can harm it. It also only helps if the plant is what you think it is. It covers cats and dogs only; ask your vet about rabbits, birds, reptiles or anything else, and a doctor about children. Read our terms.

Named cultivars and variegations
Syngonium podophyllum is sold under several cultivar names. Care is the same unless noted; variegated forms carry less chlorophyll, so they grow more slowly and want more light than the plain species.
| Cultivar | Also sold as | Water |
|---|---|---|
| 'Albo Variegatum' | Syngonium Albo | weekly |
| 'Pink Splash' | Pink Splash | weekly |
| 'White Butterfly' | White Butterfly | weekly |
| 'Pink Allusion' | Pink Allusion | weekly |
| 'Mojito' | Syngonium Mojito | weekly |
| 'Neon Robusta' | Neon Robusta | weekly |
| 'Three Kings' | Three Kings | weekly |
| 'Confetti' | Syngonium Confetti | weekly |
Where the variegated forms are grown differently from the plain Syngonium podophyllum:
'Albo Variegatum'
White sectors and half-white leaves on the arrowhead vine. Unstable. Difficulty: needs attention.
Light: Bright indirect light, no direct midday sun. The plain plant manages medium light; this one doesn't.
Humidity: Above 50%, ideally 60%.
Watch for: A new leaf that is entirely white, or nearly. White tissue has no chlorophyll, so the leaf cannot feed itself; it will brown and die early, and it means the stem is drifting towards white. Leave the leaf on while it lasts. If the next leaves are mostly white too, cut the stem back to a node below a leaf with a good share of green.
Watch for: New leaves coming in plain green. The stem is reverting: green tissue grows faster than the variegation, and a stem that has made one plain leaf will usually go on making them. Give it more light, and cut the stem back to a node below the last leaf with good variegation; growth from that node carries the pattern on.
'Pink Splash'
Green leaves speckled and splashed with pink.
Light: Bright indirect light keeps the pink. In a dim spot new leaves come greener.
Watch for: New leaves coming in plain green. The stem is reverting: green tissue grows faster than the pink, and a stem that has made one plain leaf will usually go on making them. Give it more light, and cut the stem back to a node below the last leaf with good variegation; growth from that node carries the pattern on.
'Mojito'
Marbled white and green, no two leaves alike. Steadier than Albo, but it can still throw plain leaves.
Light: Bright indirect light. In a dim spot the marbling fades and the stems stretch.
Watch for: New leaves coming in plain green. The stem is reverting: green tissue grows faster than the variegation, and a stem that has made one plain leaf will usually go on making them. Give it more light, and cut the stem back to a node below the last leaf with good variegation; growth from that node carries the pattern on.
'Neon Robusta'
Leaves almost entirely pink, with a little green at the veins. Pretty, and slow, because there is so little green to feed it. Difficulty: needs attention.
Light: Bright indirect light close to a window; no harsh afternoon sun, which bleaches the pink. In medium light the leaves come greener and smaller.
Water: Water when the top third of the pot is dry, and check before you water: with so little green it drinks slowly.
Watch for: New leaves coming in plain green. The stem is reverting: green tissue grows faster than the pink, and a stem that has made one plain leaf will usually go on making them. Give it more light, and cut the stem back to a node below the last leaf with good variegation; growth from that node carries the pattern on.
'Three Kings'
Cream-white marbling, often heavy, over most of the leaf. Difficulty: needs attention.
Light: Bright indirect light, no direct midday sun. With this much cream it needs more light than the plain plant to grow at all.
Watch for: Brown, dry patches on the cream parts of the leaves. The cream tissue is the weakest part of the leaf and fails first: sun through glass, dry air, or a plant shedding what it can't support. Move it out of direct sun and raise the humidity. The damage doesn't recover; trim it off with clean scissors once it covers much of a leaf.
Watch for: New leaves coming in plain green. The stem is reverting: green tissue grows faster than the variegation, and a stem that has made one plain leaf will usually go on making them. Give it more light, and cut the stem back to a node below the last leaf with good variegation; growth from that node carries the pattern on.
'Confetti'
Pink speckles over green leaves, denser on young growth.
Light: Bright indirect light keeps the pink. In a dim spot new leaves come greener.

Questions people ask
How often should you water an Arrowhead plant?
Water weekly as a starting point — that is the cadence PlantParlour sets for Syngonium podophyllum. 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, pot size and the time of year all move that number, so treat it as a reminder to go and check rather than a rule.
How much light does an Arrowhead plant need?
Bright indirect light. Plain green syngoniums manage in medium light; the pink, white and speckled cultivars lose their markings without a bright spot.
Is Arrowhead plant toxic to cats and dogs?
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 Arrow-Head Vine (Syngonium podophyllum) as toxic to cats and dogs (checked 26 October 2026). If a pet has eaten part of a plant, call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 straight away.
How do you propagate an Arrowhead plant?
Node cuttings root in water within two or three weeks.
