How to identify it
Growth habit. Climbing / hemiepiphytic aroid. Starts life as a compact rosette of arrow-shaped juvenile leaves on short internodes; once it finds a support (a moss pole, a tree trunk in nature, or even a neighbouring pot), it climbs vigorously and the leaves transform into larger, pedately lobed adult leaves divided into 3–9 leaflets. Kept as a trailer or pinched regularly, the plant stays in its juvenile form indefinitely.
Leaves. Juvenile leaves are simple, arrow-shaped (sagittate) with a narrow basal sinus, 10–20 cm long, on long petioles. Adult climbing leaves become pedately lobed with 3, 5, 7, or up to 9 leaflets — almost unrecognisable as the same species. Leaves are mid-green in the wild species; cultivars range from silver-white through salmon pink to burgundy with various variegation patterns.
Flowers. Typical aroid inflorescence with a greenish-white spathe 8–12 cm long enclosing a cream-coloured spadix. Produced only by large climbing mature plants — rare in indoor cultivation and more often than not unnoticed.
Fruit. Clustered red-to-orange berries 1–2 cm across in the aged inflorescence. Essentially never seen in indoor cultivation.
- Arrow-shaped juvenile leaves with a distinct basal sinus and long petioles.
- Dramatic leaf shape transformation when allowed to climb — juvenile arrows become pedately lobed 3–9-leaflet adult leaves.
- Aerial roots at each node (aroid character), used for climbing.
- Cultivars in a wide range of colours including silver-white, pink, burgundy, and lime.
Commonly confused with
Arrow-leaf elephant ear
Much larger (1–2 m leaves) and typically grown outdoors from tubers. No climbing habit; leaves stay arrow-shaped throughout life rather than transforming.
Caladium
Also arrow-shaped, but leaves emerge from underground tubers and the plant dies back completely in winter. Caladium leaves are thinner, more papery, and often very brightly variegated.
Kris plant / Alocasia
Arrow-shaped but stiffer, much darker (nearly black-green), with prominent silvery veins. Forms a clump from a tuber rather than vining.
Heartleaf philodendron 'Brasil'
Heart-shaped rather than arrow-shaped leaves, without the distinct basal sinus of Syngonium. Smaller leaves overall.
Care
Light
Bright indirect light.
Place within 1–2 m of a bright window with filtered light. Direct sun bleaches and crisps the leaves, especially on pink and variegated cultivars. Deep shade causes variegated forms to revert to solid green and slows growth dramatically. The coloured cultivars — 'Pink Allusion', 'Strawberry Ice', 'Neon Robusta' — need the brightest indirect position in the room to hold their hues.
Seasonal: In Nordic winters, pink cultivars benefit from supplementary LED lighting; solid-green and white-variegated forms cope with the lower light.
Water
When top 2–3 cm of soil is dry.
Water thoroughly until runoff, then empty the saucer. Syngonium is thirstier than Monstera or Philodendron but far less drought-tolerant than aloe or jade — a common plant that is happy in a routine weekly watering. Drooping leaves usually mean thirst; yellow leaves usually mean overwatering.
Seasonal: Cut frequency by roughly a third from November to February.
Soil
Chunky aroid mix.
A blend of 2 parts peat-free potting soil, 1 part orchid bark, 1 part perlite, and a small handful of horticultural charcoal works well. The chunky mix provides the airflow aroid roots need while still retaining enough moisture between waterings.
Humidity
50–70 %; tolerates 40 %.
Moderate humidity supports larger, healthier leaves, but Syngonium is one of the more tolerant aroids in dry Nordic winter indoor air. Below 40 %, leaf edges can go crispy. A nearby humidifier helps.
Temperature
18–27 °C.
A warm tropical plant. Below 13 °C, leaves yellow and drop within days. Keep away from cold window glass in winter and from cold drafts.
Fertilizer
Balanced liquid feed monthly in spring and summer at half strength.
A balanced NPK (e.g. 20-20-20) at half the label rate supports the fast growth rate typical of young Syngonium. Over-fertilising burns leaf margins; pink cultivars are particularly sensitive to salt build-up. Flush the soil with plain water every 3 months.
Seasonal: Skip feeding from November to February.
Pruning
Pinch vines to keep the juvenile form and encourage bushiness.
Cut stems just above a node with clean sharp scissors whenever the plant starts to vine. Pinching back to the desired size produces a compact bushy rosette of juvenile leaves; left alone, Syngonium climbs aggressively and shifts to the larger, lobed adult leaf form that many growers find less attractive. Use the cuttings for propagation.
Repotting
Every 1–2 years; fast-growing when young.
Move up by one pot size (2–5 cm wider) when roots fill the pot. Best done in spring. Large specimens on moss poles may need stake support — once climbing, the plant grows vigorously and can outgrow a small pole within a single season.
Stem cutting in water
easy~2–4 weeksCut a section with at least one node and one leaf, ideally with an aerial root already present. Place in room-temperature water in bright indirect light; change water weekly. Pot up once new roots reach 3–5 cm. One of the easiest houseplants to propagate in water.
Stem cutting in soil
easy~3–5 weeksInsert the cut end directly into damp aroid mix. Cover loosely with a clear bag to hold humidity for the first 10–14 days; remove the bag daily for airflow. Rooting hormone is optional but speeds the process.
Division
easy~Immediate — divisions carry existing rootsMature clumps naturally divide into multiple crowns. At spring repotting, tease a crown away with its root system and pot separately. The parent plant usually regrows vigorously from the remaining portion.
Cultivars
'White Butterfly'
Pale silver-green central panels with darker green margins. The most widely available commercial cultivar; tolerates lower light than coloured forms.
'Pink Allusion' / 'Neon Robusta'
Pink-flushed leaves that intensify with bright indirect light. Pink fades in low light; 'Neon Robusta' is the deepest salmon-pink form.
'Maria Allusion'
Bronze to deep pink leaves with green edges. Compact habit, slower to vine than the species.
'Berry Allusion'
Soft pink and cream variegation on pale green leaves. One of the lightest-coloured cultivars; needs brighter light to maintain colour.
'Strawberry Ice' / 'Red Heart'
Deep pink-red veining on green leaves. Chimeric variegation; stable in tissue culture but reverts to green in deep shade.
Common problems
Pink / variegated cultivar reverting to green
Symptom
A formerly pink or silver-variegated plant produces new leaves that are mostly or fully green.
Cause
Insufficient light. Variegated and coloured cultivars need bright indirect light to maintain their variegation — in deep shade the plant reverts to chlorophyll-dominant green leaves for photosynthesis.
Fix
Move to a brighter indirect spot. Cut back fully green stems to a node where coloured leaves still emerge — the plant regrows with the original colouration in better light. If all stems have reverted fully, the original chimeric tissue may have been lost and the plant cannot recover its variegation.
Leggy, stretching stems
Symptom
Long stems with widely spaced leaves and few side shoots.
Cause
Insufficient light — Syngonium stretches toward whatever light it has.
Fix
Move to a brighter spot and pinch tips regularly (every 4–6 weeks) to encourage branching. Cut the leggy stems back to a node — the cut piece roots readily as a cutting, and the parent plant rebounds bushier.
Brown leaf edges
Symptom
Leaf edges and tips go brown and crispy.
Cause
Low humidity, salt build-up from over-fertilising, or tap water minerals.
Fix
Raise humidity above 50 %, flush the soil with plain water, and switch to filtered or rainwater. Pink cultivars are particularly sensitive to salt build-up — flush every 2 months rather than every 3.
Yellowing lower leaves
Symptom
Lower leaves yellow and drop; upper leaves fine.
Cause
Usually overwatering. Occasionally natural leaf ageing — Syngonium sheds old bottom leaves as new ones emerge on top.
Fix
Check soil — if it's wet or smells sour, unpot, trim dead roots, and repot in fresh chunky mix. If the soil is dry and only 1–2 leaves have yellowed, it's probably natural ageing.

Toxicity & safety
Intense immediate oral burning on chewing, drooling, swelling of lips and tongue, hoarseness, and difficulty swallowing. The severe pain typically prevents large ingestions. Sap on skin causes contact dermatitis in sensitive individuals.
Mechanism: Insoluble calcium oxalate raphides — microscopic needle-shaped crystals released from specialised cells (idioblasts) when plant tissue is chewed or damaged.
Syngonium podophyllum — Missouri Botanical Garden Plant FinderOral irritation, intense burning of lips, mouth, and tongue, excessive drooling, vomiting, and difficulty swallowing after chewing any part of the plant.
Mechanism: Insoluble calcium oxalate raphides.
Arrowhead Vine — ASPCA Toxic and Non-Toxic PlantsOral irritation, pawing at the mouth, drooling, vomiting, and difficulty swallowing after chewing any part of the plant.
Mechanism: Insoluble calcium oxalate raphides.
Arrowhead Vine — ASPCA Toxic and Non-Toxic PlantsA young Syngonium and a mature climbing Syngonium look so different that 19th-century botanists frequently described them as separate species. The juvenile-to-adult transition — from arrow-shaped simple leaves to pedately lobed 9-leaflet mature leaves — happens only after the plant finds a support and climbs. Left as a pot-trailing juvenile, Syngonium can stay arrow-leaved for its entire cultivated life. The same phenomenon occurs in other climbing aroids like Monstera (fenestrations appear only on climbing leaves) and is called 'heteroblasty'.
Frequently asked · 5
Are arrowhead plants toxic to cats and dogs?+
Yes — ASPCA lists arrowhead vine (Syngonium) as toxic to cats and dogs. All parts contain insoluble calcium oxalate raphides — microscopic needle-shaped crystals that cause intense oral burning, drooling, vomiting, and difficulty swallowing when chewed. The severe pain usually prevents large ingestions. If a pet chews a leaf, rinse the mouth with water and contact a vet if symptoms persist beyond an hour.
Why is my pink arrowhead plant turning green?+
Insufficient light. Pink Syngonium cultivars ('Pink Allusion', 'Strawberry Ice', 'Neon Robusta') need bright indirect light to hold their colour — in deep shade the plant reverts to chlorophyll-dominant green leaves for photosynthesis. Move to a brighter position and cut back fully green stems to a node where coloured leaves still emerge. If all stems have reverted, the chimeric tissue may be lost and the plant cannot recover its pink.
How do I keep my Syngonium compact and bushy?+
Pinch vine tips regularly — every 4–6 weeks — just above a node. Pinching forces the plant to branch and keeps it in its juvenile arrow-leaf form; left unpruned, Syngonium climbs aggressively and shifts to the larger, pedately lobed adult leaf form. Use the cuttings to propagate and fill the pot for an even bushier look.
How often should I water an arrowhead plant?+
When the top 2–3 cm of soil is dry — typically every 5–7 days in summer and every 10–14 days in winter. Syngonium is thirstier than most common aroids and drooping leaves are a clear thirst signal. Yellow leaves usually mean the opposite — overwatering — so confirm the soil is actually dry before reaching for the watering can.
Why do my Syngonium leaves look completely different on older plants?+
The species has heteroblastic leaves — juvenile and mature leaves are dramatically different shapes. Young plants and pot-trailing specimens keep simple arrow-shaped leaves; once the plant climbs a support, new leaves transform into pedately lobed adult leaves with 3, 5, 7, or up to 9 leaflets. Keep the plant pinched and unclimbed to maintain the juvenile arrow shape most people recognise.
