Frangipanis are deciduous to semi-deciduous tropical trees with fragrant summer flowers, and they grow well in Sydney in a sunny, frost-free spot with free-draining soil. The most common mistake is overwatering or planting them in heavy clay, which rots the soft stems.
This guide covers the types of frangipanis, planting, striking cuttings, pruning, fertiliser, the sap and root questions, and what a Sydney professional charges.
Key points
- Mature size varies widely by variety (indicative — check the nursery label), so choose a compact type if space is tight.
- Frangipanis need full sun, free-draining soil and protection from frost, and they lose leaves in winter.
- Maintenance is low: light pruning after flowering, a spring feed used as the label directs, and gloves for the milky sap.
- The sap can irritate skin and the plant is commonly listed as toxic to pets, so contact your vet if an animal chews it.
Frangipanis at a glance

Types of frangipanis and look-alikes
| Type | Size (indicative) | Best use | Notes |
|---|---|---|---|
| White frangipani | Varies (indicative — check the label) | Feature tree, courtyard | Classic white flowers with a yellow centre and a strong fragrance |
| Pink and red frangipanis | Varies (indicative — check the label) | Feature tree, pots | Colour varies by variety; most are the same species as the white form |
| Plumeria pudica | Varies (indicative — check the label) | Screen, large pot | Evergreen with spoon-shaped leaves, often called bridal bouquet |
| Wild frangipani tree | Varies (indicative — check the label) | Native garden | Usually the native Hymenosporum flavum, which is not a true frangipani |
| Japanese frangipani | Varies (indicative — check the label) | Check the label | A loose name used for several plants; confirm the botanical name before buying |
| Spelling variants | Not applicable | Not applicable | Franjapani and frangapenni are common misspellings of the same plant |
Where to plant frangipanis in Sydney
- Aspect: choose a sunny, north or west facing spot, because frangipanis in shade flower poorly and grow leggy.
- Shade tolerance: they will survive part shade, but expect fewer blooms and slower growth than in full sun.
- Spacing: leave room for the canopy to spread, and check the plant label (indicative — check the label).
- Clay soils in western Sydney: plant on a mound or in a raised bed so water drains away from the stem.
- Pots: use a free-draining potting mix and a pot with drainage holes, and bring cold-sensitive plants under cover in winter.
- Roots: choose a spot away from pipes and paving, though frangipani roots are generally not considered aggressively invasive.
How to plant frangipanis
- Plant in late spring or early summer, when the soil is warm and the risk of frost has passed.
- Choose a sunny site and improve drainage with coarse sand or compost, avoiding heavy clay pockets.
- Dig a hole about as deep as the pot and wider than the root ball, and check that water drains away.
- Remove the pot gently and plant at the same depth as the plant sat in the container.
- Backfill, firm lightly and water in well, then let the surface dry before watering again.
- Mulch loosely and keep mulch clear of the stem to prevent rot.
- Stake tall plants in windy spots, because the soft branches snap easily.
How to strike frangipani cuttings
Frangipanis strike readily from cuttings in warm weather, which is why neighbours often share them. A cutting should not go straight into wet ground.
- Take a healthy cutting from a mature branch in spring or early summer, using clean secateurs and gloves.
- Stand the cutting somewhere shaded and dry so the cut end can heal over for several days (indicative — check a nursery guide).
- Plant the dry cutting into a pot of free-draining mix, with only the bottom section buried.
- Water very lightly at first, then sparingly, because a wet cutting rots before it roots.
- Keep it in a warm, bright spot and avoid pulling on it to test for roots.
- Plant out or repot once new leaves appear and the plant has clearly rooted.
You can plant a cutting directly into free-draining ground in warm weather, but a pot gives you more control over moisture.
Caring for frangipanis
| Task | When | How |
|---|---|---|
| Watering | Spring to autumn | Water deeply but let the soil dry between waterings; follow Water Wise times of before 10 am or after 4 pm |
| Fertiliser for frangipani | Early spring and midsummer | Use a low-nitrogen, flowering fertiliser from Yates or Scotts exactly as the label directs |
| Mulching | Spring | Apply a thin layer and keep it clear of the trunk |
| Winter | Winter | Reduce watering once leaves fall and protect young plants from frost |
| Pruning | Late winter to early spring | Remove dead, crossing or weak wood; see the pruning section below |
| Pest and disease watch | Spring and summer | Look for rust and sap-sucking insects, and book a licensed pest controller for infestations |
Pruning frangipani trees: when and how
Pruning keeps frangipanis compact and encourages branching, but cuts bleed milky sap, so wear gloves and eye protection. Search terms like how to prune a frangipani tree all lead to the same basic method.
- When to prune frangipani in Sydney: late winter or early spring, once frost has passed and before new growth starts.
- When to prune frangipani in Perth: the same approach applies, but timing shifts with local conditions, so check a Perth nursery.
- Cut just above a branch junction or node using clean, sharp secateurs or a pruning saw.
- Remove dead, diseased or crossing branches first, then shorten overly long stems.
- Avoid cutting during humid, wet weather, because open cuts can rot.
- For tall trees, work above head height or near powerlines, book a qualified arborist. Pruning costs about $230 to $1375 per tree in Sydney, with $520 typical (October 2026).
Frangipanis: roots, sap and flowers
| Question | Short answer | What to do |
|---|---|---|
| Do frangipani have invasive roots? | Roots are generally shallow and not aggressively invasive | Keep a sensible gap from pipes and paving |
| Is frangipani sap poisonous? | The milky sap can irritate skin and eyes | Wear gloves and eye protection when pruning |
| Are frangipani flowers poisonous? | The plant is commonly listed as toxic if eaten | Do not eat any part, and keep children and pets away |
| Pets | Owners report vomiting and drooling after chewing | Contact your vet or the Animal Poisons Helpline |
Common problems with frangipanis
| Symptom | Likely cause | Fix |
|---|---|---|
| Not flowering | Too much shade, too much nitrogen, or a young plant | Move to full sun, switch to a flowering fertiliser used as the label directs, and be patient |
| Leaves drop in autumn | Normal winter dormancy | Reduce watering; leaves grow back in spring as soil warms |
| Soft, black stems | Rot from wet soil or frost | Cut back to healthy wood and improve drainage |
| Orange powder on leaves | Frangipani rust | Remove affected leaves, improve airflow and use a registered product exactly as the label directs |
| Yellow leaves in summer | Overwatering or a nutrient shortage | Let the soil dry between waterings and feed lightly |
| Leggy growth | Low light | Prune after flowering and move pots to a brighter spot |
FAQ: frangipanis questions
When do frangipani leaves grow back?
Frangipanis drop leaves in winter and shoot again in spring as the soil warms, usually around September to November in Sydney. A cold or wet winter can delay regrowth, so wait before assuming the tree has died.
Is frangipani sap poisonous?
The milky sap can irritate skin and eyes, and the plant is commonly listed as toxic to pets if chewed. Wear gloves and eye protection when pruning. If a pet or child is affected, contact your vet or the Animal Poisons Helpline.
Is frangipani native to Australia?
No. Frangipani comes from Central America and the Caribbean. The native Hymenosporum flavum is often called native frangipani but is a different plant. Check the botanical name on the label if you want a true Australian native.
Why is my frangipani not flowering?
The usual causes are too much shade, too much nitrogen or a plant that is still young. Move potted trees to full sun, use a flowering fertiliser as the label directs, and avoid overwatering in spring and summer.
