Botanical Description
Frangipani trees possess distinctive features that make them a beloved tropical plant. You’ll find their structure, flowers, and leaves to be truly captivating.
Plant Structure
Frangipani trees have a unique growth habit that sets them apart. You’ll notice their thick, fleshy branches that grow in an open, spreading pattern. These branches are often bare for much of the year, giving the tree a sculptural appearance.
The bark is smooth and greyish-green, with prominent leaf scars. As the tree matures, it can reach heights of up to 8 metres, though some dwarf varieties stay much smaller.
Frangipanis are deciduous in cooler climates but may retain their leaves year-round in warmer areas. You’ll find they’re quite slow-growing, which makes them perfect for smaller gardens or large pots.
Flower Characteristics
The frangipani’s flowers are its crowning glory. You’ll be mesmerised by their beautiful, highly perfumed blooms that appear in clusters at the branch tips.
Each flower typically has five petals arranged in a pinwheel shape. The most common colours are white with a yellow centre, but you can find varieties in shades of pink, red, and even multicoloured forms.
The flowers are waxy and robust, lasting several days when picked. You’ll love their sweet, intoxicating fragrance that’s strongest in the evening.
Flowering usually occurs from late spring through autumn, with peak blooming in summer. After flowering, long, slender seed pods may develop, though this is less common in cultivated plants.
Leaf Features
Frangipani leaves are just as striking as their flowers. You’ll find them arranged spirally at the branch tips, often in rosette-like clusters.
The leaves are large, typically 15-30 cm long and 4-8 cm wide. They’re oblong or elliptical in shape with a glossy, leathery texture. The upper surface is dark green, while the underside is paler.
In most varieties, the leaves have a prominent midrib and parallel veins running to the leaf margins. Some cultivars offer variegated foliage for added interest.
When damaged, the leaves and stems exude a milky sap. Be careful, as this sap can cause skin irritation in some people.
Growth and Cultivation
Frangipanis are hardy trees that thrive with proper care. You’ll find them easy to grow when you provide the right conditions and follow a few key guidelines.
Soil Requirements
Frangipanis prefer well-draining soil to prevent root rot. Sandy or loamy soil works best, allowing excess water to move away from the roots quickly.
You can improve heavy clay soil by mixing in organic matter like compost or well-rotted manure. This enhances drainage and adds nutrients.
For potted frangipanis, use a quality potting mix designed for flowering trees. Add some coarse sand or perlite to boost drainage further.
Frangipanis don’t need overly rich soil. In fact, they often flower better in slightly nutrient-poor conditions. Avoid over-fertilising, as this can lead to lush foliage but fewer blooms.
Climate and Temperature Needs
Frangipanis thrive in warm, frost-free areas. They’re ideal for subtropical and tropical climates but can also grow well in temperate zones with some protection.
These trees love full sun and heat. You’ll get the best flowering results by planting them in a spot that receives at least 6 hours of direct sunlight daily.
While established frangipanis can tolerate brief periods of light frost, prolonged cold can damage or kill them. If you live in a cooler area, consider growing your frangipani in a pot. This way, you can move it to a sheltered spot during winter.
In very hot climates, provide some afternoon shade to prevent leaf scorch, especially for young trees.
Planting Recommendations
When planting your frangipani, choose a spot with good drainage and full sun. Dig a hole twice the width of the root ball but no deeper.
Place the tree at the same level it was growing in its pot. Backfill with soil, firming gently to remove air pockets.
Water thoroughly after planting, but allow the soil to dry out between waterings. Frangipanis are drought-tolerant once established and prefer to be on the dry side.
For potted frangipanis, choose a container with ample drainage holes. Use a pot slightly larger than the root ball to allow for growth.
You can propagate frangipanis easily from cuttings. Take 30cm cuttings in late spring or summer, allow the cut end to dry for a few days, then plant in a free-draining mix.
Care and Maintenance
Proper care and maintenance are essential for keeping your frangipani tree healthy and blooming beautifully. Focus on watering, fertilisation, and pruning to ensure your tree thrives.
Watering Guidelines
Frangipanis are drought-tolerant plants that prefer dry conditions. Water your tree sparingly, allowing the soil to dry out between waterings. During the growing season, water deeply once a week if there’s no rainfall.
In winter, reduce watering significantly as the tree enters dormancy. Overwatering can lead to root rot, so ensure your frangipani is planted in well-draining soil.
If you’re growing your frangipani in a pot, make sure it has drainage holes. Water thoroughly until it runs out the bottom, then allow the soil to dry before watering again.
Fertilisation Practices
Frangipanis benefit from regular fertilisation during their active growing period. Apply a balanced, slow-release fertiliser in spring when new growth appears. Choose a fertiliser with equal parts nitrogen, phosphorus, and potassium (NPK).
For potted frangipanis, use a liquid fertiliser every two weeks during the growing season. Reduce fertilisation in autumn and stop completely in winter when the tree is dormant.
Avoid over-fertilising, as this can lead to excessive leaf growth at the expense of flowers. If you notice yellowing leaves, it might indicate a nutrient deficiency. In this case, apply an iron chelate supplement.
Pruning Techniques
Pruning your frangipani helps maintain its shape and encourages more blooms. The best time to prune is in late winter or early spring before new growth starts.
Remove any dead, damaged, or crossing branches. To encourage a bushier growth, pinch out the growing tips of young branches. This will promote branching and result in more flowers.
For older trees, you can cut back branches by up to one-third of their length to control size and shape. Make clean cuts just above a leaf node at a 45-degree angle.
Remember to sterilise your pruning tools before and after use to prevent the spread of diseases. Allow cut ends to dry and callous over before watering to prevent fungal infections.
Pests and Diseases
Frangipani trees, while generally hardy, can face several threats from pests and diseases. Proper identification and timely action are crucial for maintaining the health and beauty of your frangipani.
Common Pests
Frangipani trees are susceptible to various pests that can damage their leaves and stems. Frangipani rust is a common fungal disease that forms yellow-orange pustules on the undersides of leaves. You’ll notice these pustules in late summer and early autumn.
Scale insects and mealybugs are other frequent visitors. They feed on plant sap, weakening your tree. Look out for small, waxy bumps on stems and leaves.
Spider mites can also be a nuisance, especially during dry conditions. These tiny pests cause yellowing and stippling of leaves.
To control these pests, try:
- Regularly inspecting your tree
- Using insecticidal soap or neem oil for mild infestations
- Pruning heavily infested branches
- Encouraging natural predators like ladybirds
Disease Prevention
Preventing diseases is easier than treating them. Frangipani rust can spread quickly, so it’s essential to act fast. Remove infected leaves and apply a fungicide containing copper oxychloride or sulphur with mancozeb.
To keep your frangipani healthy:
- Ensure good air circulation around the tree
- Water at the base, avoiding wet leaves
- Sterilise pruning tools between cuts
- Apply a balanced fertiliser in spring
If your frangipani produces few leaves or only flowers, it might not be receiving enough nutrients. Check the roots for rot and treat with an anti-rot solution if necessary.
Remember, a healthy tree is more resistant to pests and diseases. Regular care and attention will help your frangipani thrive and remain a stunning feature in your garden.

This variety is smaller than P. rubra, making it ideal for compact gardens or as a potted plant. You’ll find it easier to grow in cooler climates due to its evergreen nature.
P. obtusa is less common but equally stunning. Its flowers are typically larger and more fragrant than those of P. rubra. You might consider this variety if you’re after year-round greenery and a classic frangipani look.
Propagation Methods
Frangipanis can be easily multiplied through two main methods. Each approach has its own benefits and techniques to ensure successful growth of new plants.
Seed Sowing
Sowing frangipani seeds is an exciting way to create unique varieties. You’ll need to collect ripe seed pods from mature trees in autumn. Once the pods split open, gather the winged seeds.
Prepare a seedling tray with well-draining potting mix. Sow the seeds on the surface, pressing them lightly into the soil. Keep the tray warm and moist, but not waterlogged.
Germination typically occurs within 2-4 weeks. Once seedlings develop their first true leaves, transplant them into individual pots. Seedlings can grow quite large, reaching around 8 metres tall when mature.
Cuttings
Propagating frangipanis from cuttings is the most common and reliable method. Take 30-40cm cuttings from healthy branches during the dormant winter period. Remove leaves and allow the cut end to dry for a week to form a callus.
Plant the cuttings in a mix of sand and perlite, keeping them in a warm, sheltered spot. Water sparingly until roots develop, which can take 6-8 weeks.
Once rooted, transplant the cuttings into larger pots with well-draining soil. Cuttings will produce exact copies of the parent plant, ensuring you get the same flower colour and fragrance.
