How to grow Frangipani

Once you’ve been seduced by the sweet scent of frangipani you’ll fall in love with their grace, grandeur and simplicity. Linda Ross shares her passion for the world’s most beloved fragrant tree.


It may come as a surprise, but frangipanis come from Mexico, which is why they love the hot dry climates of Australia. During the 15th century the Aztec civilization immortalised the flowers in frescoes and stone carvings. 

 

When the Spanish opened up Mexico during the 16th century, the resulting trade routes ensured the spread of frangipanis to Asia. Buddhists adopted it as their Temple flower or Pagoda tree and it became synonymous with the tropics.

The icon of the tropics is an easy flower to grow. Frangipani love neglect, dry soils and full sun and are easy to strike from cuttings. Use the shape of the frangipani to your advantage in the garden, taking note of its wide umbrella shape. Plant it somewhere you can admire it from up close, or benefit from the shade it offers by planting one of the western side of your house.

Mature frangipanis can grow to around 6m high and 5m wide, but they grow slowly, only about 20cm per year. This slow growth, along with their small root ball, makes them ideal around pools, in planter beds, containers and beside walls, as there is no fear the roots will harm any structures. If they become top heavy they can be pruned without fear of failure. Trees around pools can be trained to tilt from a young age, giving the impression the tree is leaning over and hugging the pool.

For gardeners restricted to containers on terraces, roof gardens, balconies, decks and patios, low-care frangipanis are the perfect choice! They grow well in pots, flowering reliably every summer. Choose a quality potting mix and a wide shallow pot. Water only in spring and summer and allow to dry out during the cooler months.

 

What they need

Frangipanis thrive in well-drained soil, plenty of sun and frost-free conditions. They love growing by the beach in sandy soils and are one of the best trees for tolerating salty air along the coast. They will struggle in clay soils and in this case it is best to keep them growing in large containers. Frangipani rarely need feeding, although they will benefit from some fertiliser around the drip line (under the branches) during spring/summer.

In cooler areas it is still possible to grow a frangipani if the microclimate around the house is warm. Radiating sun and heat from brick paving, walls or mirrors will help the frangipani withstand cooler winters. In frosty areas it is still possible to grow frangipanis in containers as long as they are brought inside during the winter months.

 

Possible problems

During wet cool weather frangipanis can be at risk of root, branch and tip rot, which is caused by a fungus. To check on your plant’s health squeeze the stems: a firm stem indicates a healthy tree. To reduce the risks avoid watering in winter. If the stem becomes wrinkled the tree is not well. Cease watering and spray leaves with AntiRot. If you notice spongy stems, remove the stem completely to the junction with a main branch. Thinning out 15 – 20% of the canopy of your mature frangipani is good to do every few years; it opens up the branches, allows light in and reduces stem rot.

 

Plant notes: Our favourite frangipani


Frangipani enthusiast, Steven Prowse, of Sacred Garden Frangipanis at Mt. Garnet in far North Queensland, boasts a rainbow collection of frangipani cultivars. Some of his discoveries date back to trees brought to the tropical north by Polynesian Christian missionaries in the late 19th and early 20th centuries- now these trees grow wild. These have been combined with exciting varieties from Thailand to result in some stunning flowers.
