Things You May Not Know About The Jacaranda Tree
The dreamy haze of purple-blue lined streets.
Fallen flowers that make a beautiful carpet of blue.
Who doesn’t leave the beautiful jacaranda tree?
With Spring upon us, we thought we’d compile some facts about our favourite jacaranda tree!
- Jacarandas are not native to Australia
Jacarandas, also known as, jacaranda mimosifolia have been steadily growing in Australia for over 150 years, but despite this, are not native to Australia. Originally from parts of Central and South America, jacaranda seeds were thought to be brought along with sea captains sailing from South America, with Sir James Martin possibly planting the first jacaranda tree.
- Jacarandas are not native to Australia
- They grow tall and wide
- If you’re thinking about growing jacaranda trees, you’re going to need lots of space for them to thrive and flourish. Expect adult trees to grow at least 10-15m high and wide in optimum conditions, making them possibly not the best choice for a small backyard or either as a fence-side planting – your neighbours won’t be impressed!
- Jacarandas have a vigorous root system
- You’ll have to be careful where you plant your jacaranda tree. While also considering space, be careful not to plant it near drains, pipes, water lines and paths, as they have a vigorous root system and can cause fungal problems if dug or mowed out. Another common mistake people make is planting their jacaranda near a swimming pool; the fallen leaves rapidly clog up the filter and you will curse yourself for creating so much maintenance!
- Baby jacarandas hate the cold
- For the first two years of growth, you’re going to need to carefully look after your jacaranda plants as they’re quite susceptible to the cold and frost sensitive. After this period, they should be fine to grow and adapt to the Australian climate.
- The average lifespan of a jacaranda tree is 50 years old
- They can obviously grow a lot longer with some lasting well up to 200 years old. They reach maturity in about 20 years and are capable of re-growth if damaged from fresh falling seeds.
- Pruning can be difficult
- Pruning can be difficult as jacarandas react by sending out clusters of strong, vertical shoots which can detract from their appearance. Once you’ve started pruning a jacaranda tree, you will have to persist in cutting off the vertical shoots, so it’s best to leave it once it matures (formative pruning of young jacarandas are typically carried out in nurseries).

Spring Blooms, Rich Fall Hues, and Fast Tree Growth
Why Jacaranda Trees?
Incredible, long-lasting purple blooms in spring give way to rich, yellow hues in the fall, making the Jacaranda Tree a season-to-season star that stands out. Fernlike foliage lends volume to its bold, dramatic silhouette for a landscape look unlike any other.
Deep color emerges from its clusters of spring blossoms, which are visually breathtaking. A sea of lavender decorates the tree before leaves grow and makes the tree striking. But in addition to its unmatched beauty, the Jacaranda is fast-growing and drought-tolerant, adapting well to tough conditions.
Large, silky flowers hang in heavy, full bunches, ushering summer in after spring with ease. When the trumpet-shaped blooms finally fall, they form a lilac carpet beneath the awe-inspiring Jacaranda for luxuriant curb appeal.
Strength in beauty defines the unparalleled Jacaranda Tree. The powerful trunk and thick branches that hoist all those lovely blooms and gilt leaves are strong and resilient. It’s a tough tree that grows to a sturdy 40 feet height and will thrive in a variety of soil types.

Planting & Care
1. Planting: The Jacaranda is a full sun (6 to 8 hours of sunlight per day) lover that prefers well-drained soil.
Plant your Jacaranda in a hole that is 2 to 3 times the width of the container (the root ball), and just as deep. Place your tree and begin backfilling the hole, tamping down as you go to prevent air pockets. Place a thick layer of mulch over the planting area to protect the roots from fluctuating temperatures as well as help the tree to conserve water. Finally, water the tree well to saturate the entire planting area.
2. Watering: Water the Jacaranda Tree once or twice weekly while it’s establishing. Once established, the trees will only need water during times of extreme drought.
3. Fertilizing: Jacaranda Trees need very little fertilizer, but if you want to speed up growth, you can use a well balanced, slow-release formula, such a 10-10-10, in early spring.
4. Pruning: Only remove dead or damaged limbs.

Troubleshooting Jacaranda Tree Problems: Caring For Ailing Jacaranda Trees
The jacaranda tree (Jacaranda mimosifolia, Jacaranda acutifolia) is an unusual and attractive small garden specimen. It has delicate, fernlike foliage and dense clusters of lavender trumpet-shaped flowers. The fragrant blossoms grow from the branch tips. Some 40 feet tall with soft, spreading leaves, the jacaranda is a tree you don’t forget easily. But even beautiful trees can have problems, and you will sometimes see ailing jacaranda trees. Read on for information about problems with jacaranda trees.
Jacaranda Tree Problems
Problems with jacaranda trees are generally minor, ranging from a few insect issues to cultural problems. However, the tree is also susceptible to a serious jacaranda tree disease, a lethal bacterial infection.
The jacaranda tree can get aphids and scale, just like many other garden plants. Another insect pest, the glassy-winged sharpshooter, can also infest its leaves. Get rid of these pests by spraying with insecticidal soap or neem oil.
Too little water or too much fertilizer can also cause ailing jacaranda trees. You need to water the trees thoroughly every other week during the growing season, providing a long, slow drink. And skip the fertilizer – the trees grow better without it.
Over pruning or planting in shade can prevent a jacaranda from blooming. Too cold of weather can also cause jacaranda tree problems. They are sensitive to cold and can be seriously damaged by a frost.
Jacaranda Tree Disease
The glassy-winged sharpshooters that can infect jacarandas carry the lethal Xylella fastidiosa bacteria. If a tree is infected, it develops oleander scorch disease, for which there is no cure. This is the most serious of the jacaranda tree problems you are likely to encounter.
Identify the disease by yellowing leaves with dark margins. The bacteria proceed from the outer tips of the leaves inward, passing through all the branches. They plug up the xylem tubes that transport water, causing the tree to die of thirst.
Jacaranda Tree Root Problems
Jacaranda tree root problems are sometimes caused by incorrect care or culture. For example, the jacaranda requires well-draining soil. When planted on soil with poor drainage, the tree can develop mushroom root rot.
Other problems with jacaranda trees can develop from root issues. In fact, various root and stem rot pathogens attack jacaranda wood causing jacaranda tree root problems.
Flamboyant might be an understatement in describing a jacaranda tree in full bloom. Explosions of brightly colored purple flowers cover the tree’s canopy making it eye-candy for all to behold.
Beautiful Tropical Flowering Trees
Native to Brazil, the flowering specimen (Jacaranda mimosifolia) is a fast-growing deciduous tree reaching a mature height and width of approximately 40 feet. Its delicate fernlike foliage can appear before or after the tree begins flowering in springtime. The bark is grayish-brown in color and the canopy is vase-shaped and open.
When in bloom, it offers a riot of color within the landscape. Clusters of tubular flowers fill the canopy starting in April throughout August and last for approximately two months. Many times the flowers fill the tree’s canopy before the foliage springs to life. The most common one sold, grown, and seen in landscapes (Jacaranda mimosifolia) produces bright purple flowers. However, the cultivar ‘Alba’ produces whitish flowers, but isn’t as striking or as popular, though the period of blooming is a bit longer than the purple variety.
After flowering, the tree produces 3-inch round seedpods. The pods take approximately a month or two to ripen and then fall from the tree creating another litter problem.
What to Look For When Purchasing a Tree
Gardeners looking to add one of these tropical trees to their landscape should easily locate one at online or local nurseries throughout areas where they are hardy. Since the tree grows so quickly, most trees for sale average around the 1-year-old category. When purchasing a tree, look for one that is healthy and without signs of disease or damage and has one main trunk. Trees with multiple trunks aren’t as strong and are more prone to splitting.
The tree’s container should be large enough to hold the tree without signs of the roots growing out of the bottom drain holes. When held in containers that are too small, the roots have a tendency to wrap in circles and when planted, the tree may never grow properly. Average size containers range in the 3 to 5 gallon size for healthy growth.
Due to their soft wood and the messy litter they create when dropping their foliage and flowers, plant a jacaranda away from structures or pools. They make attractive specimen trees and their dropped flowers leave a carpet of purple beneath the tree. They also work well used along a sidewalk, as shade trees, or planted among evergreen trees as they continue to add color to the area when they drop their leaves in late autumn and winter.
Preferred Growing Conditions
Jacaranda isn’t a fussy tree when it comes to its preferred conditions for growth. Gardeners living in USDA zones 9 through 11 should have few problems growing this carefree tree.
For the best growth and flowering, plant it in a location that receives full sun. It will grow in locations with lower levels of light, but at the expense of the potential amount of flowers.
The tropical flowering trees grow well in various soils that drain well and do not perform well in soils that are prone to sogginess. There is no need to amend the soil with organic matter because the tree produces vigorous growth even in the poorest soils.
Preferred Temperatures and Frost Protection
Since jacarandas grow best in subtropical and tropical climates, they do not tolerate long periods of frost or freezing conditions. Temperatures of 27 degrees Fahrenheit can damage or kill trees, especially if the cold temperatures are prolonged, and the tree is young.
Due to the tree’s quick growth and size, it’s hard to offer winter protection for mature trees. When dealing with smaller trees, gardeners can hang holiday lights throughout the canopy to create a warm environment. Regardless of size, saturating the planting site with water to moisten the tree’s root system in the event of an unexpected frost or freeze helps it retain warmth.
In Western desert areas of the United States where temperatures are high, plant the specimen on the eastern, southern, or northern side of the house to prevent the trunk from getting sunscald. In these locations, the sun’s rays are intense and planting on the western side of the house opens the trunk up to burning.
Propagation and Planting
Gardeners can propagate jacaranda trees through softwood cuttings or through planting seeds. However, note that seed-grown trees take a long time to produce flowers and it can take as long as 20 years before flowering occurs. Trees propagated through softwood cuttings can bloom in in a couple of years after planting, depending on the size of the cutting at the time of propagation.
Propagating the tree through planting seeds is basic.
- Select fully ripe seed pods from the tree, which turn completely brown and easily open, revealing the round seeds contained inside the pod.
- To prevent having to transplant the seedling quickly into a larger container and allow it enough space to grow into a small sapling, use a 1 gallon container with bottom drain holes.
- Fill the container with a potting mix that drains well.
- Plant the seed about 1 inch deep into the center of the container and cover with soil.
- Water the container after planting and keep the soil moist through continued water applications.
- The seed should sprout in approximately four weeks.
Planting Softwood Cuttings
To achieve a blooming tree quicker, propagate using softwood cuttings taken while the tree is in its dormant state.
- Trim a branch from the mother tree that is anywhere from 2 to 4 feet long. Slant the cut on the end of the branch that you will plant in the soil.
- To keep from having to transplant into a larger container too quickly, thus allowing the roots to develop without being disturbed, use a 3-gallon container to grow the sapling.
- Fill the container with a well-drained potting mix and water to help the soil settle inside the container. Use a stick and make a hole in the container that is about 4 inches deep.
- Place the slanted end of the softwood cutting inside the hole and firm the soil around the cutting. Add more soil to the container if needed and firm around the cutting again.
- Water the container after planting and keep the soil moist through regular water applications. The root system should establish itself in approximately eight to 12 weeks.
Planting Developed Trees
Once you’ve selected an appropriate site in the landscape with preferred light and soil conditions, it’s time to plant the tree. Plant it directly in the native soil without adding any amendments.
- Remove all grass and weeds from a planting site that is approximately 3 feet in diameter. The unwanted growth robs the tree’s roots of moisture and opens the tree up to damage from lawn equipment, which can damage the trunk opening it up to disease problems.
- Dig a hole that is two to three times deeper and wider than the root ball. This loosens the area so the roots have an easier time spreading throughout the planting site.
- Backfill soil into the hole so you plant the tree no deeper than it was growing inside its container. Planting the jacaranda too deep puts undue stress upon the tree.
- Fill the hole halfway with soil and tamp it down with your foot and water the area to release unwanted air pockets. Finish filling the hole with soil and firm it up around the tree.
- Apply a 3-inch layer of mulch spread evenly over the planting site to help the soil conserve moisture. Keep the mulch several inches away from the trunk so you do not open the area up to disease.
- Water the planting site immediately after planting thoroughly saturating the roots. Water daily for the first few weeks while the root system establishes itself, which can take several months. Thereafter, water several times weekly, especially if conditions are hot and dry.
The trees are hardy and provided the preferred growing conditions do not need much attention besides proper pruning to survive and grow into healthy specimens. With their ability to grow in even the poorest soils that lack nutrients, fertilizing isn’t necessary to produce abundant growth.
Jacaranda has a high tolerance to drought conditions once established though regular water applications produce the best growth and production of blooms. However, during the establishment of roots in the planting site, newly planted trees require applications of water several times weekly or daily if outdoor conditions are hot and dry. Once the tree establishes itself into the landscape which takes approximately two to three months, watering several times weekly is sufficient.
Pruning is the most important aspect of caring for the jacaranda tree, especially while it’s young and developing its form. Do your pruning tasks after the tree has finished blooming in late summer so you don’t lose blooms. If the tree has several main branches forming the trunk, select the hardiest branch and prune off the others at ground level. If additional branches form along the trunk area, keep them pruned off.
Prune off any branches that are crossing or broken and any branches competing for space while the tree is young to create a stronger structure. To elevate the base of the canopy so you can walk under the tree, trim off branches forming along the trunk to a preferred height. Remove approximately one-quarter of the canopy to remove unnecessary branches and any large branches growing at the canopy’s edge. Pruning while the branches are small prevents trimming off large branches, which opens the tree up to possible diseases.
Pest and Disease Problems
Pests are not a problem for jacaranda trees. Trees planted in conditions that are too wet can experience problems with disease. Mushroom rot is a problem when the roots grow in soggy conditions. Gardeners may first notice the problem by the foliage starting to lose its color and then a mushroom formation attaches itself to the base of the trunk. For established trees, there is no solution to the problem because the planting site is too wet and the tree can die. To avoid the problem of rot, always plant it in a site with well-drained soil.
Purple is the color of royalty and the jacaranda tree’s intensely colorful canopy of blooms is anything but common. You will be the envy of your neighbors when this tree busts into bloom and your landscape is sure to get the attention it deserves by this one majestic addition.
Family: Bignoniaceae Origin: South America
While Jacaranda is the name of a genus of 49 species of trees and shrubs, in Brisbane Jacaranda usually refers to Jacaranda mimosafolia. They have been grown in Brisbane since popularized by the original botanic gardens in the 1800’s. Goodna even has an annual Jacaranda festival, making it even harder for a certain ecologically-friendly arborist to convince people to have these weeds removed.
It is prolific, which is one of its main problems. That is, it has become naturalised in areas around Ipswich and so made it onto Weeds Australia’s undesirable list. Ipswich council is largely to blame, having used them as street trees. It’s another lesson to favour native Australia trees.
If your Jacaranda is struggling, make sure it has full sun and good drainage. They need both. Also look for root damage by neighbouring houses or public works. Their roots travel for quite some distance and damage they suffer will be reflected in the visible part of the tree.
On the other hand, it could be something else. Brisbane residents might remember the media attention given to the death of a number of Jacarandas in New Farm park. While the consultant arborist (‘Ecca’) put it down to their age, I suggest they probably fell prey to a soil borne organism. Bear in mind the short time between their deaths as well as their proximity to the Brisbane River. I’m thinking they may susceptible to a fungus. Again, they need good drainage.
Considering their ‘undesirable’ status, removal is certainly an option for currently-grown Jacarandas in Brisbane. Pruning should be done by an arborist as incorrect pruning causes deadwood in these species which may pose a danger later.
They also tend to split down inclusions of bark, so removing weight from heavy scaffold branches improves their safety. At the same time, branches must be pruned back to leaders to avoid watersprouts forming. Don Burke recommends against pruning them at all to avoid watersprouts however an arborist can prune Jacarandas while avoiding their formation completely.
Below is a photo of a Jacaranda that uprooted in Highgate Hill after heavy rain.
The foliage of Jacarandas is very similar to Poincianas so they can be difficult to tell apart, except for their bark. Jacarandas have a vertically ridged bark with a soft feel, while Poincianas have smooth bark.
Tree to around 12 metres in height and 10 metre diametre canopy. Strongly decurrent, they have a quite rounded canopy. Jacarandas are low forking and occasionally exhibit multitrunk clumping.
Jacarandas put on an impressive flowering display starting around November each year. There is a saying at the University of Queensland (where streets are lined with Jacarandas) that one should start studying when Jacarandas start to bloom, but when the Poincianas start flowering it’s too late.
Jacarandas have tubular flowers to 50mm long in panicles growing upto 300mm in terminal clusters. Flowering is profuse and can cover the whole tree. After the flowers expire they tend to blanket the ground below.
Grain is quite straight and the wood cuts easily being soft yet not pithy. It is used in wood turning though is considered to soft for furniture or structural purposes. As part of our reuse of timber project, we often have Jacaranda timber available for wood turners: please comment below to enquire.
Jacarandas are invading bushland outside of Ipswich. They have become naturalized and are considered a threat to native species. In turn, this affects wildlife that depend on native flora for food. Jacarandas should not be propogated and consideration given to removing trees near bushland.
Jacaranda flowers attract insects, especially bees. This can, according to a vet, lead to dogs and cats being stung. She sees an increase in bee stings in animals from Jacaranda flowers, so raking the flowers is recommended from November to late March.
Gardening Fact Sheet: The Jacaranda

- Jacaranda flowers
- Jacaranda Mimosifolia
- Fallen jacaranda flowers
Australian streets are awash with the magnificent purple-blue blooms of jacarandas (Jacaranda mimosifolia) in late spring and early summer.
As well as being superb street trees, jacarandas look stunning on their own as a specimen tree in an open lawn, where their fallen flowers form a colourful carpet of blue.
Lots of people think jacarandas are natives, but they’re not. They are native to Brazil, where they are deciduous, not because of cold winters, but because of the monsoonal wet and dry seasons. They briefly drop their leaves at the end of the dry season, then leaf up again when the rains come.
These trees can reach a height of around 10-15m, and a spread of the same size, so you need to be careful where you plant them, as they can extend a long way. One big mistake some people make is to let a jacaranda overhang their swimming pool, where the fallen flowers rapidly clog up the pool’s filter. However, planted in the right spot, a jacaranda is a magnificent shade tree.
While the most common flower colour for jacarandas is the lovely purple-blue, there is a white-flowered form called ‘White Christmas’, but it is much harder to find this one at nurseries, and you’ll probably need to get it ordered in for you. For the most reliable blue colour, and faster flowering, look for a modern grafted form. Jacarandas are readily available at nurseries in tropical and warm temperate zones.
Jacaranda Growing tips
Jacarandas thrive in tropical and warm temperate climates, but they can be grown in cooler areas which get light frosts, but they usually don’t flower as well in these cooler zones, and they are also slower-growing, and smaller there.
Jacarandas like a sunny position and well-drained, fertile soil, plus regular summer watering. Mulching around the roots with organic material (eg, compost, straw, bark, etc) will help to retain soil moisture in summer, but only apply the mulch over moist ground, not over dry ground, otherwise the mulch might prevent rain reaching the soil. A thickness of no more than 50mm of mulch is recommended.
While jacarandas can be grown from seed, their flower colour varies more and they take longer to flower, but as seedlings often pop up around the base of trees, transplanting them is worth a try and doesn’t cost a cent.
Don’t prune them!
Forget about pruning jacarandas altogether or you will spoil their good looks, and the tree’s shape, forever. When you prune a jacaranda it then sends up vertical shoots (you’ll often see the effect on jacaranda street trees which have been pruned to make room for overhead powerlines). The normal shape for a jacaranda is that of an elegant umbrella, and the appearance of vertical branches ruins its good looks. Your only solution, if you have pruned a jacaranda, is to persist in cutting off the vertical shoots.
