How To Grow This Exotic Tree-Jacaranda mimosifolia

Jacaranda mimosifolia, Tall, stately, and lavender; it dominates cities in the warm climate world. There is a university in Australia at which, they say that if you haven’t started your final exam prep by the time the Jacarands blooms. you might as well go home! The students call spring the Jacaranda term and panic period. Another university, in Pretoria, says that if a Jacaranda flower falls on your head you will pass your exams.

So you can either study or hang around under the trees during exam week!

Where Can We Grow The Jacaranda

Jacaranda likes to be warm. It lives in USDA hardiness zones 9b-11. (Your hardiness zone.) Plant it in a sunny area protected by strong winds. Then give the tree a big space it can be 50′ high or more and as much as 30′ wide. Use an area with rich and well-drained soil. It can accept a variety of soils but prefers sandy soils.

You can grow the Jacaranda as a standard or multi-trunk tree, and it is semi-evergreen. It is appreciated for the soft filtered shade it provides.

If My Garden Is Too Far North

The Jacaranda tree does lend itself to bonsai. The bonsai will come indoors for the winter and outdoors in summer. If you like a project here is some information. Bonsai Empire.

I do read that jacaranda are grown in large pots and brought indoors for the winter, Listed below is a source of a true dwarf jacaranda reaching 10-12 feet in height. I would say this is for someone who really likes a project!

Places To See The Jacaranda

A Jacararanda tree in bloom

We love this tree in South Florida, also warm parts of Texas and Southern California. We enjoy them in our springtime but this was my most memorable view.

On a visit to the Hawaiian island of Maui, we drove one day, in our rental car to the unforgettable Ulupalakka Ranch, on the slopes of Mt Halaiakkala, the islands famous volcano. Quite a treat. See below.

Maui Hawaii If You Are Thinking of Going

We enjoyed Maui immensely. to know why, here is my view of Maui, I see it as divided into 6 distinct segments. Each has its own personality and I hope it helps you find the places you will enjoy most. “How to Visit Maui.”

One day we drove miles and miles upward in exotic scenery to arrive on a quaint New England hillside. Cattle and horses grazed as we looked leftward toward green pastures and the kind of stone walls I grew up near. The difference was that the animals grazed under the shade of a giant purple tree!

How We Got The Jacaranda

That is how the Jacaranda tree affects people. We love it. It started in central and south America and we humans took it to any climate in which it could possibly survive. It is appreciated in warmer parts of Europe, Florida, southern California, and throughout Asia. These are all places in which it is not native.

Baron Von Ludwig brought it to Capetown in 1829. He was Carl Ferdinand Heinrich Von Ludwig, born in Germany. He was a pharmacist, businessman, and confirmed plant hunter. He founded South Africa’s first botanical garden and assisted many visiting botanists. From Capetown, the Jacaranda spread widely. It dominates cities. They all love it. Some have festivals heralding it. Fly over photos show streets and city blocks outlined in purple,

In one city it is both loved and hated! Pretoria has a water problem, It is not the tree’s fault of course. But the Jacaranda, coming from a warm and wet climate uses lots of water, so they have banned planting new ones. People complained so much that the city compromised, You can now replace lost ones-but no new Jacaranda’s are allowed. In some parts of Australia and South Africa, it is considered invasive.

How To Grow the Blue Jacaranda If You Can-How To Appreciate It On Vacation

I am enjoying writing about flowering trees. We have lived in various climates and they have always been an important part of life. I started with the Magnolia and the Crabapple. I love them both and they live in many climates. That hopefully makes the information useful in lots of places.

The Jacaranda information is useful only if you live in a warm climate. The problem is that if you are a real gardener this is something wonderful that you won’t see. It is too big for a greenhouse although botanical gardens grow it under glass. So, here is all the information if you can use it. Otherwise, you can use it on a vacation. I hope you get to see one. They are unforgettable.

Why We Grow The Jacaranda-Tall, Stately And Lavender

We love it for the glowing purple clouds that surround us. There is no product to eat. It’s all about looking at it. There is a mild sweet honey smell. The name actually indicates fragrance. We talk mostly about the striking flower but the feathery foliage is memorable also. In fact owners of property with Jacaranda often light the tree to appreciate the foliage at night.

The Jacaranda attracts bees and hummingbirds making it rare and valuable in our efforts to attract pollinators. Because it attracts pollinators to urban areas that is an unusual value.

The Name Jacaranda mimosifolia

The genus of this plant is the jacaranda, with about 49 individual species. It is in the family Bignoniaceae which includes the tabebuia tree. The one with all the glamor though is Jacaranda mimosifolia so in everyday horticulture if someone says “I want a Jacaranda” this is what they want! How did we get the word? Jacaranda is thought to mean fragrant in a long-lost language from the parts of South America where it originated from.

The mimosifolia part means it looks like a mimosa, a fluffy leafed plant in the pea family.

Where Can We Use It

Types and Varieties of Jacaranda Trees

  • Jacaranda mimosifolia ‘Alba’ also called White Christmas. This is a large tree with white blossoms and is available from specialty growers. Care for it as you would any jacaranda.
  • Jacaranda mimosifolia ‘Bonsai Blue’ is a dwarf variety and matures at 10-12′ in height and 6-8′ wide. It is relatively new.
  • Pink! Stereosmermum kunthianum- is a tropical tree from Africa, with pink trumpet-shaped flowers and is called the”African Jacaranda’. While in the same family it is not a jacaranda. It is a pretty ornamental tree and much smaller than the jacaranda.

The Jacaranda Tree is Large-Tall and Wide

This is a true specimen tree, it will be the capstone of its landscape. It has open spreading branches and finely textured leaves. It takes 2-3 years for a seedling to bloom. This does not sound like a tree to start from seed, life is short, the Jacaranda is slow.

The blue jacaranda can reach 65′ in height and be nearly as wide! The canopy is light and you can plant under it. The jacaranda mimosifolia is known for a vigorous root system. It is a magnificent blue/purple flowering tree-but give it plenty of space!

The tree is reasonably drought tolerant but should be watered in dry periods. Like many flowering trees, the work is in getting it established, they are low maintenance after that.


Mature trees can survive cold periods to 25 degrees. They will not flower in periods of extended strong wind.

There is a new dwarf version available for small spaces and in pots.

Planting A Jacaranda

Plant the tree in an open spot with full sun. Water deeply and repeat when dry.

When Is The Jacaranda In Bloom And A Purple Alternative-The Purple Trumpet Tree

Expect to see this beautiful tree in bloom in the late spring into the summer. If you love the purple blooms and want more, read this piece on the Purple Trumpet Tree. It blooms in the same climate in early spring and is a much smaller tree and is available to you if your garden is not large enough for the approximately 50 feet size of the Jacaranda.

Comparing The Blue Jacaranda Tree and the Purple Trumpet Tree

For the trumpet-shaped blooms and beautiful blue/purple color, how do these two trees compare? Here are the similarities, they both offer trumpet-shaped blooms in large-sized groups, the blue/purple color, and prefer warm climates. The purple trumpet tree is much smaller and blooms earlier in spring. The Jacaranda is very large and has a longer bloom period, two months, and much later in the season.

Can you fit both of them in?

A Dwarf Jacaranda Tree

The Monrovia Company advertises a true dwarf tree, maturing at 10-12′ in height. Here is more information on it.

How To Prune The Jacaranda

This is a fast-growing tree, that implies softwood. Prune the tree in late winter before the new growth begins. Remove any branches growing at less than a 40-degree angle, these will be weak. Leave enough room between branches for air circulation. Maintain one main trunk. Remove enough branches to prevent enough weight to split the trunk.

Pests and Diseases of Jacaranda

This tree, like many, can be infested with aphids and scale which can be treated with insecticidal soap. The Jacaranda can be negatively affected by too little water or too much fertilizer. Annual feeding is sufficient.

What To Do If Your Jacaranda Does Not Bloom

Here are the issues most likely to affect blooming

  • Age of the tree: Jacaranda first bloom between the ages of 2-14 years from planting. A wide range-the earliest blooms come from grafted trees.
  • Soil fertility. High fertility is not required but excess nitrogen can be a deterrent.
  • Sunlight and temperature, full sun (6 hours or more) and warmth are important.
  • Moisture, overwatering is most negative, the trees often bloom well in drought conditions.
  • Excessive wind, particularly with salt, are negative. Plant the tree in a position allowing some protection from heavy winds.

Jacaranda for Pollinators

The iconic feature of the Jacaranda is the bright, bell-shaped tubular, purple inflorescence with thousands of flowers. The tube actually has a flat landing pad for the convenience of the bees. They land on it, drink the nectar and carry the pollen forward.

The tubular flowers attract hummingbirds also. I work on pollinator gardens, but often I think we underestimate the value of trees for pollinators.

Summary-How We Use Them

Los Angeles counted almost 150,000 Jacarandas in 2010. No one is sure where they came from but everyone appreciates them. The best guess is that during the gold rush ships bringing supplies to California would stop in Buenos Aires and someone thought they would be a good idea. Interestingly the jacaranda of South Africa also arrived during their gold rush and came from South America also in the 1880s!

The colorful trees are popular signs of spring in Florida, Texas, and California. I read some advice on pruning and it indicates how people become attached to the trees. It says they require regular pruning. Then it says “continue this practice for 15 years”. That’s dedication!
