Jacaranda Season! Growing Jacaranda Trees in South Australia

Jacaranda Season! When the World Turns Purple đź’ś
Tell me, you can't deny that there's something magical about a tree that spends much of the year minding its own business, then suddenly decides to put on the most spectacular floral display you could ever hope to image in spring!
And that's exactly what the beautiful Jacaranda (Jacaranda mimosifolia)Â does!
Those gorgeous clouds of lavender-blue flowers, delicate fern-like foliage and the unmistakable purple carpets beneath them are enough to make you stop, look up and smile.
And when they're flowering en masse? Words can't describe!
Adelaide's Beautiful Purple Streets
We're so lucky here in South Australia to have some absolutely magnificent jacarandas growing throughout our beautiful capital city, Adelaide, and now would have to be one of my favourite times of the year to visit there.
My family seems to think I'm not particularly confident driving around the city (and that's not a lie!). Poor Mum! đź¤
And I'm not about to argue with them because, in all honesty, while I can get away with having someone else do the driving so I can sit back, gaze out the window to admire the trees... I'm going to make the most of it!
Over the coming weeks their enormous spreading canopies become covered in masses of trumpet-shaped flowers, then as the flowers begin to fall, the footpaths, lawns and roads beneath them become absolutely blanketed in a sea purple.
Honestly, it's worth the trip to Adelaide just to see them!
Some of the nicest places to admire them are around suburbs such as Unley, Goodwood and parts of North Adelaide.
Thinking of Growing a Jacaranda?
Before you race off to the nursery with visions of purple flowers dancing in your head, there are a few things worth considering:
Jacarandas are BIG trees!
Given the right conditions, they can reach around 10–15 metres tall, and some, with an equally impressive spreading canopy.
But that's part of their charm!
They're not really a tree to squeeze into a tiny courtyard or plant a couple of metres from the house.
Give them room to spread, develop that lovely open canopy and become the magnificent feature tree they're destined to be.
What Makes a Jacaranda Happy?
Fortunately, once established, jacarandas aren't too demanding.
A few preferences they do have though:
Sunshine:Â Full sun is ideal. The more sunshine they receive, the better their flowering potential.
Soil:Â They prefer well-drained soil and won't appreciate sitting with wet feet, particularly during winter.
Water:Â Young trees need regular watering while establishing. Once mature, they're reasonably drought tolerant, although they'll appreciate a good deep drink during prolonged dry spells.
Feeding:Â A little compost and organic mulch around the root zone is generally plenty. Avoid overdoing high-nitrogen fertilisers, which can encourage leafy growth at the expense of flowers.
Pruning:Â Less is more! Allow them to develop their natural shape, removing damaged or poorly positioned branches while they're young rather than heavily pruning mature trees.
And remember, those lovely spreading roots need space too, so keep them well away from underground pipes, paving and foundations.
But What About Our Frosty Winters?
Ahhh, now here's where we need to be a little careful, particularly here in the Limestone Coast!
Jacarandas originate from warmer parts of South America and, although established trees can tolerate the occasional light frost, young jacarandas are considerably more frost sensitive.
If you're determined to grow one, choose a warm, sheltered position, preferably protected from those southerly winter winds.
A north-facing position with plenty of sunshine and some protection from nearby buildings or established trees may help create a more favourable little microclimate.
Young trees can also benefit from frost cloth during particularly cold nights, along with a generous layer of mulch to help protect their root zone.
And even with all that care, severe frosts can still cause significant damage.
In our colder inland districts like Naracoorte where I am, a jacaranda will always be a little more of a gamble than it is in Adelaide.
A Few Things Worth Knowing
As beautiful as they are, jacarandas do have a slightly messy side!
Those beautiful flowers eventually fall, followed by leaves and woody seed pods, so they're not necessarily the ideal choice directly above a swimming pool, outdoor dining area or frequently used pathways you'd rather have remain clear.
But hey, that's a small price to pay!
Jacarandas can also take several years to begin flowering, so don't be thinking it's anything you've done wrong or something you've neglected giving them (providing you've done everything else right).
Patience is one of the wonderful things that gardening teaches us.
Planting a tree isn't always about what we'll enjoy tomorrow, sometimes it's about creating something beautiful for the years, and generations, to comeđź’ś

One of Australia’s most misunderstood garden legends: the blue-tongue lizard.
Now despite their tough-guy act, blue tongues are absolute sweethearts when it comes to our gardens and ecosystems. They’re not aggressive, they don’t want your lunch, (mind you they’ll snack on the cats food if you leave it out) and they’re certainly not plotting your downfall, they’re just doing an important job and hoping we’ll leave them be.
With climate patterns shifting and drought becoming a more common reality for so many of us, as gardeners we’re faced with the new challenge of how to keep our gardens thriving with less water.
Gardening during dry times isn’t about giving up and accepting defeat, it’s about getting smart and creative. By embracing some simple alternatives, our gardens can become more resilient, sustainable, and beautiful than ever.
