Growing Zinnias In Brisbane
Holding some of the zinnias I grew in my Brisbane garden bed this year!
I’ve been growing zinnias in Brisbane for a number of years now and the main reason I keep repeating is because it is a flower that seems happy enough in our full on spring and summer heat when not much else is. (You can see a past zinnia garden here.)
I wanted to make special mention of what I did this year because I’m so happy with the result. This variety is a cut and come again flower, so I’ve had hundreds of flowers come through and they’re still growing!
I’ve included more details of what I did below. And If you’re looking for other flowers to grow in Brisbane, check out my Seasonal Planting Calendar below too!

Growing Zinnia In Brisbane | Garden Bed Edition
Here’s a few details of what I did:
#1 - I decided to plant my seedlings a little earlier than usual (I planted them on June 29 so they would be seedlings when we hit spring). This worked well because they were already well formed when it started to get really hot in Brisbane. You can definitely plant zinnias anytime in Brisbane and Australia throughout spring and summer.
#2 - I decided to plant one seed tray/30 zinnia seeds all in the one colour only. I think that sticking to one variety makes for more impressive bunches. I chose the coral-pink Oklahoma Salmon as my zinnia of choice this year. This variety throws out a lot of different colours from hot pink to peach and they looked stunning as a group rather than boring.
#3 - I planted the 30 zinnia seedlings that I grew on my balcony into a big garden bed with a few other taller things (sunflowers and amaranth) dotted between so that they were a little shaded. To keep out possums and bush turkeys I made a makeshift fence (see below) out of chickenwire and garden stakes, and covered it over the top with netting from Bunnings which did the trick. Nothing attacked the seedlings!
Part way grown! This is the garden bed I was growing the zinnia in - I planted around 30 seedlings in amongst the foliage here.
The final result! This stunning zinnia variety is called Oklahoma Salmon and I bought the seeds from the lovely Wild Violet Flower Farm!
