5 Geranium Varieties to Grow in Australia

Discover the vibrant world of geraniums. There’s one to suit every garden and taste!

There are many different varieties of geraniums available in Australia.

Here’s a selection of the most popular geranium varieties that you might like to grow in your garden.

Geranium Rozanne



This lovely geranium has violet-coloured flowers that are quite spectacular and will appear right throughout the warmer months of the year.

This variety is also extremely cold-hardy so it will grow in most parts of the country. 

This plant will reach a height of 60 cm and a width of around 50 cm which means it has quite a controlled growth habit so it doesn’t need too much pruning.

It was voted as Plant of the Centenary by the Royal Horticultural Society.

Geranium Black ‘n White



This geranium is perfect if you like a little contrast in your foliage. The leaves are shades of green, bronze and purple and the flowers are white with lilac centres. These are adorned with faint black lines.

This is a herbaceous variety which means it will die back in winter and then regrow in spring, especially if you live in a colder climate. It can reach a height and width of 40 cm.

Geranium Summer Skies



This lovely variety has double blooms that appear on slender tall stems. The flowers are coloured in shades of pink and lilac with cream centres.

It’s another cold-hardy variety so it can be grown in most parts of the country.

It will grow to a height of 50 cm and a width of 70 cm.

Geranium Maderense



This is a particularly attractive variety with large pink single blooms that have deeper pink centres. The dark green leaves are huge and can reach a width of 25 cm.

This variety will bloom from late winter right through to December.

It prefers to grow in a semi-shaded spot where it gets protection from the afternoon sun. Geranium Maderense will grow to a height of 1.2 metres and a width of 1.5 metres so it’s quite a large growing variety.

However, it is a biennial plant, so it will complete its life cycle in two years.

Luckily, if you don’t cut off the spent flowerheads, it should self-seed so you can have a succession of new plants from year to year.

Scented Geranium ‘Citronella’



I love scented geraniums and have these growing in my garden. Actually, I started out with just one plant but had to prune it because it grew a little too tall.

Of course, I wasn’t going to waste those prunings, so I cut them into stem sections with a couple of leaves on the top and popped them into a couple of pots.

These stem cuttings all produced roots like I knew they would, and I now have two extra plants in the garden and a couple in pots.

Surprisingly, a couple of the cuttings even flowered while they were producing their roots.

What I love about these varieties is the delicious scent you get when you rub against or crush the leaves.

They are available in a number of different fragrances but citronella is my all-time favourite.

These Geraniums will grow quite tall, up to 90 cm, so you might need to stake them as the tall stems tend to fall over. However, you can control the growth by giving them a regular prune.

The blooms on these geraniums range in colour from lavender to pink.

One thing to mention here is that these scented geraniums are actually pelargoniums as the flowers have two larger upper petals and three smaller lower ones.

FAQ

What is the difference between a pelargonium and a geranium?

To tell the difference between a pelargonium and a geranium, you have to take a close look at the individual flowers. On geranium flowers, the 5 petals are all the same. However, on pelargonium flowers, you’ll notice that the two upper petals are different from the three lower ones.

What is the longest-blooming geranium?

Geranium Rozanne is one of the longest-blooming geraniums. It has gorgeous violet-coloured flowers that will appear en masse for many months of the year.

Does Australia have native geraniums?

There is one Australian native geranium called Geranium solanderi. It mainly grows in woodlands and alpine regions throughout NSW, Qld, Victoria, Tasmania, South Australia and Western Australia. It has tiny pink or white flowers and is regarded as a perennial herb.
