Gardening tips: Combination Planters

The silver-red foliage of the Heuchera ‘Sugar Plum'

A garden is a treasure no matter how big or small it is

When we think of colourful containers and displays in our gardens, it is often that our minds will drift off to beautiful, boisterous blooms instead of the foliage of a plant. There are several stunning combination planters which can still provide a show of colour without the need for prominent displays from flowers.

One of my favourite ways to introduce colour into the garden is to utilise plants with attractive foliage. Often when making combinations, I look for leaves which have vibrant colours and intriguing textures. By checking these two simple points off your checklist, you are one step towards creating a stunning display for your garden.

Pictured above, is one example of the many containers I have made for my garden, which provides colour all year round due to the selection of perennials used. The silver-red foliage of the Heuchera ‘Sugar Plum’ gives the combination of a different look throughout the day depending on the position of the sun. The change of light against the foliage can be very variable. From late Spring through Summer tall stems of petite white blooms form above the red foliage giving the planter another level of interest through the season.

Paired with the Heuchera in this container is the silver trailing leaves of the Dichondra ‘Silver Falls’. Using a form of white in a combination display is a must as it will always make any other colour in the container more vibrant. Dichondra is an excellent plant as it provides a cascading appeal to the container and does a great job of picking up the silver-tones found in the Heuchera leaf, thus drawing the eye to investigate the whole planter.

Lastly, for a splash of colour is the vibrant blue of Lobelia ‘Sky Blue’. The petite blooms are the finishing touch without overpowering the whole display. Red and blue are my go-to colours, along with purple and orange. Using primary colours and a secondary colour together will always provide a satisfying contrast.

If you are unsure which colours work well with each other, a good tip is to refer to the colour wheel. Opposite colours usually provide the most dramatic display and contrast. A few examples of this exercise is pairing yellow with purple and blue with orange.

Combination containers don’t have to be limited to just ornamental perennials. Incorporating edible plants such as strawberries, herbs, and dwarf fruiting vegetables allows you to create not only an appealing display but a practical one too. A question often posed is why plant an annual vegetable in a mixed container? Well, they might only last you a season, but the beauty of planting dwarf vegetables is that they will gift you fruit and then at the end of the season the planter can be changed and re-planted for a completely new look. The options are truly endless! Whether you choose to grow ornamentals or edibles, you can draw inspiration from combinations just like this one and create your very own masterpiece.

Who were your mentors?

I was fortunate to be mentored by generous and knowledgeable members of the Australian Walnut Industry Association, who openly shared their experience and encouraged my growth in the field. In my research work, I have benefitted greatly from the world-class facilities at the Gulbali Institute at Charles Sturt University. There, I was mentored by Professor Sandra Savocchia, an exceptional researcher whose guidance shaped much of my learning. I was also supported by a multidisciplinary team with expertise in plant pathology, biochemistry, and molecular analysis. I truly could not have asked for a better group of mentors. Throughout this journey, my husband David has been a constant source of support and encouragement, making it possible for me to pursue my studies and research wholeheartedly.

What are you working on at the moment?

At the moment, I am working on a project that supports sustainable hazelnut production in Australia. Funded by AgriFutures Australia, the project has several themes and involves collaboration between several universities across the country. My role is within the sub-theme led by Professor Sandra Savocchia and focuses on evaluating potential disease threats to hazelnut production, including biosecurity risks linked to the import of plant material. The project also provides producers and nurseries with relevant information on disease management strategies to help minimise yield loss, and identifying areas for future research to ensure the long-term sustainability of the industry.

What does an average day consist of for you?

An average day for me starts with a cup of coffee and ABC classic FM in the background. After breakfast I check emails and respond to queries from nut growers, making sure they have the support and information they need. I usually set aside time to read the latest research updates on walnuts and hazelnuts, keeping up to date with developments in the field, and I continue working on writing and refining my research review. I also enjoy spending part of the day in my reasonably sized garden, tending to the fruit and nut trees. David and I try to fit in a daily hour’s walk around our quiet neighbourhood when the weather (and his kayaking schedule) allows. And although I’m no longer a full-time grower, harvest season is still special. During that time, we help friends in their orchards and share in the simple joy of harvesting together.

What is your favourite plant?

My favourite plant is the walnut tree. Beyond its value as a crop, it carries several fascinating mythological connections. In Greek mythology, the walnut tree is associated with Dionysus, the god of wine and ecstasy. He fell in love with Carya, the youngest daughter of the king of Laconia. When Carya’s jealous sisters tried to keep the two apart, Dionysus turned them into stone. Overcome with grief at their fate, Carya died of sorrow. Heartbroken, Dionysus transformed his beloved into a walnut tree, creating a lasting symbol of his love for her. For me, the walnut tree is more than a source of food – it is a living reminder of the beauty of love, the depth of loss, and the enduring power of myth.

Where do you see yourself in 5 years?

In five years, I see myself continuing to contribute to research that supports healthy, productive and resilient nut orchards across Australia, and helping growers access the knowledge and tools they need to manage emerging challenges with confidence.

What are your 3 most worthwhile tips that you can give to women who are starting out in the horticulture industry?

Build strong on-the-ground experience. Practical knowledge is invaluable and will shape your confidence and decision-making.

Follow your passion and don’t be limited by stereotypes. Be willing to challenge traditional expectations of women in primary production; your skills, interests and ambitions define your path.

Stay flexible and open to new directions. Horticulture offers many avenues, so don’t hesitate to explore different roles, learn new skills, or take unexpected opportunities as they arise.
