How to Care for Native Flowers

Native flowers generally last longer than traditional cut flowers if you re-cut the stems on an angle, use lukewarm water, keep them out of direct sun, and change the water every two to three days. Most Australian and South African natives are naturally hardy, but a few small habits make the difference between a bouquet that lasts five days and one that lasts two weeks.

Here's everything you need to know to keep your natives looking their best, from the moment they arrive to the last stem standing.

1. Re-cut the Stems Before You Do Anything Else

As soon as your flowers arrive, trim 2–3cm off the base of each stem at a 45-degree angle using sharp scissors or secateurs. This removes any dried or sealed-over stem tissue and opens up a fresh surface for water uptake.

• Cut stems at an angle, not straight across

• Use clean, sharp tools to avoid crushing the stem

• Re-cut every 2–3 days for the life of the arrangement

2. Strip Any Leaves Below the Waterline

Leaves left sitting in water break down quickly and encourage bacteria, which is one of the main causes of flowers wilting early. Remove any foliage that would sit below the water line before placing stems in a vase.

3. Use Lukewarm Water (and Change It Often)

Most native flowers take up lukewarm water more easily than cold. Fill your vase about two-thirds full, and change the water every two to three days, giving the vase a quick rinse each time to remove any bacterial buildup.

If you've got flower food sachets, use them — they contain sugar for nourishment and an anti-bacterial agent that helps keep the water clean for longer.

4. Keep Arrangements Out of Direct Sun and Away From Heat

Native flowers hold up well in Australian conditions, but cut stems are more delicate than the plant they came from. Keep your arrangement:

• Out of direct sunlight

• Away from heaters, reverse-cycle vents, and fireplaces

• Away from ripening fruit (fruit releases ethylene gas, which speeds up wilting)

• Somewhere cool overnight if possible

5. Know Your Stems — Care Varies by Variety

Not all natives behave the same way in a vase. A few notes on the varieties we use most often:

• Banksia & Waratah — Very long-lasting; woody stems benefit from a firmer angled cut and even a small vertical split up the centre to help water uptake.

• Kangaroo Paw — Sensitive to cold water; use room-temperature water and expect 7–10 days of vase life.

• Protea & Leucadendron — Extremely hardy and can last two weeks or more; they also dry beautifully if you want to keep them longer.

• Flannel Flower — More delicate than other natives; keep well hydrated and out of heat, and expect a slightly shorter vase life (around 5–7 days).

• Wax Flower — Prone to dropping in dry heat; mist occasionally and keep away from direct sun.

• Wattle — Best enjoyed in the first few days; it's a shorter-lived native but worth it for the colour and fragrance.

6. Signs Your Flowers Need Attention

• Wilted or drooping stems — re-cut and place in fresh water immediately

• Cloudy water — change it and give the vase a clean

• Soft or blackened stem ends — trim above the affected section

• Dropping petals or leaves — check they're not too close to sun or heat

Frequently Asked Questions

How long do native flowers last in a vase?

Most Australian and South African natives last 7–14 days with proper care, with hardier varieties like protea, banksia, and waratah often lasting two weeks or more.

Do native flowers need flower food?

It helps but isn't essential. Flower food extends vase life by feeding the stems and reducing bacteria in the water, though clean water changed every few days works well too.

Can you dry native flowers?

Yes — many natives, including banksia, protea, and paper daisy, dry naturally and hold their colour and shape well, making them a great option for long-lasting arrangements.

Why are my native flowers wilting quickly?

The most common causes are stems sitting in dirty water, direct sun or heat exposure, or stems that haven't been re-cut since purchase. Re-cutting and refreshing the water usually revives them.
