Knowing your climate zone will help you decide the best time to sow the vegetables, herbs and flowers you want to grow, and which varieties should perform well in your garden. Growing plants that are suited to your climate zone will usually give you the best results in your garden.

How to Use Climate Zones

First, find your climate zone using the map or descriptions below. Next, refer to our sowing chart, which provides approximate sowing times for our most popular seeds for each climate zone.

While knowing your climate zone is helpful when planning your garden, there are many other factors that may affect how your plants grow, including unseasonal weather conditions, the specific microclimate of your garden and how you care for your plants. You know your garden better than us, so if a different climate zone seems to ‘fit’ your garden better, go ahead and use it as a guide.

Our climate zones cover huge areas of Australia, so we recommend gardeners also consider their local conditions when planning what and when to plant. For example, gardeners in alpine areas have shorter growing seasons than gardeners in cool coastal areas, even though both alpine and coastal areas are included in our ‘Cool Temperate’ climate zone. We recommend gardeners in cool regions look at the ‘days to maturity’ information provided for each variety and choose those that will mature in a short (6-12 week) growing season.

Climate Zones FAQ

What if I can’t find my climate zone?
If you can’t locate your zone from looking at the map or the descriptions on this page, we suggest that you think of an area that has a climate that’s similar to yours and use the zone for that area as a guide.

What if I live on the border of two zones?
If you live near the border between two zones we suggest you read the descriptions for both zones and decide which best describes the climate where you live. Depending on the microclimate in your garden, you may be able to grow a wider range of plants over a longer season than others in your zone. Lucky you!

What is a microclimate?
A microclimate is a small area where the temperature or humidity differs to the climate of the surrounding area. For example, if you live in a climate zone where frosts are common but your garden is protected by buildings or large trees, your garden may be frost-free. Similarly, if you live in a warm temperate zone but your garden is at a high altitude your microclimate may have more in common with the cool temperate zone, so use this as a guide when deciding which zone is relevant to you.

Can I grow varieties not listed for my climate zone?
While our climate zones and sowing chart will help you decide what is suitable to plant in your garden, they provide general guidance only. We recommend you start by sowing seed that’s recommended for your climate zone; once you get a few successes under your belt you can experiment with varieties in neighbouring zones and see how you go – gardening is all about experimenting after all!

Description

Potato Onion (Bulb)

Allium cepa var. aggregatum

NOT TO NT, TAS, WA

Easy to grow

Mild onion flavour

Each bulb produces 10-12 new bulbs

A easy to grow onion, to 40cm tall and producing clumps of 10-12 bulbs under the soil's surface. This Australian heirloom variety from the late 1800s is often referred to as a 'perennial' because bulbs can be left in the ground to reproduce and it is also easy to lift, save and replant the bulbs year after year.

Bulbs are the size of small onions with a flavour somewhere between onions and milder shallots; they can be used in place of shallots and roast and caramelise well. The tops of the green leaves can also be eaten like a spring onion, leaving at least half the height to provide energy for the bulbs to grow. Bulbs store for 6-8 months.

Also called 'hill', 'mother', 'multiplier', 'pregnant', 'nesting' or 'underground' onions.
