Sweet peas are one of the most fragrant and nostalgic flowers that can easily be grown at home. I’ve been growing sweet peas in my backyard in Brisbane for a number of years and have learned a lot!

I’ve put together this sweet peas guide below with information on the best time to grow sweet peas and where to buy pretty varieties for anyone wanting to get started!

When To Plant Sweet Peas In Australia

Sweet peas are a flower that likes a bit of cool weather, so if you have been wondering when to plant sweet peas in Sydney, the simple answer is in autumn, and the tradition is to plant them on March 17 on St Patrick’s Day. However, because many parts of Australia still has warm and even hot temperatures in mid-March, I would recommend planting your sweet peas up to a month later than St Patrick’s Day when the weather cools down. The flowers then arrive in early spring.
