Mrs Kinder said they spent about a year gathering and growing the plants, and it was a great way to meet other parents.
"It's just the whole community thing really, as much as the plants," she said.
People at the event also had the chance to relax at the cafe and enjoy homemade goods and coffee, as well as live music.
Mrs Kinder said they also had magazines and books for customers and some stayed for hours.
"The food's been amazing and we've had really good comments about the cafe," she said.
Mrs Kinder said they have already started planning next year's event and hope to include workshops on things such as composting and perennial borders.
Mrs Blackburn estimated they would have raised about $6000.
