Spring has sprung at Australian Botanic Garden, Mount Annan | Gallery

The weather is warming up and that can only mean one thing - spring has well and truly sprung.

With the season kicking into gear the Australian Botanic Garden, Mount Annan has a host of displays and garden beds that are in full bloom.

Denise Ora - chief executive of Botanic Gardens in Great Sydney - said it was a fantastic time to take in some natural beauty in Macarthur.

"Just in time for spring, the Connections Garden has been expanded by over 650 square metres to include an array of native flowers showcasing Australia's diverse flora," she said.

"The main feature of the expansion is the newly designed five-metre tree sculpture and sandstone paving that serves as a landing.

"This is the perfect spot to take a selfie or take in the rolling hills of the Garden."

Ms Ora said the Connections Garden provided a great chance to enjoy the state's most famous flower.

"Usually hidden within the landscape of the Connections Garden, the red and white waratahs are a stand-out feature that are in full bloom right now," she said.

"From there I would encourage visitors to explore the Arid Landscape collection nearby that also provides a stunning view of the Mount Annan summit.

"On the way back down you can spiral into the Australian rainforest collection and lose yourself withing the cooling canopy."

The Garden is also home to the popular paper daisy display, which is once again drawing strong crowds keen to take a selfie. Visitors are reminded not to venture into the garden bed to get their Instagram-worthy shots, as that damages the flowers for the rest of the season.
