Celebrate Mardi Gras with rainbow flag at Austrlian Botanic Garden, Mount Annan

The Australian Botanic Garden, Mount Annan is all about inclusiveness and making people feel welcome, and that commitment is now on show with a slice of brightness in the grass.

The garden has celebrated Sydney's Gay and Lesbian Mardi Gras with a fabulous rainbow flag painted onto some turf.

Christian Eckardt, the garden's team leader of education and community programs, said he was proud to work for an organisation that was so committed to inclusiveness.

"The Australian Botanic Garden is all about making sure people feel welcome and included, and this flag is another example of that," he said.

"We raised the idea and our CEO was happy to run with it.

"I'm really proud to be a part of this and love working somewhere that is so dedicated to inclusiveness and acceptance."

Mr Eckardt said while acceptance and celebration of the LGBTQIA+ community were growing, anything that could be done to further that acceptance was a positive move.

"It's great to be able to show our support outside that Darlinghurst, Oxford Street bubble," he said.

"Not everyone can make it to Mardi Gras in the city, so the rainbow flag is a great way to show your support and care."

The flag was pained onto the ground earlier this month and refreshed on Thursday ahead of the parade.

Mr Eckardt said environmentally-friendly materials were used and have had no negative effects on the surrounding nature and wildlife.

He said people loved heading to the garden to get unique pictures.

"We have a few things throughout the year like this, including our paper daisy display in Spring," he said.

"People come here to celebrate nature - it's great to see."

The garden also celebrated the lead-up to Mardi Gras with a special Seedlings Nature School session on February 19.

The early year's nature educators held a 'rainbow seedlings' session focussing on acceptance and inclusion for all, with plenty of nature-based activities, games and stories.

Barring significant rainfall - "which would still be great", Mr Ekhardt said - the painted flag should remain visible at the garden until the weekend.

The Australian Botanic Garden, Mount Annan is open 8am-7pm every day.
