Some of the region's rarest plants will become a special feature on the edge of the Southern Highlands Botanic Gardens.
A project to create the Endangered Ecological Community is set to begin in August.
Whitlam MP Stephen Jones was on hand on June 3 at the Botanic Gardens to announce funding for the special project.
The $40,000 initiative has received $20,000 from the Federal Government with the remainder of costs being met by funds raised by the SHBG board.
The funding will pave the way for a variety of endangered species to be planted on the Eastern edge of the Botanic Gardens precinct.
Mr Jones said he was excited by the progress made at the gardens over the past 10 years since the official opening in 2010.
"I've always been a huge supporter of the gardens," he said.
"When I first came here it was a bare paddock.
"It is now legitimately the eastern gateway to Bowral."
Mr Jones reflected on one of his first visits to the gardens when he, along with several other officials including the NSW Governor at the time Marie Bashir, each planted trees in the garden.
He took time out in his most recent visit to the gardens to inspect the progress of that tree, a Cabbage Gum.
Mr Jones said when he planted it, the tree was about a metre high. It now stands firm at about 10 metres tall.
"The Bunya tree planted by the governor back in 2010, will not reach its full glory for 100 years," he said.
"The Bunya Tree is a great symbol of the effort and foresight of the volunteers of today.
"People in 100 years time will walk through this garden and will benefit from that foresight and hardwork."
SHBG CEO Charlotte Webb said that latest $20,000 funding announced by Mr Jones would go towards the inclusion of several of the rarest native plants in the Endangered Ecological Community.
"This community will feature plants that would have originally grown on the property now occupied by the Botanic Gardens," she said.
"They are plants that would have been here before the land was cleared for farming."
Among the inclusion will be the Paddy's River Box Eucalypt Macathurii.
The Southern Highlands Botanic Gardens is located on the corner of Old South and Kangaloon Roads in Bowral.
It is open to the public seven days from 9am to 5pm.
The Botanic Gardens nursery, also located on the property and features plants grown in the gardens, is open on Tuesday, Thursday and Saturday each week, weather permitting.
