She explains that the tree is a rarity in this part of New South Wales. This one in particular is more than a century old and heritage listed.

But that's not why it's her favourite place in her garden.

Basking under the shade of the pepper tree was her late husband Keith's most cherished place.

The spot is now memorialised with a beautiful stone bench inscribed with Keith's favourite quote.

"He loved the garden and he loved being here, so this is for him," Ursula explained.

"If he had his way every bit of the garden would be under this tree."

You soon realise walking through the gardens of 7a Thorpe Avenue that this riverside home as a whole is a bit of a memorial.

There's a zen feel to it. It's peaceful and relaxed.

It's an atmosphere the Reids strived to achieve when they purchased the bare block of land in 2001.

Now, the private and relaxed property will open its doors to the public for the first time on the weekend of September 27 and 28.

Known as the inaugural Keith Reid Memorial Open Garden and art exhibition, visitors can admire the soothing gardens as well as a number of Asian-styled sculptures from Humble House Gallery.

"It's basically in memory of Keith," Ursula said.

"That's the focus. It's not quite been a year since he passed but it means a lot to me, just being here and keeping it going."

Other attractions of the property include a riverside walkway, native ornaments, a waterfall, a number of heritage-listed trees and a propagation glasshouse.

Resident dogs, Tam the Doberman and Harry the Grudle will be more than happy to escort visitors.

All profits raised from the $5 entry fee will go to the HOME in Queanbeyan, a support network for people living with mental illness.

Doors open at 7a Thorpe Avenue, Central Queanbeyan between 10am - 4pm on the weekend of September 27 and 28 with refreshments provided.
