The project, funded through the Good Friday Appeal, began as a pilot program six months ago, and many crops – planted by and cared for by RCH ­patients and their families – are now ready for harvest.

RCH executive chef Andrei Kononov said: “We’ve stopped ordering thyme completely … with many of our chefs in the habit of regularly visiting the garden to check for produce.

“With more than 500 inpatient meals plated up each day, the program is already having an impact.

“Homegrown produce tastes much better, so patients are far more likely to consume it, ­especially when they have a connection … having looked after or harvested the produce.”

The RCH plans to continue the pilot program and grow seasonal produce that can be used throughout the year.

The project is linked to an RCH garden therapy program to help kids learn new skills, manage their emotions and enjoy respite from their treatment.

“Time in nature has many benefits, and has been found to improve mood, reduce stress and increase a person’s overall wellbeing,” RCH therapeutic garden co-ordinator Kayte Kitchen said.

“The impact it has on our young patients is incredible.”

For young Olena, 8, the therapeutic garden program is helping her self-confidence to slowly bloom.

Olena has transverse myelitis, an inflammatory disease of the spinal cord.

The condition, uncommon in children, causes loss of muscle strength and sensory symptoms like “pins and needles”.

Her mother Jess and ­father Rick said toiling in the garden was important for their daughter’s healing journey.

“It’s a way for Olena to do occupational therapy, using her muscles, hands and arms, without knowing she’s doing it,” Jess said.

“To be a part of nature, forget about all the medical stuff for a while and have fun in the garden … it puts her mind in a different place.”

Jess added: “It makes Olena more confident knowing she can do so many different things. Being in the wheelchair chair doesn’t restrict her.”

RCH chief executive Peter Steer said: “A hospital experience can be tough, but we want children to be children, and our garden space gives patients the chance to stay in touch with what makes them special.”

The Good Friday Appeal, also supported by Channel 7, has raised an extraordinary $468m. Last year’s raised $23m.

Funds raised by the appeal will further transform care at the hospital by supporting vital programs, research and equipment.
