The extraordinary structure of Western Australia's native plant seeds will be on display as part of this year's Kings Park Festival.

The festival, now in its 53rd year, is a celebration of the local wildflowers that blossom in springtime, and runs for the month of September.

Each year, Botanic Parks and Gardens Authority (BGPS) staff and volunteers spend thousands of hours planting flowerbeds, as well as developing other activities for visitors to enjoy.

Dave Merritt, senior seed scientist at the BGPA, told 720 ABC Perth the this year the centrepiece was a outdoor photography exhibit, titled Future Keepers, which aimed to provide new perspectives on the state's plant life.

"We are trying to highlight the diversity, adaptation and really quite amazing biology of our native seeds and their importance to our conservation activities," Dr Merritt said.

"We've had some graphic designers enhance them with colour, just to highlight some of the intricate details.

"What strikes me is just the intricate detail, the patterning on the surface, some the appendages, the hairs, the horns that some seeds have."

Although some seeds are smaller than a grain of sand and most go unnoticed by the general public, seeds are central to the work of the BGPA scientists.

"It's a little known fact that Kings Park has a seed bank, which has collections of seeds dating back to the 1960s," he said.

"We have 10,000 collections of about 3,500 species — about a quarter of Western Australia's flora.

"Seeds are how plants move through space and time basically, and they are really quite marvellous little packets of genetic information."

The seeds are saved not just for posterity but to further the work the authority does in helping to rehabilitate land damaged by agriculture and mining throughout the state.

"For the restoration story, we are talking about very large areas of land, hundreds or thousands of hectares," Dr Merritt said.

"The demand for seeds just continues to grow."

The Kings Park festival pre-dates the creation of the Gardens Authority and now brings around 600,000 people into the park every September.

Festival coordinator Deneka Simpson said in addition to Future Keepers, there were numerous free events happening across the month.

"We have the guided walks in the park which are always very popular," Ms Simpson said.

"This weekend we have a kids hair show called Mystérieuses Coiffures."

The show involves French "hair wizard" Christophe Pavia who uses native flowers to create headpieces, and then styles them directly into audience members' hair.



"We are flying some artistic people in from France to do some artistic things and really putting the spotlight on WA flora," Ms Simpson said.
