Western Australia is enjoying one of its best wildflower seasons ever, with tourists flocking to county areas to see flowers carpeting the state in colours so vivid that they can apparently be seen from space.

WA Scientist of the Year Professor Kingsley Dixon told Radio 6PR the flourish could be attributed to this year's wet winter.

"We've had splendid rain, and that's been the whole trick," Professor Dixon said.

"It's not necessarily been the quantity but the beautiful frequency that we've had downpours. That's where you get the carpets over hundreds of square kilometres, and you can just detect a bit of colour from space."
