Sydney Seasons

At this time of year, for the last two years , there has been media reports about a concept championed by Dr Tim Entwistle. He's the executive director of the Botanic Gardens Trust in Sydney. Through studying the botanical environment around him, he's concluded that the traditional European classification of seasons is not suited to Sydney, and that we should have at least five seasons. He suggests seasons based around the chart above, with two month Autumn, Winter and Spring; a new two month season before summer, and a four month long summer.

Anyone with a garden would probably agree with him, as most flowering non native plants start to flower in August, which is the traditional winter.
