EVOLUTION of AUSTRALIAN WILDFLOWERS . . .

Evolution of our wildflowers, dramatic, fascinating, conside-
ring the harshness, isolation of Australia. Flowering is a means
of achieving, at appropiate time, fertilisation. This mechanism
plants use to produce seed for next generation.

Being voiceless, flowers evolved colours, shapes, patterns, scents,
distinctive looks, textures,appealing to myriad insects and birds.
It is intriguing, these features, we can only look on in awe, no
artificial world here, nature in all it's splendour, in the raw.

With strategies which have developed over millions of years and
isolation, most flowering plants have spread widely in this con-
figuration. Appearing in the most unlikely places, seashore to inland
plains, mountain tops, river valleys, adapting a suitable strain

The Australian climate, landforms, creating varied environments,
geology, sunlight, space, soils, water, very basic requirements,
adaptability, diversity all a key factor in these most remarkable
plants. Evolving over millions of years, even in the present time.

Ancient soils very poor, no plant life they could possibly sustain,
on close inspection, they are highly specialised systems of living
they do contain.mechanisms for reducing water loss in severe
drought, equipped to recover even after severe bush fires

Yet, thousands of species of plants, on what is on offer, thrive,
diversification and adaptability, the key in a remarkably
fragile environment, some present in all climates, tropical, tempe-
rate, wet, dry, we do have an obligation to help their survival,
the least thing we can do is try.
