Well, here we have all the pollinators: birds, butterflies and moths, beetles (lots and lots of beetles), flower wasps, bees both native and european, and various small animals, both mammals and marsupials. There are even some heaths, lilies and some underground-flowering orchids that are pollinated by slugs. Accordingly we have all the flower colours, with blue being the rarest. Different flower colours dominate at different seasons, cycling through the year to attract the dominant pollinators of the time. And some flowers only open at night, for moths and nocturnal beetles. Other flowers change colour and/or scent over several days, to attract different pollinators (Brunfelsia), or to indicate that a flower has already been done and is now closed for business (Honeysuckle).
