Woody pear trees grow in profusion in the uncleared bushland at my work. The summer view from the potting shed is delightful, snowy white cloaking the brilliant green foliage.
Jarrah trees are flowering now throughout Perth, the Hills and into the South-West as far south as Bremer Bay. These majestic trees can grow more than 400 years and cloak themselves in cream blossom every spring.
As Christmas approaches, the orange flowers of Nuytsia floribunda are a brilliant sight throughout Perth and the southwest. They’re called Christmas trees for the timing of their flowering, and are so much better than the fir Christmas tree people decorate. Nuytsia decorate themselves in a golden Christmas glow.
Macrozamia fraseri and Macrozamia riedlei are types of Cycad. The Cycadales Order is an ancient group of plants that have lived since the Permian era, more than 200 million years ago.  Australia’s Macrozamias could have been eaten by dinosaurs! I knew them as Dinosaur Plants when I was a kid.
Parrot Bush is a beautiful plant flowering now in bushland across Perth. I always think the flowers seem like they open with a loud pop! This prickly shrub grows as far north as Geraldton and into the southwest to Albany.
Swamp Banksia grows in and around wetlands, lakes and rivers throughout the Swan Coastal Plain and the Darling Range. It’s common at Lake Gwelup. Some have been planted in revegetation projects eg. along the boardwalk. Others are original vegetation, like this enormous tree on the east side of the lake which is countless years old.
Banksia menziesii is currently painting the bushland in hues of pink and yellow. Flowers range from pink and red through orange and coppery shades to brilliant yellow.  Some plants always flower yellow, some always pink, and some start the flowering season yellow and as winter temperatures drop, later opening flowers tend toward pink and red.  This tree at Richard Guelfi Reserve (below) always has yellow flowers. Behind it is a pink flowering Banksia menziesii.
The end of summer marks the start of marri flowering season (Corymbia calophylla). You can see their pretty white or pink flowers throughout Perth and the south west from now through autumn. Many birds and insects depend on the nectar and pollen of marri during the long flowering season. 
In early winter Templetonia retusa flowers and sets the bush aflame with scarlet, hence the common name Cockies Tongues. This many branched shrub grows in coastal areas on limestone from Shark Bay southwards, to Esperance and into South Australia.
