Do they say that the bush is all greyness and gloom Why, the rainbow has lent every thread from its loom To weave into flower and shrub – Lilian Wooster Greaves The wildflowers currently on display in and around the Jarrah forest are nothing short of spectacular. This purple enamel orchid (Caladenia brunosis) found near the Department of Parks and Wildlife headquarters was one of the highlights. I’m sure more will follow soon!
No other plant is more closely linked to Australia than the Banksia (Proteaceae). As the different species flower almost sequential in the south-western part of the continent they are most reliable suppliers of nectar and therefore a vital part of nature’s food chain. Unlike many Banksia the Honeypot Dryandara (Banksia nivea) or Bulgalla is a grounddweller, and the striking flowers make bees, honeyeaters and even Pygmy Possums stop for its sweet treasures.
As soon as the cold, wet and stormy winter weather gives way to an increasing number of clear and warm days, we know the so-called season of conception or Djilba has arrived. This transitional stage that started a few weeks back is always accompanied by the emergence of wildflowers; rather hesitant at first with some yellow acacias, soon followed by more spectacular displays in the most striking colours of red, blue and purple. Although there is an abundance of wildflowers with different colours and shapes to be discovered, orchids spark one’s imagination most. With around 25,000 species orchids form one of the three largest groups of flowering plants in the world; in Western Australia alone more then 400 species – 413 to be precise – have been identified so far. Scientific recording started as soon as the HMS Discovery anchored in King George Sound in 1791, and the ship’s naturalist Archibald Menzies collected the first three species. For the local Noongar people orchids provided an important food source, as the starchy roots were roasted in hot ashes …
A few weeks ago, Liz Hardman posted some stunning Protea or Suikerbos flowers on what is one of my favorite blogs, Nature on the Edge. If you are interested in South Africa’s Cape Peninsula, the conflict between its native wildlife and humans, but above all excellent photography, I can’t recommend this blog high enough. Suikerbossies are iconic South African plants, and, although cultivated as cut flowers, don’t occur naturally in Western Australia. But what Proteas are for Southern Africa, Grevilleas are for Australia, Indonesia and New Guinea: both are part of the same family, with common ancestors growing in the super-continent of Gondwana tens of millions years ago. The wildflower season is not in full swing yet, but on a recent venture on the granite outcrops in Beelu NP I discovered the majestic Fuchsia Grevillea (Grevillea bipinnatifida) as well as the Sea Urchin Hakea (Hakea petiolaris), another member of the family, showing their flowers and delicate textures. Nectar abound, so time for the honeyeaters to star in the upcoming posts!
“I care more about Drosera than the origin of all the other species in the world” – Charles Darwin, Origin of Species Charles Darwin’s fascination with Sundews is no secret, and after elaborate experiments to unlock the mechanisms of those carnivorous members of the Kingdom of plants, he published his findings in Insectivourous Plants in 1875. And as Darwin wondered about the sensitivity of the tentacles and leaves, their reflexes and digestive powers, I’m continuously amazed by how the small and delicate Leafy Sundew (Drosera stolonifera) is so well adapted to the poor sandy soils of our Jarrah woodlands, patiently waiting to trap and devour the next unsuspecting insect.
The carnivorous Red Ink Sundew (Drosera erythrorhiza) grows on the poor soils of Western Australia’s south west. It is a tuberous species that survives underground during summer, and emerges in abundance after the first rains in autumn and winter. It supplements its limited nutrient uptake by trapping anthropods with its glandular tentacles, with the glistening drops of mucilage resembling fresh morning dew.
Makuru is blue, Makuru is wet. The rain keeps falling, and the forest is full with damp, musty smelling wood. Fungi start fruiting, rotting away trees and leaf litter, like this Beefsteak fungus (Fistulina spiculifera). Known as Numar by aborigines, it fruits on Jarrah (Eucalyptus marginata) trees, producing a slow decay in the wood called ‘pencilling’ or ‘black fleck’.
The Western, Gregorian or Christian calendar is the most used calendar in the world, with twelve months and four seasons dividing each year. This is no different in Australia, where it was introduced by European settlers. However, the Noongar of Australia’s South West use a six season calendar, based on the emergence of plants and animals rather than solar cycles or dates, and the seasons therefore can be longer or shorter. More importantly, the Noongar were guided by them, as they provided crucial clues and information for when to substainably hunt, gather and take care of country. Blue Leschenaultia (Leschenaultia biloba) Purple Flags (Patersonia occidentalis) When living in the forest we experienced the significance of the Noongar calendar, and realised how far city dwellers are removed from the natural world. Throughout the years I have mentioned and used the names of the Noongar seasons in several posts, but realised they were never explained within their context (courtesy South West Aboriginal Land and Sea Council): Birak (Dec-Jan) – Dry and hot – Season of the Young Bunuru (Feb-Mar) …
Last Saturday we battened down the hatches when a severe cold front hit Perth like a freight train, carrying destructive winds and dumping copious amounts of rain. No chance to go out on the trails, but excitement of things to come instead. Those early winter rains are essential for all future life, as this time of the year is called Makuru or the season of fertility in the Noongar calendar. This is the time of the year for birds to pair for preparation of breeding, like the Black Swan or Mali, and also the time for the first wildflowers, as the Pinheath (Styphelia tenuiflora), to emerge.
The Swamp Paperbark (Melaleuca rhaphiophylla), also known as tea tree or Yowarl, is a common appearance near rivers, lakes and salt marshes in the south west of Western Australia. Its name refers to the paper-like bark, and the long flaky strips were used by aboriginal people as roofing for shelters, carrying of water, cooking, medicinal purposes and smoking ceremonies. Most paperbark trees grow in flooded areas, providing the perfect refuge for the many water birds that share its habitat.
“Moreover the purchasers of plants will often be able, by a reference to this sketch, to ascertain, by the names under which Swan River plants are offered for sale, whether particular species are worth possession, either for the sake of their beauty or singularity” – John Lindley, A Sketch of the Vegetation of the Swan River Colony Even when the forest is eerily quiet, when not a single sound can be heard, in the Australian bush there’s always something new and interesting to discover, no matter how small. On a recent walk I found those beautifully red hairy jugflowers (Adenanthos barbiger), a species of the Proteaceae family endemic to south-west Western Australia. Apart from the esthetic aspects, I often find the botanical history of flowers and plants equally interesting, as it reflects the amazement of the early botanists and explorers when new species were discovered – species that now have become so common and sometimes even unremarkable to us. The hairy jugflower was first described by John Lindley in A Sketch of the Vegetation of the Swan Colony. …
Visiting some of our favorite Australian National Parks is not always easy as many of them are located in the northern part of the continent. Distance is not the major obstacle, as traveling just costs time and petrol, however, it is the climate that makes things complicated. In summer the tropical regions can be unbearable hot with temperatures exceeding 40°C, while the cyclones and heavy rainfall of the so-called ‘wet’ season hinder access to many areas. Unfortunately our leave is mostly taken during summer holidays with the result that many wild places are still on our bucket list. This is exactly why we’re so excited that finally we’re heading up north this July, to visit Karijini National Park in the Pilbara region of Western Australia; an outback adventure we have been dreaming about for many years! The Tall Mulla Mulla (Ptilotus exaltatus) we spotted around the Shark Bay area late last year will definitely be one of many attractions, as this magnificent wildflower is a true icon of the outback.
The Stirling Range National Park is a biodiversity hotspot with a dazzling array of wildflowers. Although most of the area’s iconic species flower in spring, there is not a single season when the landscape is not alive with colours, textures and shapes. A few walks or climbs on and around the numerous peaks unveil a true botanical treasure – as long as you’re able to focus on the little things instead of getting lost in Koikyenunuruff’s lovely vistas. The plants that populate the Stirling Range make it a special place, however, especially the rare montane heath and thicket is under serious threat: Phytophtora dieback disease, intense and frequent fires, climate change, as well as browsing by animals such as quokka’s (Setonix brachyurus), mardo’s (Antechinus flavipes) and quenda‘s (Isodoon obesulus) has led to severe population declines. Protective fencing for highly threatened species in order to allow regrowth has shown promising results – so don’t be surprised to find those fencing structures on top of Bluff Knoll!
The Candlestick or slender Banksia (Banksia attenuata) – also known by its Nyungar name Piara – is the most widely distributed western Banksia. It occurs on sandy soils from Cape Leeuwin to Fitzgerald National Park in the south-west of Western Australia and as far as the Murchison River and Kalbarri National Park to the north. In the latter we encountered numerous small shrubs with early budding, almost green spikes that slowly develop into bright yellow during anthesis – ready to attract insects, birds and mammals for pollination.
Each time I go out for a bush walk this time of the year I wonder which treasures nature keeps in store for us to discover. Because of the warm spring weather many plants and animals undergo a transformation; the flowering of the Moodjar or Christmas Tree indicates that hot weather is already underway, but before the season of Birak brings the wildflower season to an end the incredibly beautiful Myrtle flowers show off their purple splendour. And although both the Graceful and Rough Honeymyrtle (Melaleuca radula and Melaleuca parviceps) are most common it is the ostentatious Pink Flowered Myrtle or Kudjid (Hypocalymma angustifolium) that steals the show.
The Granite Petrophile (Petrophile biloba) is endemic to the south-west of Western Australia and mainly grows on the granite overlaying soils of the Darling Scarp. It is generally unremarkable, but when this shrub starts flowering in spring it displays pink, grey, white and yellow flowers arranged in a seemingly chaotic order only seen in works of Jackson Pollock – a cacophony of colours, shapes and textures that draws you in when engaging with it long enough.
The last few weeks have been a real wildflower carnival. With warm weather and still decent rainfall we have been watching a parade of colours and shapes unfold up in the hills. Although the participants in this parade try to outshine each other in the quest for pollinators, the striking Sea Urchin Hakea (Hakea petiolaris) is one of my favourites. This early flowering tree is mainly found around the granite outcrops where it benefits from increased moisture and shade, and because of its stem-flowering or ‘cauliflory’ habit, it is thought that the Sea Urchin Hakea is a relict of an earlier, wetter and more forested habitat.
The season of adolescence or Bunuru is well underway – the days are still hot with temperatures in the mid-thirties, warm easterly winds and little or no rain. Bunuru is also the season of flowering gums, and the Marri trees (Corymbia calophylla) surrounding our tree hut are in full bloom now – a truly spectacular sight!
When French naturalist Jacques Labillardière visited New Holland (Australia) in 1792 under the command of Antoine Bruni d’Entrecasteaux, the foundations were laid for what became the most extensive collection of Australian flora of its day and age. Especially his collections from southwest Australia produced numerous new species amongst which the ones from the genus of Anigozanthos, better known as Kangaroo Paws. His discoveries are described in the Novae Hollandiae Plantarum Specimen, a masterpiece of botanical science and art. I clearly remember my own amazement when I first saw those wonderful plants with their tubular flowers, dense hairs and claw-like structures. No wonder the State Government named the striking Red and Green Kangaroo Paw (Anigozanthos manglesii) as WA’s floral emblem in 1960, after which it was incorporated in the State Coat of Arms. Although this species is the best known and most famous of all Kangaroo Paws, the tall Evergreen Kangaroo Paw (Anigozanthos flavidus) and the much smaller Cat’s Paw (Anigozanthos humilis) are equally remarkable and spectacular.
The Australian Christmas Tree (Nuytsia floribunda) or Moodjar is not exactly known for its lights or baubles, but for its spectacular display of golden flowers that appear in Birak or the ‘yellow season’. The succulent roots, nectar-rich flowers and nutritious sweet gum of the world’s largest mistletoe are prized by the Nyungar, however, as the tree is thought to be inhabited by the spirits of dead people it is better left alone when not in bloom. So we are lucky to have another kind of Christmas tree around our place – and therefore would like to wish you all a Merry Christmas while it’s in full glory!
