It is wattle time on the Koo Wee Rup Swamp. I believe the local species is the Black Wattle (acacia mearnsii). It grows anywhere, it lines the Swamp roads and also the Main Drain from Bunyip to Koo Wee Rup and if you dig up any soil and leave it for a few weeks you will soon have black wattles growing. The trees are neat enough when they are young, but after a few years they get messy, branches break off and they begin to look a bit ugly.
They are a bit slower coming out this year, but I took these photos on July 31, 2011, and they show how lovely they are.
The flowers of the Black Wattle are a pale yellow, not nearly as pretty as the Cootamundra wattle (acacia baileyana) or Australia's floral emblem, the Golden Wattle (acacia pycnantha benth) but from late July to the first few weeks of August the Black Wattle is glorious - they line the roads and the drain banks and you can look across the paddocks and see glimpses of yellow everywhere. It really is a magnificent sight.
Another common plant are the reeds (phragmites australia), they grow everywhere on the Swamp, where there is a bit of water. This photograph, above, was taken also taken in Dessent Road.
You can also see the reeds in the photograph, above. It is part of a series of post cards produced for Koo Wee Rup in the late 1940s or early 1950s. I think that's a blackwood wattle (acacia melanoxylon) behind the bridge.
William Wordsworth may well have been inspired by a host of golden daffodils, but to me there is nothing better that a host of golden wattles, brief though their time of glory may be.
