I'm looking around this morning, and there is this weed with a deep velvet color and wonderful raindrops on it. I just jad to get a photo of it.
Later during processing I noticed that red spot on the opposing leaf. I think that may be a bug!
Another stereo shot from my floor and I've pretty much exhausted my the flora in my yard. Too much contrast and separation to be a very good anaglyph but the free view pairs are kinda neat.
Parallel on the top left, cross on the top right, and anaglyph on the bottom.

Echium plantagineum - also known as Paterson's Curse / Salvation Jane / Riverina bluebell / Blue weed / Purple bugloss. In times of drought the hungry stock will eat these pretty purple flowered plants that cover paddocks for acres..

Paterson's curse, introduced to Australia from Europe during the mid-nineteenth century, is Australia's worst broadleaf temperate pasture weed. Its high seed production (thousands of seeds per square metre), seed longevity of more than seven years and an ability to germinate at any time of year, given the right conditions, contribute to making it such a persistent weed.
Biological control of Paterson's curse started in earnest in the late 1980s after a court battle involving bee keepers and six agents have now been released. The first, a leaf-mining moth Dialectica scalariella, is widely distributed but has little impact. Of the remaining six, four are currently being actively redistributed across southern Australia.
The crown weevil (Mogulones larvatus) is the most damaging agent, often killing the weed outright on a large scale, at a number of sites in NSW, Victoria and South Australia.
The root weevil (Mogulones geographicus), the flea beetle (Longitarsus echii), the flower beetle (Meligethes planiusculus), and the stem-boring beetle, (Phytoecia coerulescens) are also established in all southern mainland states, the most promising of which are the focus of a nationwide redistribution program.

This is a propane torch. I use it to create a stale seedbed. That's a technique whereby one makes a seedbed and waters it to encourage the weeds to germinate. After a week or two, when the seeds in the upper layer of soil have germinated, you kill them and if you don't disturb the soil and bring up more seeds, the seedbed will be fairly weed free. Of course planting seeds disturbs the soil a bit, but at least there are very few weeds around the seeded line. There's a rule of thumb to the effect that a seed buried more than 7 times its largest dimension will not germinate. I'm sure there are exceptions, but it seems to work fairly well for weed seeds. Once you deplete the seeds in the top thin layer of soil there aren't any more weed seeds to germinate until you do a mechanical cultivation to a deeper level and bring up more seeds.
The propane generates a flame around 2500 F, and this torch puts out about 250,000 BTU/hour, about the same as a furnace for a medium size house (depending, of course, on what you might call medium sized). The 20 lb propane cylinder will last about 45 minutes at that rate, but that will cover about 3/4 acre.
Note the hearing protectors on the backpack frame. This thing is noisy.
I just used it on the carrot bed. I now seed the carrots, wait 5 days, then torch anything that's up. On the 6th or 7th day, the carrots are up. You don't crisp the weeds. All that is necessary is to heat them up to the point where the water in the cells boils and disrupts the cell wall. The plant then dies. At the hottest point of the flame, it takes less than 0.1 seconds to do that, so you can walk along the row at a moderate saunter. The heat doesn't penetrate the 1/8" of soil where the carrot seeds are planted, so they survive. The horizontal range of the flame is about a foot, depending on the size and number of the weeds it encounters on the surface. For a 2 foot wide seedbed I have to count on two passes to get the weeds. Weeds more than 2" high are resistant to the flame. Some people even use this when the crop is up high enough, since the crop will also survive if it is large enough and the flame exposure is brief enough. I don't tempt fate that way.
If you look carefully you will see that the propane cylinder on the backpack is mounted upside down. That's because this particular model of torch is designed to work with liquid propane rather than propane gas. Both types are available, but for large areas the liquid torch is preferable. The propane is a gas when it burns, so it has to be converted from a liquid in the tank to a gas. That conversion (evaporation) reduces the temperature of both the liquid and the gas. After 15-20 minutes of use, a propane tank supplying a gas torch is starting to frost up, and the output pressure is dropping. With the liquid torch, the liquid travels down the pipe to the little nose just in front of the torch (resting on the gravel in the picture) where the flame supplies the heat to evaporate the liquid, then burns the gas. With this system the temperature of the liquid in the tank stays fairly constant, so the pressure doesn't drop with extended use.
The tank is mounted by bungee cords and ratchet tie downs onto an aluminum pack frame. The pack frame comes with a belly strap to stabilize it while walking. I leave this unconnected because if there's a problem I want to be able to get this thing off my back as quickly as possible.
This is a specialized piece of equipment, not the garden torch you can find in hardware stores. (i.e. don't try this at home).
About a dozen botanists from the BLM and U.S. Forest Service descended upon the Wild and Scenic Rogue River to remove invasive weeds, May 21-25, 2018. Photos: Stacy Johnson, BLM
There is a weed invasion happening on the Rogue River, and the federal government is getting strategic about battling the threats to public land.
Two weeks ago, about a dozen botanists from the BLM and the U.S. Forest Service rafted the Wild and Scenic Rogue in remote southwest Oregon to spray, pull and wrench as many weeds as possible.
Yes, a weed wrench is a thing.
The timing of the river trip was key, going after the invasive plants when they are flowering and before most of the seeds come.
One noxious weed, Dyer’s woad, can have a thick taproot that extends 5 feet deep and has the ability to produce a lot of seed.
“One plant left on site could easily be a hundred plants next year,” said BLM botanist Stacy Johnson.
Hand or wrench-pulled weeds were bagged and thrown in the rafts to carry out, while others, like Japanese knotwood, can only be killed with herbicide.
In some areas of the Wild and Scenic Rogue River, of which the team covered about 35 miles, they found untouched weeds that were multiple feet taller than the botanists.
“There are always more invasive species than we have time, really, to remove,” said Johnson.
Scotch broom, French broom, Spanish broom, shiny geranium, yellow star thistle, knapweed, yellow water primrose and parrots feather are among the other noxious weeds removed by the BLM-USFS team.
If left to proliferate, the noxious weeds would outcompete the native vegetation, taking over the beaches, gravel bars and all the other features that make the river and surrounding wilderness distinctive. The weeds also affect wildlife by decreasing food options and water quality.
“There are a lot of non-native plants out on the river,” said Kailey Clarno, district botanist for the Forest Service. “We go after species that are making a large impact on the river.”

...but it's oh so pretty:)
I don't know what this is called. It came up after the turf was laid
The delicate mauve flower emerges from a case that looks like a Gooseberry.
Not sure what the dark spots are; it might have been super-saturated from rinsing perhaps. But I am happy with it how it came out anyways.

I braved the heat and ventured into the Boondal Wetlands in Brisbane today. I didn't see too much and almost overheated, but there was a weedy looking grass that I saw a lot of.
Besides shooting some on site where it was quite windy, I brought a piece home to do some more macros.
This is almost straight out of the camera, except for some small light level adjustment.
