The hairs are naturaly made by the plant and are called trichomes.

The "hairs interfere with the feeding of at least some small herbivores and, depending upon stiffness and irritability to the palate, large herbivores as well. Hairs on plants growing in areas subject to frost keep the frost away from the living surface cells. In windy locations, hairs break up the flow of air across the plant surface, reducing transpiration. Dense coatings of hairs reflect sunlight, protecting the more delicate tissues underneath in hot, dry, open habitats. In addition, in locations where much of the available moisture comes from fog drip, hairs appear to enhance this process by increasing the surface area on which water droplets can accumulate." wikipedia

The stinging spikes of stinging nettles are also a type of modified trichome which is pretty cool

I think it would be too much effort to try and train an old shrub into a tree when hydrangeas are so insanely easy to take cuttings of, and the cuttings grow so fast. (So much so that when we prune our hydrangeas many of the fallen branches accidentally become new plants).

tho I love hydrangea bush's too and this is a lovely mature one. So I reackon you should keep this one, take a cutting, and grow the cutting into a tree somewhere else, and then you get the best of both worlds (:

MRS GREEN would still exclude viruses as being alive. As viruses can neither respirate nor reproduce without a host cell and they can also not grow.

I'm weird and think a virus in a system of virus + host cell, is a part of the living cell, even if its a detrimental self-serving part.

Yes but I suppose life by its simplest definition could also be described as an effect from a reaction, rather than a thing, making the living object (the thing) simply a vessel for the reaction. So I suppose the whole fire system would be "the thing" in this scenario.

 

MRS. C GREN (Movement, Respiration, Sensitivity, Cells, Growth, Reproduction, Excretion and Nutrition.) is an acronym I learnt at school to categorise things as living or non-living. If something does all of these it is considered alive.

My teacher told me cells are included to categorise fire as non living (as fire fulfills all other requirements).

Even after finishing school I am still annoyed by this requirement. Cells are the basic unit of life. So cells need to be alive to be cells, but you also need to have cells to be alive, in other words you need to be alive to be alive, not very useful for determining if things are living or not.

So I propose an amendment, remove C and add E - for ability to Evolve. Fire cannot evolve, but I see evolution as an essential requirement for all forms of life.

Much more elegant.

Also as a bonus, MRS. GREEN is a nicer acronym and I think its easier to remember.

Were you taught a better acronym? Or perhaps do you have an even more elegant idea?

That's gorgeous! looks a bit like some kind of flying insect.

boiling water is the only method I know of that doesn't leave any contaminants, though I never found a need to bake them.

I just plop my substrate in a bucket with boiling water in it, then give it a quick stir before spreading it thinly on a mat allowing the hot water to evaporate off, leaving the substrate dry.

If you flip it upside down, placing soil in the lid with the container resting on top, you can make a mini terrarium like setup for micro greens. Then you can drill wholes in the lid to allow for draining and place it on a saucer. (I have done this for a couple containers and it works)

Sorry for the late reply and thanks for the question,

The Australian 2024 national defence strategy says this: "Our Alliance with the US remains fundamental to Australia's national security. We will continue to deepen and expand our defence engagement with the US, including by pursuing greater scientific, technological and industrial cooperation, as well as enhancing our cooperation under force posture initiatives"

US has these military facilities in Australia (and more secret ones):

"Australian Defence Satellite Communications Station – located near Kojarena 30 km east of Geraldton, Western Australia. Other U.S. bases in Australia are present and this list does not include ADF bases with U.S. access. The U.S. military has access to many ADF training areas, northern Australian RAAF airfields, port facilities in Darwin, Fremantle, Stirling naval base in Perth, and the airfield on the Cocos Islands in the Indian Ocean." Wikipedia

US also has a Rotational U.S. Army, Navy Presence where they bring their submarines and provide financial benefits to many military services they can use (RAAF bases and the assisting in manufacturing of missiles and other weapons). There are 2500 US marines on permanent rotation

According to US gov "The United States is Australia’s defense goods and services partner of choice" and "The U.S. has over $27 billion in active government-to-government sales cases with Australia" most of Australias military equipment comes from the US including their nuclear submarines

Also most aggregiously

"As documented by CIA whistleblower Christopher John Boyce and several authors, including John Pilger,[7][4][6] as well as some Australian politicians,[8] the CIA allegedly backed Governor-General and representative of Queen Elizabeth II in Australia, Kerr, to dismiss Whitlam, due to Whitlam's perceived left-wing policies[3] including Australian withdrawal from the Vietnam War, as well as his views on Australian sovereignty.[3] His conflict with the CIA is alleged[3] to have come to a head when he discovered several CIA-led operations occurring in Australia and overseas conducted by ASIO and ASIS, leading him to threaten cancellation of the lease on the Pine Gap facility, ending the US-led (nominally joint) operation, which was integral to the CIA's signals interception operations in the southern hemisphere"

"In a statement to parliament on 3 April 1974, Whitlam said: "The Australian government takes the attitude that there should not be foreign military bases, stations, installations in Australia."

He was then sacked and replaced by a more agreeing pm by the CIA Wikipedia

There are also numerous traid agreements that leads to Australia relying on US for a lot of its financial security (though it relies on China and Japan as well). And also many Australian companys are US owned/funded

This is all the research I have time to do but there are many, many more examples of American interference and control.

Edit: also America controls most of Australian media including News Corp Australia (owns most newspapers and News Corp is also the controlling shareholder of Foxtel and it owns Sky News in Australia. And much more)

also the American controlled ABC is the most visited site In Australia. And controls a lot of other media

What a cute little vacuum cleaner

I mean if you chose a bamboo variety that loves it outside but hates it inside then it will be a big challenge to keep them alive inside (most bamboos you see growing outside won't like it inside)

My Earina Autumnalis orchid flowered I have also got lots of other plants Im proud of, but I'm away from home so this is the only photo I've got.

Your terrarium is looking beautiful! I'm planning on making a large cooled terrarium for alpine plants sometime. All my current tereriums are small so it will be quite a challenge.

Wdym Australia last, they are practically controlled by the US already

 

About a year ago I rescued a native Earina autimnalis orchid that had fallen on to the road. I placed it on a tree with some sphagnum moss behind and watered it occasionally.

I was worried it wasn't happy, but then new shoots started growing, and before I knew it, flower spikes emerged!

A conservation friend of mine, who has cared for native orchids, said she's never seen them flower in captivity. So I wasn't expecting much from the spikes.

Then today when I checked how the orchid was doing, It was flowering with some of the most beautiful flowers I have ever seen :).

 

Here's my current record for most ferns growing on top of each other!

A tree fern called a ponga (Alsophila tricolor) forms the base, growing on this tree ferns trunk is a hen and chicken fern (Asplenium bulbiferum).

Hen and chicken ferns grows little bulbils (baby ferns) on its fronds, when the bulbils are old enouph, they drop off to become a new hen and chicken fern.

These bulbils make up the final layer of ferns of my fern stack, making it a magnificent 3 layers of fern.

 

Dendrobium cunninghamii, in Puketi Forest, New Zealand. In full bloom :). Its indigenous Maori name is Winika and a Maori canoe (Waka) is named after it

"In the fork of the tree grew a type of orchid known as ‘te winika’ which blooms with masses of white and green star-shaped flowers, evoking the huia feathers worn by high ranking rangatira (chiefs). This led to the auspicious name being given to the waka taua, that served Maaori royalty for many purposes, from transport to ceremonial duties."

I found this while walking through the Bush it was on the track with its exuviae right next to it. They are bloody deafening at this time of year but I still love to see them. Unfortunately I couldn't get any photos with the eyes properly in focus (as well as the exuviae) and my dog was desperate to carry on walking so this is the best I got.
