Irish native Aspen tree / Trembling poplar (Populus tremula/ tremuloides)
Aspen ... Populus tremula / tremuloides ... Crann Creathach
If you were to judge a tree by its common name, then this particular Irish native tree would confuse you. Populus tremula is commonly known as the aspen, which for me conjures up images of snow capped mountains and ski slopes in Colorado, an area that happens to enjoy a wide distribution of these trees.
So, to avoid confusion, I usually end up calling this tree by its other common name, which is derived from the Latin meaning, trembling poplar.
The whispering leaves.
This common name (Trembling poplar) is very fitting, because its loosely toothed, almost circular leaves (3 to 8 cm across) tremble in the slightest breeze. This leaf movement creates a distinctive and often spooky rustling sound, arriving out of nowhere on a calm day, as if whispering to the passers by. The down to earth explanation for this sound is that the leaves are light enough to be disturbed by a faint breeze, but coarse enough to create a rustling sound. However, this has not prevented the many legends associated with the trembling phenomenon.
It was believed that Populus tremula was cursed forever to tremble in shame, having been the wood used for the cross upon which Christ was crucified. I have my doubts about this story, as these aspen trees are native to colder regions with cool summers, which Palestine does not provide. Another legend assures us that the trembling poplar leaves are made from the tongues of past females, who had a great ability to talk and talk. I also doubt this legend, mainly for fear of crucifixion by all the masses of lady gardeners out there.
Catkins and insects.
Whatever about the legends, I can vouch for the leaves emerging coppery brown in spring, and then later maturing to grey-green with light coloured undersides. Being a deciduous tree, these leaves shed from the light branching in a rain of yellows and gold's throughout autumn. Before clothing itself with leaves in spring, the male trees produce flowers, which are hanging catkins (11cm long), greyish-brown in colour. On female trees, green and brown catkins of a similar length are produced, both of these catkins are part of the trees eco-system, which is known to sustain up to 90 insect species.
Ideal conditions for a quick growing shelterbelt.
Although not terribly prevalent in Ireland, Populus tremula can still be found on hillsides, deep in valley bottoms and on the edges of wooded areas. The trees preferred growing conditions are moist with a neutral to acid PH in full sun to semi-shade. As regards exposure, this poplar will tolerate strong winds all apart from salt laden sea breezes. It is worth noting that while the trembling poplar is often planted as a quick growing shelterbelt, 20 metres tall by 10 metres wide, it does possess an extremely aggressive root system. These roots have the ability under certain circumstances to damage building foundations within a 10-metre radius, and to create further poplar trees by means of root suckers.

Hi Kathy. If you can find some growing locally, you can propagate them from cuttings at the moment. You can use any size of cutting, from an 8" twig, to a 3' long branch. Simply plant the fresh cutting where you wish it to grow, for free. They take easily, and grow vigorously.
You missed a talk in Dublin on Tuesday by Charles Dowding the Guru of No Dig, you can check out his website and join the forum to ask questions.
But before you click do ask here as theres lots of knowledge, I know of 2 gardens in Ireland both in Dublin area and two that have ceased both in dublin so what does that say.

If I can add something to Greengage's last post, Dr W Shewell-Cooper was already well established as an advocate of 'no-dig' by the time he wrote his book in 1977. Dowding's web site claims he's been a 'pioneer' of the method since the '80s, so is clearly a bit of a con artist and preying on those with short memories who know no better? _________________ A novice gardener on newly cultivated, stoney ground.
Agree, there was a famous put down in American politics once and it could be used here.
"Republican Dan Quayle had his words used against him during the 1988 vice presidential debates after he likened his political experience to that of John F. Kennedy. Democratic opponent Lloyd Bentsen's response: "I served with Jack Kennedy. I knew Jack Kennedy. Jack Kennedy was a friend of mine. Senator, you're no Jack Kennedy." Quayle's miffed comeback — "That was really uncalled for, Senator" — had to wait until the laughter died down.
I met Mr Dowding and he did not invent the wheel that was back in 2011 I think he still promotes himself as only "they" can do.
Now Britian is outside Europe they will not have access to Brussels sprouts, Hamburg potatoes, or the cheap labour to pick them. so maybe the no dig campaign will take off again. On that subject where did GIY go to the holy grail that was going to make us self sufficient, now the tiger is back we will get our hands dirty again in a different way.

I won't comment on the Brexit matter but, on GIY, I became aware of it and looked a bit closer. All seemed fine until I noticed it was a limited company, at which point I backed off. This site needs a bit of advertising to help run it and I'm quite happy with that, but I rather think GIY was rather cleverly marketed to look like a God's Gift benefactor, but with profit in mind? _________________ A novice gardener on newly cultivated, stoney ground.
