On the edge of the storm, Tuesday evening…
I mentioned in a post recently that we have a lot of pollen this spring. (Understatement of the year!) Well, I have since learned that not only has everything flowered at once due to our warm April – the warmest on record since 1881 in Germany – but it is also a so-called mast year for birches, spruce and firs in our region.
A mast year is basically a year when certain types of tree in a whole region produce much more pollen and thus far more seeds than in a normal year. Birches do this regularly – every second year – while other trees such as oak or spruce only do this every 4-8 years.
Trees generally use their energy for putting on growth in non-mast years. But in a mast year something triggers them to put all their strength into preserving themselves and to produce as much seed (and hence pollen in spring) as possible. This can apparently be seen in the rings when a tree is cut, with intermittent rings of very little growth. The trigger may be a warm spring, drought or other factors such as the North Atlantic oscillation. In other words, climate change affects tree ‘behaviour’. But what fascinates me is that, for example, practically every Spruce tree in the whole of Germany has started pumping out the pollen, whether in the far north, the Alps, the Black Forest or the Bavarian Forest. Clever. 😉
Just looking across our valley at the hillsides around us recently it suddenly became clear to me that the Spruce, Firs, and probably many other conifers have joined the birch this year – the trees are gold and brown instead of green, with little fresh growth and millions of flowers and cones forming on their branches. Perhaps you can see what I mean from this photo taken yesterday where the conifers are all much darker than the fresh deciduous trees in full leaf…
In fact, when I walked around the garden and took a closer look I could see our Norway Spruce, Douglas Fir, Silver Fir, Austrian Pine and other conifers I cannot identify are all going mad this spring!
One article I read quoted a botanist suggesting the conifers are suffering from several dry years in a row, and this is a self-preservation measure should they die. A grim thought. While looking for more information on this phenomena I found myself engulfed in the technical jargon of meteorologists and botanists. But it was interesting to find out just why we are experiencing so much pollen this spring!
Have you ever heard of mast years or experienced the same where you live?
I planted a few tulips in pots last autumn, and the first ones to open were Tulipa kaufmanniana ‘Heart’s Delight’.
I have grown these for several years now, and find they don’t last many years in the ground, producing just leaves. So I decided to try containers for a change. They stood outside all winter, close to the wall on the north side of the house, and were basically ignored until I noticed them showing shoots!
I watered them sparingly and moved them into a sunny position. They started flowering about a week earlier than those in the ground.
They have dark green stripy leaves, which add to their attraction both before and after flowering. Sadly I have more leaves than flowers these days – this picture below of the spring corner was taken several years ago.
At first the flowers are mostly white, with an egg-yolk centre, but gradually they turn pinker and pinker – a kind of sunset orangey-pink. In the picture above you can see them at both stages. Delightful, don’t you think?
The name of this pretty little tulip reminded me of a wonderful song you may have heard of. And not only beacause of the title but also the singer! The English title is ‘You are my Heart’s Delight‘, but the original was German – ‘Dein ist mein ganzes Herz’. It is an aria taken from a Franz Lehar operetta and Jonas Kaufmann sang it at the Last Night of the Proms in the Albert Hall in London a few years ago. I have been smitten with it ever since! Here is a German version with Placido Domingo…
Or if you prefer to hear it in English here is Richard Tauber singing it; he was the man who made it internationally famous after its success in Austria and Germany. The lyrics are lovely in both languages!
Have you ever grown this pretty flower, or maybe a similar early tulip?
My first tulip ‘Early Harvest’ is out! These, unlike most other tulips, flower extremely early, long before the rest of the garden has had a chance to wake up. They are, however, 10-14 days later than usual this year. The contrast of the bright orange against the brown soil is uplifting to say the least!
I have also got another early tulip already showing… can’t remember what it is, but perhaps it will come to me when it opens fully.
As usual, things are moving along rapidly now that the hard frosts have given way to some mild damp weather, and early spring means the bees are HUNGRY… this little fella couldn’t wait for the bud of the Chionodoxa (‘Glory of the Snow’) to open, and just scrabbled around until he managed to open it himself!
The crocuses have also been attracting the bees…
These splashes of colour are so welcome, and I hope they brighten your day too!
Enjoy the Easter weekend, and hope you get SUNSHINE! 😀
(If you don’t like tiny creepy crawlies, I suggest you go and look at a different post!)
On our walks in the woods recently we have once again noticed little black specks on the snow. Until now we thought it must be dirt from the machinery used for forestry or from old tractors driving through the woods, but this year it was extreme and so we took a closer look…
Here we saw that where tracks are (from tractor tyres, deer, our footprints, skis etc) there is more of this ‘dirt’. Could it be soot? Is our air so bad? Here, in the middle of nowhere, with no industry for miles…
When we got home my Man of Many Talents googled for ages, trying to find something about it, and when he showed me what he had found I was AMAZED! He went back to get more photos so we could check the facts!
Now I’m going to get even closer…
They are SNOW FLEAS! Now, maybe we are the only people in the world who have never heard of snow fleas before, so I hope I am not showing my ignorance, but aren’t they simply incredible? Here are several hundred or even thousands of them gathering in the hollows of tracks.
Now a little information that we found in German, summarized:
Snow fleas come out of the ground in February/March when the temperature is just above freezing. They are often thought to be soot, as they cover the snow quite thickly in places. But these ‘specks of dirt’ are all the same size (around 1 millimetre long). They can crawl and jump (about 10cm high). However, they aren’t actually fleas, but springtails, so Wikipedia says they are technically not insects.
They emerge at temperatures of about -3°C, and live on fungi, pollen or algae which provide them with a special protein that functions as a kind of antifreeze. They prefer damp forests with evergreens. It is a real migration at this time of year, as they use the snow to move more easily and to search for food and for new ground where they can increase their population.
For scientific purposes my Man of Many Talents let some crawl across his hand, and we think they are actually smaller than 1 millimetre…
So, please let me know if you have ever encountered these fascinating little creatures and any extra information would be very welcome!
I have just finished reading this great book, recommended to me by Sheryl at Flowery Prose last November and immediately put on my Christmas wish list. You can read her review here, but I will add a few words too.
Hope Jahren is a scientist with a gift for writing, and the book flows right from the start. She recounts her life in an enchanting and extremely readable way, mixing in fascinating information and descriptions of trees, plants and her work. The story is full of ups and downs, telling candidly, passionately, and often hilariously of her (sometimes unconventional) struggles to set up labs, her discoveries, her dedication to her research, and the dear friend Bill who accompanied her through it all. Her style of writing is fluid and amusing, but also incredibly poignant when we note the hidden comparisons between the lives of trees and those of humans.
I really loved this book and wholeheartedly recommend it to anyone with a vague interest in trees, botany or science in general who wants a good weekend read.
Take a look at Sheryl’s review – she can say it so much better than I can!
This week we will not only see the second full moon within one calendar month, but also the third of four full moons for this season, making it a ‘blue moon’. This doesn’t happen very often – hence the saying ‘Once in a blue moon’.
Now, if only I had one of those lovely Chinese moon flask vases to use for my Monday vase as I join Cathy at Rambling in the Garden once again… but this round one comes pretty close:
Now, what can I put in it?! Well, after searching the soggy garden I did manage to find something suitable…
Some lovely long hazel catkins, a hellebore from the patio pots and some hellebore leaves, grasses, and a few sprigs of St John’s Wort that hasn’t died back at all this winter. The sparkly white candle is left over from Christmas (I couldn’t bear to light it as it is so pretty) and is included here to symbolize the full moon. 🙂
I also filled another small vase with a hellebore and some Heuchera – the tiny pottery vase was bought at the Christmas markets with snowdrops in mind, but the little green shoots of my snowdrops are only just showing…
If you are in the northern hemisphere, I wonder if you have got snowdrops yet?
Have a good week, wherever you are!
