Autumn in Rotterdam: a Tree Tour
I hardly have to tell the reader why it’s good to have trees in the city. They purify the air, they absord CO2, they make it slightly less hot in the summertime and they retain water after heavy rain showers.
And of course they also make things more beautiful. This decorative function is most obvious in two periods: spring and autumn. Trees that in previous months were fairly inconspicuously bare or green, suddenly burst out into a feast of color.
Now that the meteorological (and photographic) fall is over, this blogpost aims to give a small, totally incomplete, tour of Rotterdam in the fall of 2019.
Is it a plane?
Rotterdam is a true plane tree city. Like our so-called capital has its elms, Roffa can be proud of its plane trees. Including, of course the Lijnbaanplataan, almost-tree-of-the-year. But also along the singels (canals) there are beautiful old specimens such as this centarian on the green slope along Noordsingel.
But no matter how beautiful they are: a city with only plane trees would be a bit boring. Fortunately there are many other species to be found in Rotterdam. Like the honey locusts (gleditsia triacanthos) with the striking red seed pods that are surrounding Erasmus in the park in front of Saint Lawrence church since a few years.
I previously wrote an entire blog post about the liquidambar styraciflua, or the sweet gum tree, whose leaves can take on just about all colors of the rainbow except blue. Quite a few of them have been planted in Rotterdam in recent years. Every time I think I have enough pictures of this miracle tree I come across another one that makes me grab the camera again.
Another tree that is mainly shining in autumn is the ginkgo biloba, even though it usually limits itself to just one color: bright yellow. This exotic tree, originally from Japan, has a rarely used Dutch name, which translates as the duck feet tree. Looking at the leaves it’s not hard to see why. The ginkgo is one of the very few tree species with its own Twitter account.
China and India
On Leuvehoofd Park I came across the beauty shown below. Upon inquiry it turned out to be a koelreuteria paniculata, which in English has several names: goldenrain tree, pride of India, China tree, and varnish tree. This little park close to Erasmus Bridge was designed by Dutch garden architect Piet Oudolf, who is actually much better known for his work on the High Line in New York. I assume that he is also responsible for planting this varnish tree. Well done, Piet!
Less striking in terms of fall colors, but certainly a pleasant tree to spot is the Caucasian wingnut (pterocarya fraxinifolia). This one is located on an unsightly square on the Baan, behind the Health Service premises. That building was finished 1941; so most likely the tree is almost eighty years old.
The Slow Fall
The fall of 2019 was a bit later than usual. The discoloration started late and until well into November many trees managed to hold on to their leaves. For a change, that has nothing to do with global warming. On the contrary: the cause was in the calm autumn weather without extremes: no very cold or very warm periods. Furthermore, enough water fell from the sky and, very importantly: that big autumn storm, which blows away all the leaves in one swoop, did not show up.
Nevertheless, the beauty was more or less over at the end of November. Although a path that is completely covered with linden leaves still yields a nice picture.
