Cedrus - the cedars
Posted on December 9, 2013 by Ash
Autumn is once again a receding memory, growing dimmer everyday as we continue the inexorable slide into the darkest depths of winter… But try hard enough and it’s still possible to cast our minds back to a time when the trees still had leaves; when warm shades of gold, orange and red coloured the landscape; when the mercury didn’t sit so low in the thermometer.
This towering deodar (Cedrus deodara) grows close to the East Gate. It is a beautiful and imposing tree, one of the finest in the gardens.
Looking up into the hefty crown of the deodar - how many branches? How many growth points? What tonnage of timber?
A neighbouring big, old sweet chestnut (Castanea sativa) seems sadly to be in serious decline. The tree was rather sparsely foliated at the time of this visit, but at that point in the autumn natural leaf loss would have been premature. It’s a shame because it’s another fine tree. A major branch has a few old wounds on it, one of which sported a nice bit of fungus. It’ll be interesting to see how the tree looks in spring.
I came across these Pholiota squarrosa mushrooms growing at the base of a big European beech (Fagus sylvatica). They were also growing around the base of a nearby heartnut, a variant of the Japanese walnut (Juglans ailantifolia var. cordiformis). P. squarrosa is a parasitic white-rot fungus that attacks a wide range of host trees.
This mushroom was growing under a pine tree… …along with its wee pal.
This dawn redwood (Metasequoia glyptostroboides) in the Chinese Hillside part of the gardens was positively radiant. The needles - here so vibrantly illuminated - are now long gone, this being a deciduous species.
This oak really stood out from the crowd!
A nice cider gum (Eucalyptus gunnii) growing in front of the 1960s glasshouses. At least this tree will keep its leaves all winter long.
Autumnal maple leaves.
On this visit I was quite keen to get some photos of the mushroom population. There weren’t so many of a big enough size to stand out as I strolled along, but if I just stopped for a moment to study the mulch that surrounds the base of every tree, there were far more mushrooms to be seen than most people would have realised. Perhaps these are waxcaps of some sort?
The distinctive spiny cupules of sweet chestnut. Apparently the nuts can’t attain their full size in the British climate, so the roasting chestnuts that appear in the shops for winter are imported from the continent. I had a bag of roast chestnuts at Edinburgh’s European Christmas Market last week – they were enormous and very tasty!
I’m fairly sure this is a hare’s foot inkcap (Coprinus lagopus). This mushroom is quite interesting; according to Wikipedia, “As the mushroom matures, the shape of the cap becomes more conical or convex, and finally flattens out, with edges curved upward. The veil is initially whitish, then turns to a silvery grey or grey-brown; it eventually splits up, becoming hairy (fibrillose). ... In maturity the gill edges dissolve (deliquesce) into a black liquid. These mushrooms are evanescent, lasting only last a few hours before death…”

Sometime last week I saw a conifer with these big solid looking cones. I was intrigued and plucked one off the tree. Fairly light but rock hard with a nice scent.
But what kind of tree has these weird cones? The Atlas cedar (Cedrus atlantica) [aka (Cedrus libani var. atlantica)]!
It is a native of the Atlas Mountains in Algeria and Morocco and is apparently one of the most planted decorative conifers in Britain. Which makes it all the more surprising that I've never noticed one before.
