Its a tangled time of boulders and creepers,pools of doubt a nd mossy melancholy. Will I get past this test?
Priory Walk / Drayton Gardens The pillar box is around 100 years old (Edward VII 1901 - 1910) the age of the tree is anybody's guess. It was clearly a poor piece of planning to plant them so close together but does make them both more interesting now.
Taken today in the morning in Botanic Garden,Bucharest-Romania...
a few things are left from the summer and autumn to shoot...:) but still have ideas...
au ramas putine lucruri de la vara si toamna de fotografiat dar inca mai avem idei...;)
This one has a perfect histogram ;)
A lot of pollarding going on.
As much as I dislike plane trees in Sydney, I'm willing to give them another chance over here, knowing that they're somewhat more native.
Platanus × acerifolia / London Plane Tree
The London plane tree is a very well known, common street tree, particularly in London, where it was massively planted in the 19th century, possibly because it appears to thrive in urban conditions and is resistant to pollution, and heavy pruning.
It has long been considered to be a hybrid between the American sycamore and the oriental plane first recorded in 1663. It's recognisable for its attractive, mottled patchwork, flaking bark and large palmate leaves. The fruit is produced in spring and hangs in burr-like clusters. They persist well into the winter and the following year, and look particularly interesting when the tree has lost its leaves, and the branches have a clear blue winter sky above.

Platanus × acerifolia / London Plane Tree
Platanus × acerifolia, Platanus × hispanica, or hybrid plane, is a tree in the genus Platanus. It is often known by the synonym London plane,[2] or London planetree. It is usually thought to be a hybrid of Platanus orientalis (oriental plane) and Platanus occidentalis (American sycamore). Some authorities think that it may be a cultivar of P. orientalis.[citation needed]
Description
The London plane is a large deciduous tree growing 20–30 m (65–100 ft), exceptionally over 40 m (130 ft) tall, with a trunk up to 3 m (10 ft) or more in circumference. The bark is usually pale grey-green, smooth and exfoliating, or buff-brown and not exfoliating. The leaves are thick and stiff-textured, broad, palmately lobed, superficially maple-like, the leaf blade 10–20 cm (4–8 in) long and 12–25 cm (5–10 in) broad, with a petiole 3–10 cm (1–4 in) long. The young leaves in spring are coated with minute, fine, stiff hairs at first, but these wear off and by late summer the leaves are hairless or nearly so. The flowers are borne in one to three (most often two) dense spherical inflorescences on a pendulous stem, with male and female flowers on separate stems. The fruit matures in about 6 months, to 2–3 centimetres (0.8–1.2 in) diameter, and comprises a dense spherical cluster of achenes with numerous stiff hairs which aid wind dispersal; the cluster breaks up slowly over the winter to release the numerous 2–3 mm (0.08–0.12 in) seeds. The London Plane is one of the most efficient trees in removing small particulate pollutants in urban areas.[3]
It shares many visual similarities with Platanus occidentalis (American sycamore), from which it is derived; however, the two species are relatively easy to distinguish, considering the London plane is almost exclusively planted in urban habitats, while P. occidentalis is most commonly found growing in lowlands and alluvial soils along streams.[4]
Origin
The species was formed by hybridization in the 17th century after P. orientalis and P. occidentalis had been planted in proximity to one another. It is often said that the hybridization took place in Spain, but it could also have happened in Vauxhall Gardens in London where John Tradescant the Younger discovered the tree in the mid-17th century.[5][6] The leaf and flower characteristics are intermediate between the two parent species, the leaf being more deeply lobed than P. occidentalis but less so than P. orientalis, and the seed balls typically two per stem (one in P. occidentalis, 3–6 in P. orientalis). The hybrid is fertile, and seedlings are occasionally found near mature trees.
Controlled reciprocal pollinations between P. occidentalis and P. orientalis resulted in good yields of germinable seed and true hybrid seedlings. Crosses of both species, as females, with P. racemosa and P. wrightii produced extremely low yields of germinable seed, but true hybrids were obtained from all interspecific combinations. Apomixis (asexual reproduction from non-fertilized seeds) appeared common in P. orientalis.[7]
In 1968 and 1970, Frank S. Santamour Jr. recreated the P. orientalis by P. occidentalis cross using a P. orientalis of Turkish origin with American sycamores (P. occidentalis). The offspring were evaluated following several years of exposure to anthracnose infection. Two selections, 'Columbia' and 'Liberty', were released in August, 1984.[7][8]
Taxonomy
Platanus × acerifolia was first formally described in the botanical literature by the Scottish botanist William Aiton in his 1789 work Hortus Kewensis as a variety of P. orientalis.[9] Aiton described this variety with a two-word Latin diagnosis, "foliis transversis", and called it the Spanish plane tree.[10] In 1805, Carl Ludwig Willdenow chose to elevate Aiton's variety to species rank, publishing the new species P. acerifolia in the fourth edition of Species Plantarum.[11][12] The species name was then modified to include the multiplication symbol to indicate its suspected hybrid parentage. The other name commonly used for this taxon, Platanus × hispanica auct. non Mill. ex Münchh., is a nomen dubium based on an uncertain description.[13][14]
Cultivation
The London plane is one of 50 Great British Trees that the Tree Council selected in 2002 in honour of Queen Elizabeth II's Golden Jubilee.[15] The list specifically mentions Britain's first London plane being in the city of Ely, Cambridgeshire.
The London plane is very tolerant of atmospheric pollution and root compaction, and for this reason it is a popular urban roadside tree. It was planted extensively in Victorian times to weather the pollution of London. It is now extensively cultivated in most temperate latitudes as an ornamental and parkland tree, and is a commonly planted tree in cities throughout the temperate regions of the world, in London and many other cities.[5] It has a greater degree of winter cold tolerance than P. orientalis, and is less susceptible to anthracnose disease than P. occidentalis. Under the synonym Platanus × hispanica, the tree has gained the Royal Horticultural Society of Great Britain's Award of Garden Merit.[16][17]
The tree is fairly wind-resistant. However, it has a number of problems in urban use, most notably the short, stiff hairs shed by the young leaves and the dispersing seeds; these are an irritant if breathed in, and can exacerbate breathing difficulties for people with asthma. The large leaves can create a disposal problem in cities, as they are tough and sometimes can take more than one year to break down if they remain whole.
London planes are often pruned by a technique called pollarding. A pollarded tree has a drastically different appearance than an unpruned tree, being much shorter with stunted, club-like branches. Although pollarding requires frequent maintenance (the trees must usually be repruned every year), it creates a distinctive shape that is often sought after in plazas, main streets, and other urban areas.
I love the contrast here between the incredible sun scorching the rocks with a white searing heat and the cool dark shadows that are now my companion to soothe me as I clamber onto the plateaux.

The Diarizos Valley lies west to south west of the Troodos mountain range and takes its name from the river Diarizos which runs through it. This valley has a wide variety of fauna and flora, with a number of protected species.
The bridge of Tzelefos is a medieval Venetian bridge located in the mountains of Paphos at the borders of Phini, Agios Nicolaos and Pera Vasa close to the Arminou Dam. This one-arch stone bridge has 10.70 m span and 10.7 m width
The Troodos National Forest Park covers an area of 9,147 hectares around Mount Olympus. It is an area of great natural beauty, suitable for activities such as hiking, biking and camping .
Cyprus has the warmest climate and warmest winters in the Mediterranean part of the European Union.
16 (17?) Feb 2002, from my journal: " In our hotel--it's just fine, the trip was good on the train, we both got to take short naps. Just back from a walk around the neighborhood, including a head-on view of the Staatsoper, and then dinner at "Bistro", in which R caught his menu on fire, from the candle on the table. The only casualty (other than the menu) a few ashes on R's trousers."
Caledonia waterfalls, is one of the highest water falls in Cyprus. It is located on Platres village in Troodos and the water fells from a height of 12 meters. It can be reached via a walking path.
Caledonia waterfall is surrounded by forest in a very beautiful area with breathtaking views. The trail is 3km long and can last up to 2 hours. It can also be divided into two parts, the first one which is the higher one that leads to the waterfalls and the second one which leads from the waterfall to Platres.
