Mosaiculture

Posted on Tuesday, 30 September, 2014Sunday, 20 August, 2017 by Zheluo Cai

Mosaiculture should be distinguished from topiary, which features mostly shrubs pruned to create different shapes. Mosaiculture is a horticultural art that involves creating and mounting colourful two- and three-dimensional designs, sculptures and reliefs made primarily from plants with colourful foliage that consists generally of annuals, and occasionally perennials.

Mosaïcultures Internationales, a triennial competition, is an exhibition of horticultural art and a chance for the representatives from parks, gardens and green spaces around the world to exchange ideas. All works presented must represent something of the participant’s culture while responding to a predefined theme and complying with the principles of sustainable development. A few of the exhibits from the 2013 competition at the Montreal Botanical Garden are shown here.

Arp 188 and the Tadpole's Tail.
Image Credit: Hubble Legacy Archive, ESA, NASA; Processing: Faus Márquez (AAE). Distant galaxies form a dramatic backdrop for this disrupted spiral galaxy Arp 188, the Tadpole Galaxy. It is 420 million light-years distant toward the northern constellation of the Dragon (Draco), with its eye-catching tail of about 280 thousand light-years long, featuring massive, bright blue star clusters. It is theorised that a more compact intruder galaxy crossed in front of Arp 188 - from right to left in this view - and was slung around behind the Tadpole by their gravitational attraction, with tidal forces drawing out the spiral galaxy's stars, gas, and dust forming the spectacular tail. The intruder galaxy, 300,000 light-years behind the Tadpole, is seen through foreground spiral arms at the upper right.

Sunflowers (Tournesols) is the name of two series of still life paintings by the Dutch painter Vincent van Gogh. The first series, executed in Paris in 1887, depicts the flowers lying on the ground, while the second set, executed a year later in Arles, shows a bouquet of sunflowers in a vase. In the artist's mind, both sets were linked by the name of his friend Paul Gauguin, who acquired two of the Paris versions. On March 30, 1987, Japanese insurance magnate, Yasuo Goto, paid the equivalent of US $39,921,750 for van Gogh's Still Life: Vase with Fifteen Sunflowers at auction at Christie's London. The painting currently resides at Seiji Togo Yasuda Memorial Museum of Modern Art in Tokyo.
