Female metro passengers hold flowers presented to them by metro workers, prior to International Women's Day in Kiev, Ukraine, 02 March 2016. The hustle and bustle of the morning commute is broken up by an unexpected surprise. The first passengers to step on the train receive – a warm welcome and a pot of flowers. One woman says, “It's very nice. All the running around and then you're given a flower, it's not often. It's very nice. I'm going to take care of this flower”. International Women's Day first emerged from the activities of labour movements at the turn of the twentieth century, in North America and across Europe, it is celebrated on March 08 in many countries around the world.

“The titan arum or Amorphophallus titanum (from Ancient Greek amorphos, “without form, misshapen” + phallos, “phallus”, and titan, “giant”) is a flowering plant with the largest unbranched inflorescence in the world. The titan arum's inflorescence is not as large as that of the Talipot palm, Corypha umbraculifera, but the inflorescence of the Talipot palm is branched rather than unbranched”. – Wikipedia

These images have been created using a colour scanning electron microscope (SEM) by the award-winning Eye of Science, comprised of snapper Oliver Meckes and biologist Nicole Ottawa. For a decade the pair, based in Reutlingen in the south of Germany, worked with an old SEM they saved from the scrapheap, but for the last five years they have used a £250,000 FEI Quanta Series Field Emission SEM. Oliver said: “Flowers are beautiful in 'normal' view, but when you look closer, some parts get very bizarre and unexpected structures appear – flowers within flowers, worlds within worlds”.

German photographer Martin Klimas, who you may remember from his exploding porcelain figure series, creates breathtaking photos of flowers exploding into a million beautiful pieces. To achieve this effect, he soaks the petals in liquid nitrogen to make them brittle and hits the flower with an air gun.
