Florian's photos: Dahlia season
Fall is not only the season of spectacular fall colors, but also the blooming season of Dahlias. The wild form of Dahlias is a native to Central America, Colombia and Mexico, but these plants are most famous for the thousands of cultivars that have been bread since 1813. For the scientifically inclined among you, I may mention that Dahlias have eight sets of chromosomes (they are so called "octoploid", humans for example have only two sets of chromosomes and are therefore diploid), which is the main reason for their enormous variability. At this time of the year, over 270 varieties of Dahlias can be admired blooming on the island Mainau, in the Lake of Constance. If you are in that region in the next couple of weeks, I highly recommend a visit!
