Where do the dahlias come from and what are their typical characteristics?
Dahlias originally come from Central America, more precisely the high plateaus of Mexico and Guatemala were formerly their natural distribution area. There they were used as useful plants because their starchy tubers can be prepared just like potatoes.
It was only after Christopher Columbus discovered America that these garden plants came to Europe around the 18th century. The beautiful flowering plant was named after the Swedish botanist Andreas Dahl. Today the colorful dahlias can be seen on many balconies and in almost every garden.
