Dahlias are native to Mexico and they played an important role in Aztec culture. Dahlias became increasingly popular throughout the world over the course of the 19th and 20th centuries. Dahlias are frequently used as a symbol of elegance and dignity. Dahlias are grown in the western part of Holland by professional bulb growers. There are also many dahlia societies in Holland with members who grow dahlias as a hobby. Dahlias are not just used in gardens anymore, but they are also popular as cut flowers. Because of the various shapes, colours and sizes, dahlias are a great addition to any flower bouquet.
