Dahlia's come in many shapes, sizes, and colors. They are a versatile flower and one of my personal favorites for this reason. I currently preparing for an October wedding and one thing that I do is see where I can source the best blooms. One source is Aztec Dahlia's in Petaluma. They have cut flowers you can buy or you can by the tuber and grow your own. Here is one of the varieties that I will be using, Boogie Nights.
Another place to go see these flowers is at the Dahlia Dell in Golden Gate Park which is also proof that you can grow these flowers that are native to Central and South America even in our foggy climate.
