Being a florist in Sonoma County, I have access to some incredible flower farms. Last weekend, I did an event at Gloria Fererr Winery. If you have never been to Gloria Ferrer for bubbles, you must go! Beautiful views over looking the vineyards and some great Champagne.
So, for the arrangements, I needed some deep red and white Dahlias. I headed over to Petaluma to the Aztec Dahlia farm. This place is beautiful and open to the public. I met with the grower there and she let me hand pick the Dahlias I wanted. It doesn't get much fresher than that! For fall arrangements, (although, it doesn't feel like fall out here in CA) consider mixing soft textures like Dahlias, with more rustic textured flowers like these purple sea hollies.
