I recently went to the Party Rental Ltd. Fall Open House (see more on the new items available later). They had the best fall arrangements there - and I'm not sure who the florist is - arrangements that you really just want to take a bite out of.
The arrangement featured above featured burgundy and wine red dahlias in a rustic pot. I love dahlias, though they can be hard to work with since they aren't always consistent looking.
This is a close up of baby watermelons that the florist wrapped, still on the vine, around the rustic container. I LOVE this - probably one of my favorite floral finds so far this season.
The second fall arrangement incorporates a variety of seed pods. This has a more elegant weed feel, but would mesh very well with a rustic farm, barn or ranch wedding. The different color berries add some fall colors. You can easily incorporate a few seed pods into your arrangements or bouquets from any season - they really lend something different and interesting to your florals.
