  • Seriously, if you don’t use her you’re missing out

    I can’t speak highly enough of Colleen and her crew and what she was able to transform my wedding into. We were across the country so we had to meet only virtually with her and sent some Pinterest inspiration along with the colors of our bridesmaids dresses. She was honest, understanding, and quick to respond to any changes or questions. She was extremely knowledgeable about local plants and what would work with our wedding theme. When we finally got to meet her and see our outdoor rented wedding set up it was beyond what we could have even imagine. She included everything we wanted and then some. It was perfect and she came early the next day to take everything down. I honestly couldn’t recommend anyone any more highly.

  • Perfect wedding flowers!

    Colleen and her team took my vision and crafted the most gorgeous bouquets, centerpieces, and flower crowns for our wedding in September 2021. You absolutely cannot go wrong in working with Colleen. Her artistic skill will bring your event to life!

    Colleen is an incredible person to work with. I have sold her flowers from my farm and done freelance floral design work with her. Her business is a model for sustainability practices in the floral industry. Colleen knows her stuff and I am consistently impressed by her breadth of knowledge. She is a great communicator, and amazing at turning a couple’s floral vision into reality. She is extremely professional and a perfect mix of creative and technical when it comes to designing with flowers and building installations. I’d want her working on my wedding!

    Colleen is, without a doubt, the best vendor I worked with for my wedding. She is easy to work with, very generous with her time and emotional intelligence/energy, and creates beautiful designs. I believe every single guest at our wedding complimented the flowers - no exaggeration. We kept things “pretty simple” with florals, but that is the very last word I would use to describe what Colleen designed for us. Because of the late frost in Maine this year, we were lucky to get flowers entirely from Colleen’s farm, which was super special. Another reason I loved working with Colleen, is that she is very eco-focused - something important to us. She works tirelessly to promote sustainable floral design and farming practices, and the results are incredible. I still think about my wedding florals daily, and you will too if you work with Colleen!
