💐 Saved My Wedding Day

"I come here all the time, they have a great variety and such knowledgeable staff, so I would always recommend checking them out. But specifically I wanted to highlight the fact that they saved my wedding day! 72 hours before my wedding I had a florist back out on our ceremony flowers. Marianne and the staff were happy to help and completely knocked it out of the park! She did up 7 gorgeous baskets just like the inspiration photos I had shared. They lasted for the reception portion of our wedding which took place 2 weeks later as well. Nothing but positive things to say!"
