Everytime I've come here everyone has been so nice! I get shy easily but it's so easy to feel welcomed here. They have a wonderful selection of flowers, vases, decorative items... and great prices too. This place has been my one and only place I arrange my bouquets at ever since I came to STL. This is one of my happy places 🩵

I ordered the Elegant White Modern Traditional Fan Display Saturday evening for my friend's funeral service on the following Monday. Not sure whether the flowers would be delivered on time for the service, since the WKF was closed on Sunday. Monday 8:15am, I was pleasantly surprised when receiving a confirmation email of the delivery. The flower display looked PERFECT, just as shown in the online picture. I'm glad that I chose WKF. They have quite a lot of options for various occasions, all reasonably priced. Definitely would recommend WKF for local services in St. Louis.

I had a beautiful experience during my visit on 11/15/23!! I walked into the place and I was instantly in the center of a ROSE 🌹!!! From the smell of fresh flowers 💐 to the visual of beautiful boutiques & vases, to the friendly people inside!! Oh, they hv gorgeous trees, I was wanting fresh beautiful flowers and didn't want to go to grocery store; & I wanted variety!! Never been here b4 on Lasalle, flower district & was in awe (I love all things nature/natural) I was in heaven, I was able to create my own boutique, wasn't being rudhed and I didn't know where to start; simply bcuz I thgt they were putting it 2gather!! Nope, I did and it made my gift even more special!! Thanks to (Karen, Andrew) & the production staff involved who gave me a crash course in flowers, vases, how to spread etc...
