Joyce Florist is the place I go to most often if I need flowers in the Tenafly area.
The store is small, but the selection is definitely adequate. The owner is extremely nice and is always willing to help out. I once was away and wanted to send flowers to my father as a congratulations. The owner was more than willing to take the order by phone and deliver it personally.
I have always found very nice arrangements at Joyce Florist. The flowers are always fresh and the prices are extremely fair.
I would definitely recommend this florist if you are in need of one in the Tenafly area.
