The Bud Stop on Union Street in the Marina has the most beautiful flowers to offer, I'm convinced of it. Every time I go down Union, I make a point to always stop here even if I'm not purchasing a bouquet to take home for myself.
They always have such an interesting variety of colors, and often times they have flower species I have never even heard of. They're always friendly and willing to answer your questions, let you smell your favorite blooms, and provide knowledge about what flowers would look good together in a bouquet, in your price range and more.
What buds, right?
