why do some florists charge so much for roses?

simple, because they can...Roses have a very high markup, so most florists charge what people are willing to spend on them. There are certain times of the year where the wholesale price of roses go through the roof. The rest of the year, roses are relatively inexpensive. Florists can choose to charge a lower price, but most of them do not. Luckily we are different and want our customers to get value for their money
