Depending on the season, the flowers you can find from any of the several merchants here will be either fresh or dried. Either way, they'll be relatively cheap (think $15 for a gargantuan bouquet), and while some vendors have better arrangements than others, all will be at least have decent.
It may be tempting to get the flowers immediately on the corner of 1st and Pike, but those cost about 4x what you'll pay if you wander deeper into the Market.
