Yangjae Flower Market in Seoul is one of the largest in Korea. It is divided into several different zones, from whole sale to retail, it also has auction house and a whole floor of silk flowers, ribbons and other flower arranging items. The whole sale section of the market is open from 1am and closes at 1pm while the rest of the green houses and artificial sections are open until about 3pm. I headed there with a friend a few weeks ago, and even though I did't think I was mad about flowers, we spent a good number of hours wondering around, purchasing greenery and snapping photographs. It is well worth the trip, and I'm sure you won't leave empty handed. And succulents like these ones (click here) were only W1000 a pop...win!
