This is a feature street market in Mongkok located just north of Prince Edward West Road, around a 5 minute walk from both Prince Edward and the Mongkok East MTR Stations. The Mongkok Flower Market has dozens of shops and is worth seeing anytime of of the year. However, it is particularly interesting now during the Chinese New Year season.
At this time of year, the flower market is thriving with shops and added stalls filled with seasonal flowers, plants and decorations. You'll be able to see daffodils, orchids, chrysanthemums and holiday specials including Narcissus, peonies, kumquat (mandarin orange) plants, bamboo shoots, colourful willow stems and cherry blossom stems amongst others.
Do expect crowds when you plan to visit the Flower Market but especially during the Chinese New Year - to a point of being uncomfortable in the evenings and weekends. As such, consider midday weekday visits during CNY when things are more manageable and its easier to take pictures.
