Yes absolutely not the cut flowers for ten$ the plants themselves were going for ten dollars. Large plants with flowers and buds. The lotus are huge I could hardly get one into the back of my 4x4, even though pot size is always nice and little because they use clay soil. These are cheap cut flowers because they are local, there are many more expensive flowers like protea and heliconias and peonies etc, those can go for at least ten dollars or more US per bloom.
Besides, Hong Kong has the one of the highest number of dollar millionaires per % of the population in the world, so all in all extremely cheap for all concerned. Mainland China too has an enormous market of extreme wealthy people, they buy many apartments here, five million US and up for a decent apartment (nothing extraordinary) here is almost the norm, for that you wont even get more than three bedrooms, sometimes not even a balcony.
Mainland China also has many more poor people, and local plants and flowers are much cheaper there, import ones very expensive.
Water lilies and lotus do well as a cut flower, just depends on the variety and freshness, same as in the pond. Mostly bought just for the rich perfume. With those big top heavy "football" size doubles (million petals as they are called) lotus they also fold back each petal into an interesting shape like a large rose, cut of the stem and float it in a bowl, they can last like that for up to a month. Very popular in hotels for table decoration etc.
