The city council has recently made a big effort to get the alleged flower stalls on the Bloemenmarkt (flower market) to sell more flower and less made in Taiwan tourist tat. There has been some improvement.The best stalls for flowers are the two at either end. Beware of bargain bunches of tulips. They often wilt very quickly. My mother in law keeps them wrapped up and plunges them into cold water for a couple of hours. To stop them growing too long and spindly in the vase, she sticks a pin through the stalk just below the bloom.
