Origin: Jumbo tulips
The tulips sold by Jumbo are grown by growers like Antoon Volwaren in Roelofarendsveen in the province of South Holland. Beautiful tulips start off with a good tulip bulb. The bulb will start to sprout if it is kept in the rooting room at a temperature of 5 degrees. The bulbs are then planted in the greenhouse and given enough water. At a constant temperature of 16-18 degrees the bulbs will soon grow into sturdy tulips. After 25 days, the tulips are ready to be harvested and they are carefully picked by hand. After that you will find them at a Jumbo near you.
