All the gardens and all the field have beautiful tulips blooming. They will be in bloom through the end of April. Beyond that will depend on the weather (wind, heat, rain, etc. all effect how long the gardens can leave the tulips before they are spent). The featured photo is of a RoozenGaarde field. Here are some pictures taken April 17-19 of the four gardens:
