Keukenhof 75 project leader Annemarie Gerards told Anadolu that the gardeners plant 7 million tulip bulbs by hand, from the first week of October till mid-December.
"We have roundabout 600, maybe 800 tulip varieties," she said, adding that 80% of the visitors are foreigners.
Russian visitor Yulia Mikhaylova told Anadolu that she came to see Keukenhof during her trip to the Netherlands.
Charles Dudley, who came from London, said the vibrant colors of tulips feel like they have been "painted."
The garden of 32 hectares hosts 40 gardeners, and visitors can also enjoy a walking path of 15 kilometers (9 miles).
