In the old parchments of the bulb industry is written that this Tulip was already in production in 1933. It was the grower Mr Bakker from Enkhizen who found this Tulip as a colour mutant in his stock of Peach Blossom. He fancied the Tulip so much that he named her after the father of motherland; William of Orange. At that time this Tulip already was an all-round Tulip, suitable for growing indoors on pots as decorative houseplant, suitable for growing as cut flower during the winter and she proved to be a great Tulip for the garden. Her grandiose, profuse orange colour made her a true eye-catcher in the garden. This Tulip was able to bear his great name with verve and she was halfway the last century one of the most numerous Tulips grown in Holland. I’m almost certain that this Tulip also ended up in many empty stomachs during the hunger winter of 1945 because she was grown in large acreages north of Amsterdam by the West Frisian growers during that time. But nowadays this Tulip is hardly grown anymore. For a modern Tulip grower her increase rate is not fast enough and there are present-day Tulips that perform better. But none of the newcomers has that nice libertine, fluttering flowers that Willem van Oranje shows us. I love her, so I keep on growing my little stock of Willem van Oranje for the real Tulip enthusiasts. When the flower just opens she sometimes shows some yellow, but when she develops and matures Willem van Oranje shows us what a real nice orange Tulip is supposed to look like.
