My understanding is that the Dutch find displays of nationalism suspicious. This is quite understandable when one considers a very patriotic neighbor once promised on one day that they would leave The Netherlands alone based on their previous neutrality, and then same country invaded them the next day. So although Holland is well known for flowers, I doubt one would find an entire field carefully planted to represent their nation’s flag, especially considering that the Dutch flag is only allowed to be displayed on certain days and at well defined times.
The U.S. has a different take.
Floral Flag is 740 feet long and 390 feet wide and maintains the proper Flag dimensions as described in Executive Order #10834. This Flag is 6.65 acres and is the first Floral Flag to be planted with 5 pointed Stars comprised of White Larkspur. Each Star is 24 feet in diameter. Each Stripe is 30 feet wide. This Flag is estimated to contain more than 400,000 Larkspur plants with 4-5 flower stems each for a total of more than 2 million flowers. (Link)
Thus, to honor the 240th Flag Day of my home country, I present you with the image of the US flag, this over the top display–and I hope my tolerant Dutch friends will understand.
