These images are all from Jesperhus, a park in Denmark that includes a Hans Christian Andersen fairy tale flower garden!
According to Wikipedia, 6 of Andersen's tales are recreated with flowers. I can't find a list of the six tales, only images for these four:
Ugly Duckling (I assume)
Princess and the Pea
The Tinder Box
UPDATE: Reader Rossichka shared in the comments that this statue of Little Mermaid and one of Thumbelina is also at the park. This one has gotta be Steadfast Tin Soldier. But not being made of flowers, I wonder they count? This would make seven total.
