Around the 60s the flower pattern was extremely populair and it will always be! Of course it's the most perfect match for a tropical environment.
Did you know that, back in the days, surfing was discovered in Polynesia and brought to Hawaii a little later. For the people of Tahiti it wasn't just only a sport, but it also had a religious function. Boards could only be used by the head of a tribe and later also by the royals. They always decorated everything with flowers and wore traditional 'Lei's', the typical flowerchain.
So that's where the whole hype started off. Every brand was using the hibiscus, ivy, Lehua, mokihana, kukui and Kuana'oa flower. Other populair ones were: pineapple and herringbone prints. If you look at the very first prints, you see that flowerprints were the hottest. And they still are!
