Can you buy flowers and if so how?

Flowers are purchased by buying decoration with coins or diamonds in the decoration shop (cash register icon). The flower value for each decoration is denoted in red next to the flower symbol. The flower count will be added to your game after construction is complete and the red ribbon is removed from it. Buying too many low-flower decoration will cause you to run out of island space. High-flower decoration will advance your game further. Flowers can also be obtained from renovating landmarks and upgrading buildings and getting deliveries from Jack's plane.
