How can I find out how many flowers I have on my island?

There is nowhere in the game that shows the cumulative flowers. However, I have a running list that shows how many flowers you must have on your island(s) to open a level.

To reach level 500 (=chapter 100 = end of volume 1), you must have 142,010 flowers.

To reach level 750 (=end of volume 2), you must have 225,310 flowers

To reach level 875 (=end of volume 3), you must have 266,820 flowers

To reach level 1050 (=end of volume 4), you must have 323,630 flowers

To reach level 1225 (=end of volume 5 and max level at this time), you must have 387,101 flowers.

Of course, this does not include any flowers of decoration you may have in your storage ship.
