Required EXP for level 1 to 80:
5★ Flower Knight: 196200 (153000 with 9x100 year Manyus)
6★ Flower Knight: 204015 (160815 with 9x100 year Manyus)
So what you're saying is that if you feed the sapling too much, you're basically wasting resources, since she'll give more xp than you need. Makes sense.
