5 gem (1x3-6*) - 3*

20 gem (11x3-6*) - 4 3*, 6 4*, 1 5* (Heart Vine new)

30 gem (5x4-6*) - 4 4*, 1 5* (Coral Flower new)

50 gem (6x5-6*) - 5 5* (Anthurium/xmas Iberis/Nandina new, Sarcandra/Heart vine dupes), 1 6* (Bush Clover new)

100 gem (6x5-6*) - 3 5* (Texas Bluebell/Candlebark/bride Ardisia new), 3 6* (miko Lycoris/Aizoon Stonecrop/Saffron new)

All in all, 4 new 6*s and 8 new 5*s from 205 flower gems. Rolling 4 6*s is well below the global expected average, but eh, my luck with pulls in this game tend towards the horrifically bad anyway. Getting just 1 or 2 would've been well within expectations :P

And I still have 355 gems left.
