If you you succeed the quest then you must go to the left of Gemino's tree, and enter a cave on the left side of the screen with a hidden wall, breaking that wall will reveal a tomb, if you didn't fail the quest gemino will be there holding the tomb open and you can jump inside and give the dried flowers to Engracia to get your reward.

If you killed too many bosses before giving Gemino the thimble filled with oil you will have failed the quest, and to get the reward you have to drop down in the abyss using Linen of Golden Thread to not die, then walk to the left of the screen and give Engracia the flowers.
