I glitched on this quest...

I did it in its entirety as far as I can tell and it won't complete. After I traded them already Luquelot(sp?) keeps asking me for them. What may be the problem is when the greens popped in the garden nearby I picked up 1 out of 3 and the others disappeared. I got the big message that companions are unlocked but I can't summon my chocobo. I even bought more greens at the nearby npc and it didn't help. Also, I hotbarred the summon icon and I got a message that said "action not learned yet." Can anyone relate?
