Upon talking to a merchant that has this quest, you'll have the option Valtuila Lilly. He will tell you the following:
I'm sorry I'm not in the greatest of moods. You see, every year I go to visit my mother's grave, rest her soul. And when I do, I bring her her favorite flower and place it at her tombstone. The problem is that over time these flowers have grown more and more scarce. I dare say you are lucky to even hear about one anymore!
The flower is called a Valtuila Lilly. They used to grow everywhere but for some unknown reason they've been fading out of existence. I did spot one recently however.
A pirate came by here to buy some goods and I noticed he carried one with him. He referred to himself as some kind of herbalist. I tried to barter with him and get him to sell me the flower but he refused. I must have irritated him because he ended beat attacking me, stealing half my things, and leaving me for dead.
If you come across any of these 'herbalists', perhaps you'd be willing to obtain a Valtuila Lilly for me? I've got a fairly valuable ring that I would be willing to part with if you do.
