Gather Your Rosebuds

This quest rewards a Basket of Draconic Flowers, which, upon use, contains 1 of each of the 5 flowers you gathered for the quest. Each one has a name that corresponds with one of the 5 dragonflights. They are white items, which implies they are used for something, but I can't find any use for them and they cannot be vendored. I hesitate to delete them until I know if they have a use. If they have no use, I cannot even figure out the purpose of this quest other than just for flavor. Thoughts?

Edit: Turns out they unlabeled consumables that give your character a glow. Right-click to use. If you don't care about that, you can safely delete them.

The quest name is a reference to the most famous poem by the celebrated English poet Robert Herrick (1591-1674), entitled "To the Virgins, to Make Much of Time."

Gather ye rosebuds while ye may,
Old Time is still a-flying;
And this same flower that smiles today
Tomorrow will be dying.

The glorious lamp of heaven, the sun,
The higher he's a-getting,
The sooner will his race be run,
And nearer he's to setting.

That age is best which is the first,
When youth and blood are warmer;
But being spent, the worse, and worst
Times still succeed the former.

Then be not coy, but use your time,
And while ye may, go marry;
For having lost but once your prime,
You may forever tarry.

Turns out they're consumables that give a lil visual effect on your character for 5 minutes! Doubt you'll need to keep them at all so use them or delete them :p
