Freshly Picked Flowers

Freshly Picked Flowers is a token gift item given out by Thunder Bluff non-guard NPCs during the Love is in the Air seasonal event. These are combined into packages which are in turn hierarchically combined with other pledge packages for buffs and rewards.

All of the Love is in the Air token gifts are non-functional as regards their name and picture. Freshly Picked Flowers is not a functional bouquet item.

Source
Freshly Picked Flowers is the one and only token gift items that can be found inside a Gift of Adoration: Thunder Bluff or a Gift of Friendship: Thunder Bluff, given by Thunder Bluff non-guards NPCs as part of the Love is in the Air event. (The Gift of Friendship contains only the token gift; the Gift of Adoration contains other functional gifts as well.)

You will need one free inventory slot or a current stack of less than 20 Freshly Picked Flowers in order to remove a Freshly Picked Flowers from its container. To remove the Freshly Picked Flowers from its container, right click the Gift of Adoration or Gift of Friendship to open it.

Ingredient
If you have five or more Freshly Picked Flowers in your inventory, right clicking on any of them will consume five and create a Basket of Flowers.

Inventory space
The Gift of Adoration: Thunder Bluff and Gift of Friendship: Thunder Bluff container items do not stack. Opening your Gifts of Friendship: Thunder Bluff should save inventory space, since the Freshly Picked Flowers token gifts stack 20 high. It is generally useful to NOT autoloot a Gift of Adoration container - the Love is in the Air event items quickly consume any available inventory space. If you have autoloot turned on, you can hold down the shift key while right clicking the Gift of Adoration to not autoloot it. You can then remove only the items that you need at the moment.

Be careful when combining these into packages, the Freshly Picked Flowers token gift item stacks 20 high, but the Basket of Flowers package item does not stack at all.

Thunder Bluff non-guard NPCs
For the Love is in the Air gift items given by non-guard NPCs, the race of the NPC, not the location, determines which city's gift item you get. Tauren NPCs give Thunder Bluff gifts regardless of which of the participating cities they are in. For example, in Orgrimmar gives the Thunder Bluff gifts.

The innkeepers, though they are non-guards and have hearts over their heads, do not give gifts.

Transferability
This is a conjured item. It cannot be sold at the Auction House, mailed nor put in a guild bank tab, but it can be given, sold, or traded with other player characters using the trade window. Unfortunately, that means you cannot pass these directly to an alt on the same account.

Duration
This item is primarily useful during Love is in the Air and the seven day duration of the item is longer than the event, so is not a handicap. It does prevent you from saving these for the following year.
