After healing the plant, right click on it to receive a rather nice buff... Song of Starflower +70 Crit and +10 to all resistances for 1 hour.

After cleansing, the flower gears up. Picked it for "Songflower serenade" = Increases critical strike rating and spell critical strike rating by 70 and all attributes by 15. Duration 60 minutes.

One strange warning. If you have full bags, and you want do the plant quest, you got strange error that you need some room in the bags, when you loot the cleansed plant.

It happens me with full bags. It goes normally for a buff, but because the looting, it use for short time one bag room and then immediately it buffs you.

With full bags, you lose the loot, and you cannot loot plant again. The loot indicator is gone.
But the plant is not gone! It's still there.
I think it's a bug, because you can loot always again even with full bags. Only here with plants it goes really wrong.

Why it use one bag room, it's still unfair and unlogic. Because it gives always the buff.

Second warning: don't loot next plant if you have already same buff. Dismiss the buff first, so you can get a new one from the plant.
Because you cannot loot again (same problem with full bags) the plant.

If you have a choice of which flower to 'uncorrupt', choose this one.

It adds 15 to all of your stats for one hour.

True, with the others you get more items but, this lasts longer (vs taking one of the others) than the others' 10 minutes.

It helps you slice through the satyrs like buttah. :)

Did this today on my 67 paladin twice. Didn't get the buff either time. Possibly because it's a grey quest for me? can anyone confirm this?

That's all fantastic and luvverly, but where is it?

you havta do the cleansing felwood quest first...then you get to clean these plants

anyone have any locations for any of the corrupted plants or are they a random spawn?

This quest is broken for now. If you inhale the songflower you will not get the stat buff and the crit increase. You will get a message that "the songflower was resisted".
A GM told me that it is broken and they are looking into it. Hopefully next patch will fix that.

After the flower is cleansed you can click on it to get an hour buff called "Songflower Serenade" that increases the chance to crit by 5% and adds 15 to all stats.
