Nectar weed

Nectar weed resembles a patch of long grass. Its purpose for Pikmin is as a source of nectar: they can extract pools of nectar from it seemingly by plucking out single blades of grass, though it is possible for a patch of nectar weed to yield no nectar at all.

In Pikmin: Attack of the Breadbugs
Nectar weed appears in Pikmin: Attack of the Breadbugs. It can be found in the Beginner Territory, Marsh Territory, Loaf Territory, and Hidden Territory of the Land of Wonders. Up to ten Pikmin can pluck patches of nectar weed at once, and Captain Olimar can assist Pikmin in plucking the blades, even if ten Pikmin are already working on it.

In Pikmin: Wide World
Nectar Grass is an invaluable source of nectar in Pikmin: Wide World. Pikmin will pluck blades of Nectar Grass until the entire patch is gone, and every blade plucked has a chance to produce nectar. An unlimited amount of Pikmin may work on plucking blades at a time. Pikmin are not distracted by Nectar Grass and must be directed to work on removing a patch of it. Idle Pikmin, however, will automatically begin working on it. Leaders can also pluck blades of Nectar Grass.
