Horsetail

The Horsetail is a plant that is brownish and stiffly sticks out of the ground like a post. This hardy plant can survive in soil conditions with few nutrients. Horsetails, unlike most plants, have retained the primitive method of reproducing via spores.

Olimar's notes

 * "This variety of horsetail is prevalent in regions with low nutrient content in the soil. Unlike most other plants, this particular species propagates itself through the release of spores."

Louie's notes

 * "Remove and discard the primitive, scaly leaves, then blanch the tender stock in a buttery broth."

In Pikmin: Redemption
In Pikmin: Redemption, Horsetails are almost completely wiped out of existence. The only living specimens are found in The Oasis.
