Burgeoning Spiderwort

The Burgeoning Spiderwort is a plant in Pikmin 2 that produces the berries that are needed to make ultra-spicy spray and ultra-bitter spray. They are found only on land, and only in specific places. Sometimes Ravenous Whiskerpillars appear in the area of them, as well as some type of fungus (maybe) that shows up and covers the plants. This is destroyable with a large group of Pikmin.

Valley of Repose

There are none of them in the Valley of Repose due to the climate.

Awakening Wood

There are two near the landings site in Pikmin 1. In this area 2 Whiskerpillars appear. Both of these produce red berries. A mold may also appear here.

There is one near the area where the Iridescent Flint Beetle is, but takes 6 or more days to appear, it is also on a ledge, and only produces red berries.

There is finally a last one near the entrance to the Bulblax Kingdom, but may be a hassle to get to. It only produces purple berries.

Perplexing Pool

There are two near the where Gherkin Gate treasure's location is. They both produce purple berries, and molds and 3 Whiskerpillars appear here.

Beyond the entrance of the Citadel of Spiders, there is a plant steming from the water, so only Blue Pikmin can attack it. Only red berries are produced from it.

Wistful Wild

As you near the depluggable lake, or the electric gate, or better said, the path to the entrance of the Hole of Heroes, you will find a large field with 3 of the specified plant. All of them produce both kinds of berries. There are 3 Whiskerpillars here and a mold will cover each individual plant.
