Laib is most well known for his use of large quantities of intense, yellow pollen. A slow and deliberate process, the artist collects the pollen from around his home in southern Germany during the spring and summer months. Working with the natural sequence of the seasons, he harvests the pollen on each tree or flower when it is in bloom, beginning with hazelnut, moving on to dandelion and other flowers, and finally ending with pine. Each type of pollen is unique in color and size. Laib exhibits the pollen in a variety of ways, most famously sifted on a stone or concrete floor, creating a field of brilliantly hued pollen. Final sizes are determined by the abundance of the pollen itself; with pine being more plentiful, therefore creating larger sifted areas. The pollen is also exhibited in glass jars or small piles. In addition, the pollen is sold to collectors and institutions in glass jars, without any stipulations as to how it should be exhibited. For Laib, the pollen is the artwork, not the process of collecting it or presenting it sifted on the floor or in jars.
