The theme of this year’s show was ‘bonsai forests’ and the subtheme will be kusamono. Bonsai, a horticulture art form developed in Japan, is now practiced world-wide. Iowa bonsai enthusiasts are active in multiple styles of bonsai including not only the stereotypical leaning pine tree but also temperate deciduous trees, group plantings (forests), tropical material, and trees growing on and in rocks instead of in pots.
