The Art of Bonsai, Scott Elser

The art of bonsai is in training the trees in containers to represent ancient trees found in nature. Bonsai trees can live to be hundreds of years old. Scott will talk about bonsai and the breadth of styles, sizes and species that it encompasses with live examples. He will also show us how to make and maintain bonsai specimens.

Scott is a national award winning bonsai enthusiast whose broad collection of trees includes native, conifer, deciduous, fruiting, and flowering bonsai that he shares regularly at local and national shows.
