Answer: Many types of trees and shrubs can be started from cuttings and yes, there are various special requirements (including time of year collected) depending on what you are trying to propagate this way. I think the best way to explore all the possibilities would be to look at a good reference book. One of the best is Michael A. Dirr's "Manual of Woody Landscape Plants: Their Identification, Ornamental Characteristics, Culture, Propagation and Uses" (ISBN 0875637957). This was newly revised in 1998 but any edition would be a good start. I hope you have lots of room to plant all these new "woodies"!
